• Unregulated +10V dc ~ +30V dc.

• Power reverse protection, Over-voltage brown-out protection

System:

• Dual watchdog inside, power-on start value and safe value for host failure

• Operating temperature: -25 to 75ºC (14 to 185ºF)

• Storage temperature: -25 to 80ºC (-13 to 185ºF)

• Humidity: 5 to 95%, non-condensing


1.4 The 7000 Series System Network for Bus Type

• Multiple Baud Rate

• Multiple Data Format


Conventional Two-Wire RS-485 Network: The conventional two-wire RS-

485 network uses a DIP SWITCH selectable converter to convert host

RS-232 or USB signals to a two-wire RS-485 signal. The baud rate and data format must be set to a fixed value for the whole network. For example, the user can choose baud rate=9600 and data format=10 bit per character. This limitation is inconvenient for some real world applications.

The 7000 series, Adam 4000 series, Nudam 6000 series and

DATAFORTH 9B series all use a 10-bit format. Some conventional PLCs use an 11-bit data format and some weight scale equipment uses 12-bit. If the host-PC needs to send commands to remote modules, PLCs and weight scale equipment, one possibility is to use three independent twowire RS-485 networks. However, this may increase system cost and reduce system reliability.

Another option for real world applications is to use many modules in the same two-wire RS-485 network. Each module must communicate at the same baud rate in a conventional system. Some module may be very close to the host-PC and will be able to communicate at a higher baud rate. Other modules may be farther away from the host-PC and will communicate at a lower baud rate. Since only one speed is valid in an

RS-485 network, the higher speed modules should be forced to communicate at a lower speed baud rate. In other words, the performance of the entire system must be decreased.

The 7000 Series RS-485 Network: The 7000 RS-485 network is the most powerful and flexible two-wire RS-485 networks in the world. It is a multiple baud rate and multiple data format network system. That is to say, all the remote modules mentioned above, PLCs and weight scale equipment share the same RS-485 network. The 7520, RS-232 to RS-

485 converter, equips a “Self Tuner” inside, therefore it can detect the baud rate and data format automatically and control the direction of the

RS-485 network precisely. Therefore the user can connect all this equipment to the same RS-485 network. This method will greatly reduce system cost and increase reliability.

2.8 How to select 7520 / 7520R

The 7520R is exactly the same as 7520 except for the isolation site.

The isolation site of the 7520 is located in the RS-232 interface circuit, but the isolation site of the 7520R is located in the RS-485 interface circuit. That is to say, the power input and RS-485 interface is common ground for the 7520 but the power input and RS-232 interface is only common ground for the 7520R as follows:

7520 7520R

Isolation site RS-485 site

Power ground

Common ground

RS-232 site Isolation site

Common ground

Applications Most applications. For RS-232 type PLC networking


Note: the power ground of q7000 and rRS-485 is

common ground.

This is the same for

Adam 4000, Nudam 6000 and

DATAFORTH 9B series modules.

In most applications, the p7520 are used to convert the oRS-232 signal to rRS-485 network. Normally the p7520 does not use the same DC power ground as the nHost PC/PLC, and the isolation site is in the RS-232 section.

Therefore the nHost PC/PLC is isolated from rRS-485 network. That is to say, if there is any high voltage transient on rRS-485 network, the nHost PC/PLC will be free from damage.

WARNING!! ERROR CONDITION 1: if the p7520 are replaced by p7520R and the p7520R uses the same DC power ground with q7000. In this situation,

(1)

The nHost PC/PLC is common ground with oRS-232

(2)

The oRS-232 is common ground with power ground of p7520R

(3)

The power ground of p7520R is common ground with power ground of q7000

(4)

The power ground of q7000 is common ground with rRS-485

Therefore the nHost PC/PLC is common ground with rRS-485 network.

That is to say, there is no isolation between nHost PC/PLC and rRS-485 network. The nHost PC/PLC may be damaged if there is high voltage transient on rRS-485 network.


WARNING!! ERROR CONDITION 2: if the p7520 uses the same DC power ground with nHost PC/PLC (for example, nHost PC/PLC provide non-isolated DC power source to p7520). In this situation,

(1)

The nHost PC/PLC is common ground with power ground of p7520

(2)

The power ground of p7520 is common ground with rRS-485

Therefore the nHost PC/PLC is common ground with rRS-485 network.

That is to say, there is no isolation between nHost PC/PLC and rRS-485 network. So the nHost PC/PLC may be damaged if there is high voltage transient on rRS-485 network.

OK CONDITION: If the DC power ground of p7520 or p7520R is not common to any module, the nHost PC/PLC will be isolated from rRS-485 network in all conditions. only. The 24V DC output of the PWR-24 is isolated from its AC input. If the p7520 or p7520R is connected to the PWR-24, this PWR-24 cannot connect to the other module. Normally the nHost PC/PLC uses a switching power and the DC output of this power supply is also isolated from its AC input. Therefore the DC power ground of p7520 or p7520R is isolated from nHost PC/PLC.

Therefore, the nHost PC/PLC is isolated from rRS-485 network in all condition.

The power adapter PWR-24 is designed for single 7000 series modules nHost PC/PLC is isolated from rRS-485 network for p7520 or p7520R in all condition


The 7520R is designed for PLC networking. During normal conditions, the PLC system will have a stable DC-24V power source. The user may use this power source to s7520R(configuration A). When using t7520, the user must use another power source, uPWR-24

(configuration B).

The isolation feature is very important in real world applications, therefore the user should pay attention when selecting the correct module. If the wrong module is selected, the isolation will be removed but the module will still function OK. This may cause unexpected damaged by high-energy transients on an RS-485 network.

USB series: I-7560 / I-7561 / I-7563

What is USB?

USB, or Universal Serial Bus is a connectivity specification developed by computer and telecommunication industry members for attaching peripherals to computers.

USB is designed to free all the troubles when installing external peripherals. It eliminates the hassle to open computer case for installing cards needed for certain devices.

It is designed to meet Microsoft Plug and Play (PnP) specification, meaning users can install, and hot-swap devices without long installation procedures and reboots.

The I-756x USB to RS-232 or RS-485 or RS-422 converter are your smart and convenient accessory for connecting RS-232 serial devices to your

USB-equipped Windows host computer. It provides a bridge connection with a standard DB 9-pin male serial port connector in one end and a standard Type-A USB plug connector on the other end. You simply attach the serial device onto the serial port of the cable and plug the USB connector into your PC USB port. It allows a simple and easy way of adding serial connections to your PC without having to go thru inserting a serial card and traditional port configuration.

4. I-7551 : RS-232 to RS-232 Converter


Introduction

The I-7551 Photo coupler provides a complete full-duplex (including control signal) electrical isolation channel between two RS-232 devices.

This isolation is an important consideration if a system uses different power sources, has noisy signals or must operate at different ground potentials.

The I-7551 has the option of reconfiguring which control signal is used. CTS can be selected instead of DSR and RTS instead of DTR.

The I-7551 incorporates two DC-to-DC converters; the isolation site of I-7551 is located in the input and output interface circuit. In other words, I-7551 is three- way isolation RS-232-to-

RS-232 converter.

• Power consumption: 2.2W(Max)

• Each channel on the hub is driven by it's own RS-485 driver.

• Each channel maximum line length about of 4000 ft.


5.4.2 System Network Configuration:





5.5 Basic Wire Connections for I-7510

(1)

Extends RS-485 network if the path is over 4000 ft or 1.2 Km

(2)

Extends RS-485 network if connecting over 256 modules

(3)

Cuts a long RS-485 path into several isolated short RS-485 paths for protection


6. 7000 RS-485 Networking

6.1 Standard/Isolation Configuration

Daisy-Chain Configuration.

The Host PC/PLC will send out a command string from its RS-232 port. The s7520 will convert these RS-232 signals into a RS-485 signal and isolate the host from qRS-485 network.

The 7000 series modules, including D/I, D/O, A/D, D/A,

Timer/Counter and MMI modules, will be directly connected to qRS-485.

These 7000 series modules can connect a max. Of 256 modules to the qRS-485 network without a repeater, the 7510. That it to say, there can be 256 modules from n7xxx to o7xxx. If there are over 256 modules, the repeater 7510 must be added to extend the qRS-485 to rRS-485. Then there can be another 256 modules connected to the rRS-485 network.

This is the first function of the 7510.

The module address can be changed from 00 to FF a total of 256 max. Therefore there are maxes. Of 256 modules in one RS-485 network if all the modules communicate with the same speed.

(1)

Because the 7000 can communicate with different baud rates in the same RS-485 network, the n7xxx, o7xxx and p7xxx can be communicated to HOST PC/PLC with a different baud rate.

(2)

The 7000 series can be programmed to 1200, 2400, 4800, 9600,

19200, 38400, 57600, 115200,a total of 8 different speed.

(3)

The 7000 modules can share the same module address if their baud rates are different. For example, n7xxx=module address 01, baud rate=1200


o7xxx=module address 01, baud rate=9600 p7xxx=module address 01, baud rate=115200

These three modules can share the same RS-485 network, generated by s7520.

(4) Therefore there is 256*8=2048 modules max. In one RS-485 network with a repeater (7510).

The “search function” given in DCON_DOS can search for all these

2048 modules in one RS-485 network. Refer to “DCON_DOS.pdf” for completely source listing of “search function”.

When the RS-485 network is over 4000 ft or 1.2Km, the RS-485 repeater (7510) must be added to extend the RS-485 network. For example, if the qRS-485 is over 4000 ft or 1.2 Km, the t7510 must be added to extend qRS-485 to rRS-485. And if the rRS-485 is too long, the user should use another 7510 to extend another RS-485 network. This is the second function of 7510.

The power ground of the 7000 series is common ground to the RS-

485 network. This feature is the same as the Adam 4000, Nudam 6000 and DATAFORTH 9B series. Therefore all the modules in the same RS-

485 network are common ground. For example, the all modules between n7xxx and o7xxx share the same qRS-485 network and all are common ground. The qRS-485 length can be up to 4000 ft or 1.2 km, this is a very long path. This long path makes the RS-485 network very susceptible to network noise by high energy transient in this environment. If this noise is too great, all the modules in the RS-485 network may be damaged simultaneously. This is highly possible and occurs often in real world applications. It is strongly recommended to add another isolation repeater, the 7510, to break the long path RS-485 network into several short RS-

485 networks to avoid all the modules being damaged at the same time.

This is the third function of 7510.


For example, the q7510, s7510 are used to isolate local modules from nRS-485 network. If there is high energy transient on nRS-485 network, all the local modules will be safe.

Isolation Configuration (Strongly Recommended):

If the RS-485 network is not over 100 meters, the terminated resistors are not needed. However, it may be necessary to insert two terminated resistors at both end of the RS-485 segment. It is not easy to calculate the value of a terminator resistor. The best way to do this is to use an oscilloscope to check the RS-485 signal directly. If the impedance match of RS-485 network is OK, the oscilloscope will show a very nice square wave. If these square wave signals are distorted, the user will need to insert two terminators at both end of the RS-485 segment.

OK

Resistor value of

Resistor value of terminator is too small terminator is too big


It is recommended to use the “trial and error” rule. The trial and error rules are given as follows:

(1)

If the length of RS-485 is about 1.2 Km, try 330

Ω first

(2)

Run TEST.EXE of DCON_DOS

Select function_5, run continuously for at least 8 hours to make sure communication is OK.

(3)

If function_5 finds many communication errors, use an oscilloscope to check the waveform. The waveform will tell you whether the terminator is too small or too big. Then adjust your terminator and run TEST.EXE again.

(4)

If the correct terminators are found, run the TEST.EXE continuously for at least 8 hours to make sure there are no communication errors.

The function_5 of TEST.EXE, given in DCON_DOS, will automatically read “testing command” from TEST.DAT and continuously perform “sendreceive-testing”. It will continuously test and record all testing results.

Therefore this function is especially designed for RS-485 network stability evaluation. If you run this function_5 continuously for 8 hours and find no check errors, this means that your RS-485 network is very stable. Also this means that your terminators match well now.

NOTE 1: The value of the terminator depends on the RS-485 wire used. If the RS-485 path is very long, don’t use a cheaper wire. It is recommended to select a high quality wire such as the Belden 1583A.

NOTE 2: The terminator is different for various applications.

Therefore we can’t provide a terminator with the 7520 or the 7510. The user must choose the correct terminator by them self. It is recommended to use a carbon, 1/4w resistor.


These PLCs can be used at different baud rates & different configurations. For example,

PLC-1=1 start + 7 data + 1 stop=9-bit/byte, baud rate=1200

PLC-n=1 start + 8 data + 1 parity + 1 stop=11-bit/byte, baud rate=9600

PLC-m=1 start + 8 data + 1 parity + 2 stop=12-bit/byte, baud rate=115200

OMRON CQM1 = 1 start + 7 data + 1 even parity + 2 stop =11-bit/byte

OMRON C200 = 1 start + 7 data + 1 even parity + 2 stop = 11-bit/byte

The n7520 can be the 7520 or 7520R, refer to Sec. 2.5 for details.

The p7520R, q7520R, r7520R can be the 7520 or 7520R, refer to

Sec. 2.5 for details. In this configuration, the tPLC1, uPLCn, vPLCm provides DC power to p7520R, q7520R, r7520R. This is the cheapest to the 3000V high isolation. The user should not replace the 7520R, p, q, r, with the 7520.

Refer to “DCON_DOS.pdf” for PLC networking software details.


6.3 PC Networking Applications:

(For this application, we recommend to use i-7520U to replace the i-7520)

Every remote-PC must have a unique address. This unique address is similar to the module address of the 7000 series. We call it a “slave-PC address”. The module address of the 7000 series is limited to 256, but the slave-PC address is unlimited. The user can connect thousands of PCs in one RS-485 network by using a repeater, the

7510.

Refer to “DCON_DOS.pdf” for software details. Using this software, the host-PC can send out commands to remote-PCs, just like sending commands to the 7000 series modules. The remote-PC will receive these commands and execute the command if the destination addresses matches it’s local address.

These remote-PC and 7000 series modules can use the same RS-485 network.

The host-PC can send out the 7000 series commands and send out PC-networking commands at different times. The modules and remote-PCs will receive their command respectively. This makes the network very low cost, with high flexibility and reliability. This unique feature is not found elsewhere in the world.


6.4 RS-232 Devices Network

(For this application, we recommend to use i-7520U to replace the i-7520)

Some RS-232 devices can be connected to the 7000 RS-485 network very easily, just like the PC or PLC introduced in Sec 6.2 and Sec.

6.3. These RS-232 devices must adhere to 3 rules given as follows:

Rule 1: cannot send out the RS-232 signal in normal, operating state.

Rule 2: every device has a unique device address

Rule 3: will not send out a RS-232 signal if the destination address does not match with the device address

The software for RS-232 device networking and PLC networking is very similar. The only difference is the command format. The command format of PLC is always different for different manufacturers. Refer to “DCON_DOS.pdf” for software details.
