6. The ROM-DOS system can now be operated in MS-DOS/PC-DOS prompt mode. That is, you can input commands to operate the

ROM disk and access files on the ADAM-5510.

** Note:

The ADAM-5510’s operating system is ROM-DOS, an MS-DOS equivalent system. It allows users to run application programs written in assembly language as well as high level languages such as C++.

However, there are limitations when running application programs in the ADAM-5510. For example, the

ROM-DOS command set does not include commands that operate through the console to control the screen, e.g. “CLS” (clear screen), etc. In order to build successful applications, you should keep these limitations and concerns in mind. For more detailed information, please refer to Chapter 6.

Introduction

1.1 Standalone Data Acquisition and Control System

The task of monitoring and controlling a process in a laboratory or an industry can be extremely complex. As the number of data collection points and process control actuators in the network increases, this task becomes more challenging. PC-based DA&C systems provide a high value alternative to older, more expensive technology in the control industry, but most systems require a desktop PC or equivalent at their core. Now Advantech's ADAM-5510 can operate a process control network independent of a desktop PC.

1.2 Features

1.2.1 Control flexibility with C programming

The ADAM-5510 is a compact PC in its own right and includes an

80188 CPU and a built-in ROM-DOS operating system. It can be used in a way similar to how one uses an x86 PC in the office. The

ADAM-5510 can be controlled by programs written in C language.

Given the prevalence of C language programming tools, this is a distinct advantage for many users and can result in a very short learning curve and very modest training expense requirements. See

Chapter 3 ADAM-5510 System for detailed technical specifications.

1-2

1.2.2 RS-232/485 communication ability

The ADAM-5510 has three serial communication ports, giving it excellent communication abilities. This facilitates its ability to control networked devices. Among its three ports, COM1 is a dedicated

RS-232 port and COM2 is a dedicated RS-485 port. These two ports allow the ADAM-5510 to satisfy diverse communication demands.

COM3 is a programming port for downloading or transferring executable programs from a host PC. It can also be used as an RS-232 communication port.

1.2.3 Complete set of I/O modules for total solutions

The ADAM-5510 uses a convenient backplane system common to the

ADAM-5000 series. Advantech's complete line of ADAM-5000 modules integrates with the ADAM-5510 to support your applications.

ADAM-5510

Chapter 1

A full range of digital modules support 10 to 30 V

I/O and relay outputs. A set of analog modules provide 16-bit resolution and programmable input and output (including bipolar) signal ranges. For details, refer to Chapter 4 I/O Modules.

A complete set of C language I/O subroutines are included in the

ADAM-5510's function library to reduce programming effort. Users can easily call these subroutines to execute the ADAM-5510’s I/O functions while programming in Borland C 3.0 languages. For a detailed description, refer to Chapter 6 Function Library.

1.2.4 Built-in real-time clock and watchdog timer

The microcontroller also includes a real-time clock and watchdog timer. The real-time clock records events while they occur. The watchdog timer is designed to automatically reset the microprocessor if the system fails. This feature greatly reduces the level of maintenance required and makes the ADAM-5510 ideal for use in applications which require a high level of system stability.

Installation Guidelines

2.2 Module Installation

When inserting modules into the system, align the PC board of the module with the grooves on the top and bottom of the system. Push the module straight into the system until it is firmly seated in the backplane connector. Once the module is inserted into the system, push in the retaining clips (located at the top and bottom of the module) to firmly secure the module to the system.

2-6

Figure 2-5: Module alignment and installation

ADAM-5510

Chapter 2

2.3 I/O Slots and I/O Channel Numbering

The ADAM-5510 system provides 4 slots for use with I/O modules.

The I/O slots are numbered 0 through 3, and the channel numbering of any I/O module in any slot starts from 0. For example, the

ADAM-5017 is an 8-channel analog input module. Its input channel numbering is 0 thru 7.

2.4 Mounting

The ADAM-5510 system can be installed on a panel or on a DIN rail.

Panel mounting

Mount the system on the panel horizontally to provide proper ventilation. You cannot mount the system vertically, upside down or on a flat horizontal surface. A standard #7 tating screw (4 mm diameter) should be used.

ADAM-5510

Figure 2-6: ADAM-5510 panel mounting screw placement

2-7

Installation Guidelines

DIN rail mounting

The system can also be secured to the cabinet by using mounting rails.

If you mount the system on a rail, you should also consider using end brackets at each end of the rail. The end brackets help keep the system from sliding horizontally along the rail. This minimizes the possibility of accidentally pulling the wiring loose. If you examine the bottom of the system, you will notice two small retaining clips. To secure the system to a DIN rail, place the system on to the rail and gently push up on the retaining clips. The clips lock the system on the rail. To remove the system, pull down on the retaining clips, lift up on the base slightly, and pull it away from the rail.

2.6 Wiring and Connections

This section provides basic information on wiring the power supply,

I/O units, communication port connection and programming port connection.

Power supply wiring

Although the ADAM-5510 systems are designed for a standard industrial unregulated 24 V

power supply, they accept any power unit that supplies within the range of +10 to +30 V

. The power supply ripple must be limited to 200 mV peak-to-peak, and the immediate ripple voltage should be maintained between +10 and +30

. Screw terminals +Vs and GND are for power supply wiring.

Note: The wires used should be at least 2 mm

Figure 2-12: ADAM-5510 power wiring

I/O modules wiring

The system uses a plug-in screw terminal block for the interface between an I/O module and field devices. The following information must be considered when connecting electrical devices to I/O modules.

1. The terminal block accepts wires from 0.5 mm 2 to 2.5 mm 2.

2. Always use a continuous length of wire. Do not combine wires to make them longer.

ADAM-5510 2-11

Installation Guidelines

3. Use the shortest possible wire length.

4. Use wire trays for routing where possible.

5. Avoid running wires near high energy wiring.

6. Avoid running input wiring in close proximity to output wiring where possible.

7. Avoid creating sharp bends in the wires.

Its IBM-PC compatible hardware and operating system runs programs written in both assembly and high level languages. Each system can handle up to 4 I/O modules (up to 64 I/O points). The system also provides serial communication ports (RS-232/485), allowing the system to communicate with other devices for versatile applications.

3.2 Major Features

The ADAM-5510 system consists of two major components: the main unit and I/O modules. The main unit includes a CPU card, a power regulator, a 4-slot base, two serial communication ports and a programming port. It has the following major features:

Built-in 80188 CPU and ROM-DOS operating system

ADAM-5510's CPU card includes an 80188 microprocessor. Its

ROM-DOS operating system is an MS-DOS compatible system. It provides all the basic functions of MS-DOS except the BIOS. Users can run standard PC software or application programs written in high level languages under this ROM-DOS environment.

Built-in ROM and RAM disk for programming

The ADAM-5510 has built-in flash ROM and SRAM for file downloading, system operation and data storage. The system provides 170

KB free ROM to allow users to download programs. There is also 192

KB free RAM to provide the memory needed for efficient application operation and file transfer.

Built-in RS-232/485 communication ports

The ADAM-5510 has two serial communication ports to enable the controller to communicate with other devices in your applications.

The COM1 port is dedicated as an RS-232 interface. The COM2 port is dedicated as the RS-485 port. This unique design makes the controller suitable for use in a variety of applications.

Chapter 3

3-way isolation and watchdog timer

Electrical noise can enter a system in many different ways. It may enter through an I/O module, a power supply connection or the communication ground connection. The ADAM-5510 system provides isolation for I/O modules (3000 V connections (2500 V

), communication

), and power connections (3000 V

). The

3-way isolation design prevents ground loops and reduces the effect of electrical noise on the system. It also offers better surge protection to prevent dangerous voltages or spikes from harming your system.

The system also provides a watchdog timer to monitor the microprocessor. It will automatically reset the microprocessor in the

ADAM-5510 system if the system fails.

I/O Modules

4.1 Analog Input Modules

Analog input modules use an A/D converter to convert sensor voltage, current, thermocouple or RTD signals into digital data. The digital data is then translated into engineering units. When prompted by the host computer, the data is sent through a standard RS-485 interface. The analog input modules protect your equipment from ground loops and power surges by providing opto-isolation of the A/

D input and transformer based isolation up to 3,000 V

ADAM-5013 3-channel RTD input module

The ADAM-5013 is a 16-bit, 3-channel RTD input module that features programmable input ranges on all channels. This module is an extremely cost-effective solution for industrial measurement and monitoring applications. Its opto-isolated inputs provide 3,000 V

of isolation between the analog input and the module, protecting the module and peripherals from damage due to high input line voltage.

Note:

Owing to the conversion time required by the A/D converter, the initialization time of each ADAM-5013 module is 5 seconds. Thus the total initialization time will be about 20 seconds if all 4 I/O slots in an

ADAM-5510 main unit contain ADAM-5013 modules.

ADAM-5017 8-channel analog input module

The ADAM-5017 is a 16-bit, 8-channel analog differential input module that provides programmable input ranges on all channels. It accepts millivolt inputs (±150mV, ±500mV), voltage inputs (±1V, ±5V and ±10V) and current input (±20 mA, requires 125 ohms resistor). The module provides data to the host computer in engineering units (mV, V or mA).

This module is an extremely cost-effective solution for industrial measurement and monitoring applications. Its opto-isolated inputs provide 3,000 V

of isolation between the analog input and the module, protecting the module and peripherals from damage due to high input line voltage. Additionally, the module uses analog multiplexers with active overvoltage protection. The active protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. This module can withstand an input voltage surge of 70 Vp-p with ±15 V supplies.

ADAM-5017H 8-channel high speed analog input module

The ADAM-5017H is a 12-bit plus sign bit, 8-channel analog differential input module that provides programmable input ranges on each channel. It accepts millivolt inputs (± 500 mV, 0-500 mV), voltage inputs (±1 V, 0-1 V, ±2.5 V, 0-2.5 V, ±5 V, 0-5 V, ±10 V and 0-10 V) and current inputs (0-20 mA and 4-20 mA; requires a 125 ohms resistor).

The module provides data to the host microprocessor in engineering units (mV, V or mA) or two’s complement format. Its sampling rate depends on the data format received: up to 1,000 Hz (total) in two’s complement or 600 Hz (total) in engineering units. Space is reserved for

125-ohm, 0.1%, 10 ppm resistors (See Figure 4-10). Each input channel has 3000 V

DC of optical isolation between the outside analog input line and the module, protecting the module and peripherals from high input line voltages. Additionally, the module uses analog multiplexers with active overvoltage protection. The active protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. The analog inputs can withstand a constant 70 Vp-p input with ±15 V supplies.

4.3 Analog Output Modules

ADAM-5024 4-channel analog output module

The ADAM-5024 is a 4-channel analog output module. It receives its digital input through the RS-485 interface of the ADAM-5510 system module from the host computer. The format of the data is engineering units. It then uses the D/A converter controlled by the system module to convert the digital data into output signals.

4-16 ADAM-5510

Chapter 4

You can specify slew rates and start up currents through the configuration software. The analog output can also be configured as current or voltage through the software utility. The module protects your equipment from ground loops and power surges by providing optoisolation of the D/A output and transformer based isolation up to 500

Slew rate

The slew rate is defined as the slope indicated the ascending or descending rate per second of the analog output from the present to the required.

4.4 Analog I/O Modules Calibration

Analog input/output modules are calibrated when you receive them.

However, calibration is sometimes required. No screwdriver is necessary because calibration is done in software with calibration parameters stored in the ADAM-5000 analog I/O module‘s onboard EEPROM.

The ADAM-5510 system comes with the ADAM utility software that supports calibration of analog input and analog output. Besides the calibration that is carried out through software, the modules incorporate automatic Zero Calibration and automatic Span Calibration at bootup or reset.

Analog input module calibration

Modules: ADAM-5017, 5017H, 5018

1. Apply power to the ADAM-5510 system that the analog input module is plugged into and let it warm up for about 30 minutes

2. Assure that the module is correctly installed and is properly configured for the input range you want to calibrate. You can do this by using the ADAM utility software. (Refer to Chapter 5)

3. Use a precision voltage source to apply a span calibration voltage to the module‘s V0+ and V0- terminals. (See Tables 4-8 and 4-9 for reference voltages for each range.)

Calibration command). This is also done with the ADAM utility software. (See the “Zero Calibration” option in the Calibration submenu of the ADAM utility software.)

5. Execute the Span Calibration command. This can be done with the ADAM utility software. (See the “Span Calibration” option in the Calibration sub-menu of the ADAM utility software.)

6. Only for ADAM-5018: Execute the CJC (cold junction sensor)

Calibration command. This can be done with the ADAM utility software. (See the “CJC Calibration” option in the Calibration submenu of the ADAM utility software.)

* Note:

Figure 4-18: Cold junction calibration

Zero calibration and span calibration must be completed before CJC calibration. To calibrate CJC, the thermocouple attached to ADAM-5018 and a standard thermometer should be used to measure a standard known temperature, such as the freezing point of pure water. The amount of offset between the

ADAM-5018 and the standard thermometer is then used in the ADAM utility to complete CJC calibration.

ADAM-5510 4-23

I/O Modules

Analog output module calibration

The output current of analog output modules can be calibrated by using a low calibration value and a high calibration value. The analog output modules can be configured for one of two ranges: 0-20 mA and

4-20 mA. Since the low limit of the 0-20 mA range (0 mA) is internally an absolute reference (no power or immeasurably small power), just two levels are needed for calibration: 4 mA and 20 mA.

1. Apply power to the ADAM-5510 system including the analog output module for about 30 minutes.

2. Assure that the module is correctly installed and that its configuration is according to your specifications and that it matches the output range you want to calibrate. You can do this by using the ADAM utility software. (Refer to Chapter 5, Utility

Software)

3. Connect either a 5-digit mA meter or voltmeter with a shunt resistor

(250 ohms, .01 % and 10 ppm) to the screw terminals of the module.

Figure 4-19: Output module calibration

4. Issue the Analog Data Out command to the module with an output value of 4 mA.

ADAM-5510

Chapter 4

5. Check the actual output value at the modules terminals. If this does not equal 4 mA, use the "Trim" option in the "Calibrate"submenu to change the actual output. Trim the module until the mA meter indicates exactly 4 mA, or in case of a voltage meter with shunt resistor, the meter indicates exactly 1 V. (When calibrating for 20 mA using a voltage meter and shunt resistor, the correct voltage should be 5 V.)

6. Issue the 4 mA Calibration command to indicate that the output is calibrated and to store the calibration parameters in the module's

EEPROM.

7. Execute an Analog Data Out command with an output value of

20 mA. The module's output will be approximately 20 mA.

8. Execute the Trim Calibration command as often as necessary until the output current is equal to exactly 20 mA.

9. Execute the 20 mA Calibration command to indicate that the present output is exactly 20 mA. The analog output module will store its calibration parameters in the unit's EEPROM.

4.5 Digital Input/Output Modules

ADAM-5050 16-channel universal digital I/O module

The ADAM-5050 features sixteen digital input/output channels. Each channel can be independently configured to be an input or an output channel by the setting of its DIP switch. The digital outputs are opencollector transistor switches that can be controlled from the ADAM-

5510. The switches can also be used to control solid-state relays, which in turn can control heaters, pumps and power equipment. The

ADAM-5510 can use the module’s digital inputs to determine the state of limit or safety switches, or to receive remote digital signals.

Warning!

A channel may be destroyed if it is subjected to an input signal while it is configured to be an output channel.

Please make sure that the ADAM-5080 counter/frequency module is properly inserted into the compatible main units.

ADAM-5080 4-channel Counter/Frequency Module

With ADAM-5080 4-Channel Counter/Frequency Module, users can select either counter or frequency mode for data output. ADAM-5080 offers users a variety of very flexible and versatile applications such as below:

Counter Mode or Frenquency Mode

If you want to measure the number of input signals for totalizer function, you may use counter mode to measure quantities such as movement and flow quantity. Alternatively, you can also select frequency mode to calculate the instantaneous differential of quantities such as rotating speed, frequency or flow rate, and present them in specific engineering formats.

Up/Down or Bi-direction Function

When operating in counter mode, you can choose either the Up/

Down function or the Bi-direction function for different application purposes. The counter will count up or down according to your applications. This counting function helps users obtain the most accurate data.

Alarm Setting Function

While in counter mode, you can set alarm status--Disable and Latch. If you want to disable it, you can select Disable.If Latch status is

ADAM-5510

Chapter 4 selected, it means the Alarm status will be "latched" whenever the alarm being triggered. Once the alarm status being "latched," it will thereafter stay in that triggered state. Users will have to issue a "Clear

Alarm Status" command to return the "latched" alarm status back to normal. Users can designate the high-limit value and low-limit value to regulate your alarm behavior through the utility program.

Digital Output Mapping

Users can either run the utility program or issue a "Set Alarm Connetion" command to designate a specific digital output module for the alarm signal to be sent through.

Features -- Counter Mode

Up/Down Counting

The Up/Down Counter Function offers two types of counting:

Up Couting (increasingly) and Down Counting (decreasingly).

Up Counting : when C0A+ and C0A- sense any input signals, the counter counts up.

Down Counting : when C0B+ and C0B- sense any input signals, the counter counts down.

On receiving Up and Down signal simultaneously, the counter will not perform each specific counting accordingly, but will remain at the previous counting value, since these simultaneous signals won't have any effect on counting values.

If you need only one type of counting, connect C0A+ and C0A- for Up Counting only; or connect C0B+ and C0B- for Down Counting only.

Bi-direction Counting

For implementing Bi-derection Counting, you need to connect C0B+/

D+ and C0B-/D- to implement the control function for

Up/Down Counting.

ADAM-5510 4-39

Overflow Value

Overflow value is the number of times the counter value exceeds the

Max/Min values you specified. When the counter value exceeds

Maximum value, the overflow value increases; When the counter value goes under Minimum value, the overflow value decreases. Besides, when the counter value runs beyond the range of Max/Min value, it will continue counting from the initial value. Furthermore, if users want to check the counter value to see if it is higher or lower than the Max/

Min value, they can run the "$aaSi7" command to gain a readout of the overflow value.

Getting the Totalizer Value

If users want to get the actual counter value, a formula such as follows can facilitate an easy calculation from the initial counter value, overflow value and current counter value:

V tol =

{|V ini

V min (or

V max)

|+ 1} x |V vf

| + |V ini

- V cur

V tol : totalizer value

V ini : initial counter value

V min : min. couner value = 0 (fixed value)

V max : max. counter value = 2

= 4,294,967,295 (fixed value)

V vf : overflow value

V cur : current counter value

Example:

If the initial value =10, overflow value =4, min. value = 0, current counter value = 3, the totalizer value could be calculated as

totalizer value = {|10 - 0| + 1} x| 4 |+ |10 -3| = 51

Overview

Compatible ADAM-5000 Series Main Units

The ADAM-5090 is a 4-port RS-232 communication module to be implemented with the following Advantech ADAM-5000 series main units:

ADAM-5510 (with library Version V1.10 or above)

ADAM-5511 (with library Version V1.10 or above)

ADAM-5090 4-port RS-232 Communication Module

Bi-direction Communication

The ADAM-5090 is equipped with four RS-232 ports, which makes it especially suitable for bi-direction communication. It can simultaneously read data from other third-party devices such as Bar Code and

PLC as long as these devices are equipped with a RS-232 interface.

Furthermore, the ADAM-5090 can issue commands to control other devices. It is fully integrated with the ADAM-5000, ADAM-5500 and

ADAM-4000 series, and transmits data to each other through the

RS-232 port. The whole integrated system is an intelligent stand-alone system and can connect and issue commands to control devices such as printers and PLCs in remote factory location.

The ADAM-5090 transmits and receives data by polling communication, and each port can receive up to 128 bytes in the FIFO. For continuous data longer than 128 bytes, please refer to Table 4.17 for

Baud Rate setting to avoid data loss.

Programming and Downloading

This chapter explains how to program applications and download programs into the ADAM-5510 system. Additionally, it points out limitations and issues about which you should be aware.

5.1 Programming

The operating system of ADAM-5510 is ROM-DOS, an MS-DOS equivalent system.

It allows users to run application programs written in assembly language as well as high level languages such as C or C++. However, there are limitations when running application programs in the

ADAM-5510. In order to build successful applications, you should keep the following limitations and concerns in mind.

5-2 ADAM-5510

Chapter 5

Mini BIOS functions

The ADAM-5510 provides only two serial communication ports for connecting peripherals, so the mini BIOS of ADAM-5510 only provides 10 function calls. Since the user’s program cannot use other

BIOS function calls, the ADAM-5510 may not work as intended.

Additionally, certain language compilers such as QBASIC directly call BIOS functions that are not executable in ADAM-5510. The

ADAM-5510 mini BIOS function calls are listed in the following table.

Programming and Downloading

Converting program codes

The ADAM-5510 has an 80188 CPU. Therefore, programs downloaded into its flash ROM must first be converted into 80186 or 80188 compatible code, and the floating point operation must be set to emulation mode. For example, if you were to develop your application program in Borland C, you would compile the program as indicated in the screen below.

5-4

Figure 5-1: Converting program codes

Other limitations

1. The ADAM-5510 does not support the standard PC function

“8253”. Therefore, the C language, function call “delay ( )” cannot be used in ADAM-5510 applications.

2. Certain critical files are always kept in flash ROM, such as operating system, BIOS, and monitoring files. The ADAM-5510 provides an additional 170 KB of free ROM space for downloading user applications. An additional free 192 KB of RAM is provided for operation of applications.

ADAM-5510

Chapter 5

Programming the watchdog timer

The ADAM-5510 is equipped with a watchdog timer function that resets the CPU or generates an interrupt if processing comes to a standstill for any reason. This feature increases system reliability in industrial standalone and unmanned environments.

If you decide to use the watchdog timer, you must write a function call to enable it. When the watchdog timer is enabled, it must be cleared by the application program at intervals of less than 1.6

seconds. If it is not cleared at the required time intervals, it will activate and reset the CPU, or generate an NMI (Non-Maskable

Interrupt). You can use a function call in your application program to clear the watchdog timer. At the end of your program, you still need a function call to disable the watchdog timer.

Interrupt types

Three types of interrupts may occur in the ADAM-5510. The following table shows the types of interrupts.

5.2 File Download and Transfer

This section explains how to download application programs from a PC into the ADAM-5510 flash ROM and how to transfer files from a PC into ADAM-5510’s SRAM.

Install utility software on host PC

ADAM-5510 systems come packaged with a utility disk containing the files and directories listed in Chapter 0 Quick Start.

Copy all the files and directories on the utility disk to the specified directory of the host computer's hard drive.

Creating the ALLFILE directory

Application programs are downloaded from a host-PC to the flash

ROM of ADAM-5510 using the ADAM-5510 utility software. The

ADAM-5510 utility software is first installed on a host-PC, and the user must create a new directory, also on the host PC, named

ALLFILE. The user must then load into ALLFILE the following required files: The application program intended for installation in

ADAM-5510; COMMAND.COM; AUTOEXEC.BAT; and

CONFIG.SYS. The user should make certain that AUTOEXEC.BAT

contains the name of the user’s application program so that the application will automatically begin executing whenever the

ADAM-5510 is powered on. When downloading to the ADAM-5510’s flash ROM, the utility software first clears all non-permanent files from the flash ROM, then installs all the files contained in directory ALL-

FILE into the flash ROM. It is therefore critical that all the required files be available in a directory ALLFILE when the utility software tries to access ALLFILE.

ADAM-5510 5-7

Programming and Downloading

Downloading into Flash memory (ADAM-5510s C-drive)

With the ADAM-5510 utility software and the directory ALLFILE, loaded with its proper contents, installed on the host-PC, you can execute the utility software. The main screen, shown in Figure 5-2, will appear when execution begins.

Function Library

6.1 Introduction

User-designed ADAM-5510 application programs make use of

ADAM-5510 library functions. To make the most efficient use of

ADAM-5510’s memory space, the ADAM-5510 function library has been separated into six smaller libraries. Therefore, a user can link only those libraries needed to run his application, and only those libraries will be included in the compiled executable. The smaller the linked libraries, the smaller the compiled executable will be.

Note 1: These function libraries support Borland Turbo C++

3.0 for DOS only.

Quick Start Example

This chapter provides guidelines to what is needed to set up and install a standalone ADAM-5510 control system.

A.1 ADAM-5510 System Requirements

Before you setup an ADAM-5510 system, you can follow the steps to install I/O modules into the ADAM-5510 base.

1. Align the module with the grooves on the top and bottom of the base.

2. Push the unit straight into the base until it is firmly seated in the backplane connector.

3. Push-in the retaining clips at the top and bottom of the unit to secure the module to the base.

The following list gives an overview of what is needed to setup, install and configure an ADAM-5510 environment.

•

ADAM-5510 Main Unit and I/O Modules

•

An IBM PC/AT compatible computer with a standard RS-232 port.

•

Power supply for the ADAM-5510 system (+10 to +30 V

)

•

ADAM-5510 utility diskettes

•

Straight-through and crossover DB-9 cables

Host computer

Any computer that is IBM PC/AT compatible which can run and write programs in an MS-DOS environment and provides an RS-232 communication port to allow users to download programs into the ADAM-

5510.

Power supply

For ease of use in industrial environments, the ADAM-5510 is designed to accept industry standard +24V

unregulated power.

Operation is guaranteed when using any power supply voltage between +10 and +30V

. Power ripples must be limited to 200 mV peak to peak while the voltage in all cases must be maintained between +10 and +30 V

A-2 ADAM-5510

Appendix A

Utility software

A menu-driven utility software disk is provided with ADAM-5510 to help users to download programs to the ADAM-5510. The ADAM-

5510 utility software is executed in an MS-DOS or compatible environment.

A.2 Basic Steps to Install ADAM-5510 System

The following steps explain how to build a successful ADAM-5510 application.

1. Configure the I/O modules that you want to implement in the applications.(See Chapter 4)

2. Write and simulate control logic on host PC.

3. Convert the programs into 80188 or 80186 compatible codes. The floating operation must be set to emulation mode. Then compile the application programs.

4. Transfer program code into the SRAM (D drive) of ADAM-5510.

Then execute it to check if it works as intended.

5. If the program works as intended, download the program into the flash ROM (C drive) of ADAM-5510.

6. Re-power on the ADAM-5510 system to let it standalone operates.

Note: For more details on Steps 2 through 6, see Chapter 5.

COM Port Register

Structure

This appendix gives short description of each of the module’s registers. For more information please refer to the data book for the

STARTECH 16C550 UART chip.

All registers are one byte. Bit 0 is the least significant bit, and bit 7 is the most significant bit. The address of each register is specified as an offset from the port base address (BASE), COM1 is 3F8h and COM2 is 2F8h.

DLAB is the “Divisor Latch Access Bit”, bit 7 of BASE+3.

BASE+0 Receiver buffer register when DLAB=0 and the operation is a read.

BASE+0 Transmitter holding register when DLAB=0 and the operation is write.

BASE+0 Divisor latch bits 0 - 7 when DLAB=1

BASE+1 Divisor latch bits 8-15 when DLAB=1.

The two bytes BASE+0 and BASE+1 together form a 16-bit number, the divisor, which determines the baud rate. Set the divisor as follows:

C.1 Analog Input Formats

The ADAM analog input modules can be configured to transmit data to the host in Engineering Units.

Engineering Units

Data can be represented in Engineering Units by setting bits 0 and 1 of the data format/checksum/integration time parameter to 0.

This format presents data in natural units, such as degrees, volts, millivolts, and milliamps. The Engineering Units format is readily parsed by the majority of computer languages because the total data string length, including sign, digits and decimal point, does not exceed seven characters.

The data format is a plus (+) or minus (-) sign, followed by five decimal digits and a decimal point. The input range which is employed determines the resolution, or the number of decimal places used, as illustrated in the following table:

Input Range

±100 mV, ±150 mV,

Appendix C

Example 1

The input value is -2.65 V and the corresponding analog input module is configured for a range of ±5 V. The response to the Analog Data In command is:

-2.6500(cr)

Example 2

The input value is 305.5ºC. The analog input module is configured for a Type J thermocouple whose range is 0ºC to 760ºC. The response to the Analog Data In command is:

+305.50(cr)

Example 3

The input value is +5.653 V. The analog input module is configured for a range of ±5 V range. When the engineering units format is used, the ADAM Series analog input modules are configured so that they automatically provide an over range capability. The response to the

Analog Data In command in this case is:

Example 3 (Ex3.prj)

This example demonstrates the ability of the ADAM-5510 to communicate with other ADAM products, such as the ADAM-5000/485 system or ADAM-4000 series modules. In this example session, the host PC runs ADAM.EXE and acts as the master, while ADAM-5510 acts as the slave.

Example 4 (Ex4.prj)

This is a modem test example which includes dial, hang-up, autoanswer and set break.

Example 5 (Ex5.prj)

In this example, the user’s RAM, RTC and battery-backup RAM are combined to implement a data logger. This data logger can store the time stamp of each piece of data recorded.

Example 6 (Scanio.prj)

This example scans all slots in an ADAM-5510 and then shows the status of any I/O modules located in the slots. It also demonstrates on/off control of the LEDs on the ADAM-5510, and reads RTC (real time clock) time.

ADAM-5510

Appendix D

Example 7 (Ex7.prj)

ADAM-5017H is a new released AI module in the ADAM-5000 series.

It has a much higher sampling rate than its predecessor, ADAM-5017, as demonstrated by this example.

Example 8 (Ex8.prj)

ADAM-5510 allows users to adjust the size of the battery-backup

SRAM. This example shows the way to use related functions.

Example 9 (Ex9.prj)

The ADAM-5510 utility contains three functions allowing users to access the timer in the ADAM-5510. This example demonstrates these functions.

Example 10 (Ex10.prj)

This example tells user how to read the counter value from the ADAM-

5080, and how to show the data on the screen with ADAM-5510

Utility.

Example 11 (Ex11.prj)

This example provides user a testing tool to verify the ADAM-5090 module. Select any two ports on the module and connected by port-toport cable, the program can detect whether the ports are all right.

Example 12 (Ex12.prj)

The ADAM-5090 allows a direct link to PC. This example provides internal & external loopback test function, and helps user to verify the

ADAM-5090 module and the COM port of PC.

Example 13 (Ex13.prj)

Using ADAM-5090 COM port and ADAM-4520 (RS-232 to RS-422/485 converter) to scan ADAM-4000/5000 series module as remote function. User can also send command to the existing module to get response.

ADAM-5510 D-3

Examples on Utility Diskettes

Example 14 (Ex14.prj)

This example tests the modem device with the basic connecting function. Users can use this program to connect to other device through a modem, and allows other modem to connect to it. It can also call a pager and leave a number message with it.

D-4 ADAM-5510

RS-485 Network

EIA RS-485 is the industry’s most widely used bidirectional, balanced transmission line standard. It is specifically developed for industrial multi-drop systems that should be able to transmit and receive data at high rates or over long distances.

The specifications of the EIA RS-485 protocol are as follows:

•

Maximum line length per segment: 1200 meters (4000 feet)

•

Throughput of 10 Mbaud and beyond -Differential transmission

(balanced lines) with high resistance against noise

•

Maximum 32 nodes per segment

•

Bi-directional master-slave communication over a single set of twisted-pair cables

•

Parallel connected nodes, true multi-drop

ADAM-5510/P31 systems are fully isolated and use just a single set of twisted pair wires to send and receive! Since the nodes are connected in parallel they can be freely disconnected from the host without affecting the functioning of the remaining nodes. An industry standard, shielded twisted pair is preferable due to the high noise ratio of the environment.

When nodes communicate through the network, no sending conflicts can occur since a simple command/response sequence is used. There is always one initiator (with no address) and many slaves (with addresses). In this case, the master is a personal computer that is connected with its serial, RS-232, port to an ADAM RS-232/RS-485 converter. The slaves are the ADAM-5510/P31 systems. When systems are not transmitting data, they are in listen mode. The host computer initiates a command/response sequence with one of the systems. Commands normally contain the address of the module the host wants to communicate with. The system with the matching address carries out the command and sends its response to the host.

E-2 ADAM-5510

Appendix E

E.1 Basic Network Layout

Multi-drop RS-485 implies that there are two main wires in a segment.

The connected systems tap from these two lines with so called drop cables. Thus all connections are parallel and connecting or disconnecting of a node doesn’t affect the network as a whole. Since

ADAM-5510/P31 systems use the RS-485 standard, they can connect and communicate with the host PC. The basic layouts that can be used for an RS-485 network are:

Daisychain

The last module of a segment is a repeater. It is directly connected to the main-wires thereby ending the first segment and starting the next segment. Up to 32 addressable systems can be daisychained . This limitation is a physical one. When using more systems per segment the

IC driver current rapidly decreases, causing communication errors. In total, the network can hold up to 64 addressable systems. The limitation on this number is the two-character hexadecimal address code that can address 64 combinations. The ADAM converter, ADAM repeaters and the host computer are non addressable units and therefore are not included in these numbers.

Star Layout

In this scheme the repeaters are connected to drop-down cables from the main wires of the first segment. A tree structure is the result. This scheme is not recommended when using long lines since it will cause a serious amount of signal distortion due to signal reflections in several line-endings.

E.2 Line Termination

Each discontinuity in impedance causes reflections and distortion.

When a impedance discontinuity occurs in the transmission line the immediate effect is signal reflection. This will lead to signal distortion.

Specially at line ends this mismatch causes problems. To eliminate this discontinuity, terminate the line with a resistor.

The value of the resistor should be a close as possible to the characteristic impedance of the line. Although receiver devices add some resistance to the whole of the transmission line, normally it is sufficient to the resistor impedance should equal the characteristic impedance of the line.

E-6

Example:

Each input of the receivers has a nominal input impedance of 18 k

Ω feeding into a diode transistor- resistor biasing network that is equivalent to an 18 k

Ω

input resistor tied to a common mode voltage of

2.4 V. It is this configuration which provides the large common range of the receiver required for RS-485 systems! (See Figure E-5 below).

ADAM-5510

Appendix E

Figure E-5: Termination resistor locations

Because each input is biased to 2.4 V, the nominal common mode voltage of balanced RS-485 systems, the 18 k

Ω

on the input can be taken as being in series across the input of each individual receiver.

If thirty of these receivers are put closely together at the end of the transmission line, they will tend to react as thirty 36k

Ω

resistors in parallel with the termination resistor. The overall effective resistance will need to be close to the characteristics of the line. The effective parallel receiver resistance R

will therefore be equal to:

= 36 x 10

/30 = 1200

Ω

While the termination receptor R

will equal:

= R

/ [1 - R

]

Thus for a line with a characteristic impedance of 100

Ω

resistor

= 100/[1 - 100/1200] = 110

Ω

Since this value lies within 10% of the line characteristic impedance.

ADAM-5510 E-7

RS-485 Network

Thus as already stated above the line termination resistor R

will normally equal the characteristic impedance Z o

The star connection causes a multitude of these discontinuities since there are several transmission lines and is therefore not recommend.

Note: The recommend method wiring method, that causes a minimum amount of reflection, is daisy chaining where all receivers tapped from one transmission line needs only to be terminated twice.

E.3 RS-485 Data Flow Control

The RS-485 standard uses a single pair of wires to send and receive data. This line sharing requires some method to control the direction of the data flow. RTS (Request To Send) and CTS (Clear To Send) are the most commonly used methods.

E-8

Figure E-6: RS-485 data flow control with RTS

Intelligent RS-485 Control

ADAM-4510 and ADAM-4520 are both equipped with an I/O circuit which can automatically sense the direction of the data flow. No handshaking with the host (like RTS, Request to Send) is necessary to receive data and forward it in the correct direction. You can use any software written for half-duplex RS-232 with an ADAM network without modification. The RS-485 control is completely transparent to the user.

Field Grounding and Shielding Application

Overview

Unfortunately, it’s impossible to finish a system integration task at one time. We always meet some trouble in the field. A communication network or system isn’t stable, induced noise or equipment is damaged or there are storms. However, the most usual issue is just simply improper wiring, ie, grounding and shielding. You know the 80/20 rule in our life: we spend 20% time for 80% work, but 80% time for the last

20% of the work. So is it with system integration: we pay 20% for Wire

/ Cable and 0% for Equipment. However, 80% of reliability depends on

Grounding and Shielding. In other words, we need to invest more in that 20% and work on these two issues to make a highly reliable system.

This application note brings you some concepts about field grounding and shielding. These topics will be illustrated in the following pages.

Appendix F

Figure F-1: Think the EARTH as GROUND.

• Why we think the EARTH as GROUND?

As you know, the EARTH cannot be conductive. However, all buildings lie on, or in, the EARTH. Steel, concrete and associated cables

(such as lighting arresters) and power system were connected to

EARTH. Think of them as resistors. All of those infinite parallel resistors make the EARTH as a single point for reference.

Figure F-2: Grounding Bar.

According to previous description, grounding is one of the most important issues for our system. Just like Frame Ground of the computer, this signal offers a reference point of the electronic circuit inside the computer. If we want to communicate with this computer, both Signal

Ground and Frame Ground should be connected to make a reference point of each other’s electronic circuit. Generally speaking, it is necessary to install an individual grounding bar for each system, such as computer networks, power systems, telecommunication networks, etc. Those individual grounding bars not only provide the individual reference point, but also make the earth a true ground!

1.3 Normal Mode and Common Mode

Appendix F

Figure F-3: Normal mode and Common mode.

Have you ever tried to measure the voltage between a live circuit and a concrete floor? How about the voltage between neutral and a concrete floor? You will get nonsense values. ‘Hot’ and ‘Neutral’ are just relational signals: you will get 110VAC or 220VAC by measuring these signals. Normal mode and common mode just show you that the Frame

Ground is the most important reference signal for all the systems and equipments.

• Neutral-pin is broader than Live-pin, for reducing contact impedance.

1.4 Wire impedance

Appendix F

Figure F-5: The purpose of high voltage transmission

• What’s the purpose of high voltage transmission?

We have all seen high voltage transmission towers. The power plant raises the voltage while generating the power, then a local power station steps down the voltage. What is the purpose of high voltage transmission wires ? According to the energy formula, P = V * I, the current is reduced when the voltage is raised. As you know, each cable has impedance because of the metal it is made of. Referring to Ohm’s

Law, (V = I * R) this decreased current means lower power losses in the wire. So, high voltage lines are for reducing the cost of moving electrical power from one place to another.

What’s Single Point Grounding?

Maybe you have had an unpleasant experience while taking a hot shower in Winter. Someone turns on a hot water faucet somewhere else. You will be impressed with the cold water!

The bottom diagram above shows an example of how devices will influence each other with swift load change. For example, normally we turn on all the four hydrants for testing. When you close the hydrant 3 and hydrant 4, the other two hydrants will get more flow. In other words, the hydrant cannot keep a constant flow rate.

F.2 Shielding

2.1 Cable Shield

Appendix F

Figure F-9: Single isolated cable

• Single isolated cable

The diagram shows the structure of an isolated cable. You see the isolated layer which is spiraled Aluminum foil to cover the wires. This spiraled structure makes a layer for shielding the cables from external noise.

ADAM-5510 F-11

Grounding Reference

Figure F-10: Double isolated cable

F-12

• Double isolated cable

Figure 10 is an example of a double isolated cable. The first isolating layer of spiraled aluminum foil covers the conductors. The second isolation layer is several bare conductors that spiral and cross over the first shield layer. This spiraled structure makes an isolated layer for reducing external noise.

Additionally, follow these tips just for your reference.

•

The shield of a cable cannot be used for signal ground. The shield is designed for carrying noise, so the environment noise will couple and interfere with your system when you use the shield as signal ground.

•

The higher the density of the shield - the better, especially for communication network.

• Use double isolated cable for communication network / AI / AO.

• Both sides of shields should be connected to their frame while inside the device. (for EMI consideration)

•

Don’t strip off too long of plastic cover for soldering.

• Never stripping too much of the plastic cable cover. This is improper and can destroy the characteristics of the Shielded-Twisted-Pair cable. Besides, the bare wire shield easily conducts the noise.

•

Cascade these shields together by soldering. Please refer to following page for further detailed explanation.

• Connect the shield to Frame Ground of DC power supply to force the conducted noise to flow to the frame ground of the DC power supply. (The ‘frame ground’ of the DC power supply should be connected to the system ground)

Don’t strip off too much insulation for soldering. This could change the effectiveness of the Shielded-Twisted-Pair cable and open a path to introduce unwanted noise.

Shield connection (1)

If you break into a cable, you might get in a hurry to achieve your goal.

As in all electronic circuits, a signal will use the path of least resistance. If we make a poor connection between these two cables we will make a poor path for the signal. The noise will try to find another path for easier flow.

F.3 Noise Reduction Techniques

• Isolate noise sources in shielded enclosures.

•

Place sensitive equipment in shielded enclosure and away from computer equipment.

• Use separate grounds between noise sources and signals.

•

Keep ground/signal leads as short as possible.

• Use Twisted and Shielded signal leads.

• Ground shields on one end ONLY while the reference grounds are not the same.

•

Check for stability in communication lines.

• Add another Grounding Bar if necessary.

•

The diameter of power cable must be over 2.0 mm

• Independent grounding is needed for A/I, A/O, and communication network while using a jumper box.

• Use noise reduction filters if necessary. (TVS, etc)

•

You can also refer to FIPS 94 Standard. FIPS 94 recommends that the computer system should be placed closer to its power source to eliminate load-induced common mode noise.
