Set MSD switch to this number's corresponding HEX digit. Use a screwdriver to rotate these switches to set a unique valid address from 0 to 125. MSD x16 HEX LSD DEC x1 HEX 1 2 If the switches are set to a valid address from 0-125, then the switch setting determines the slave address and the Set Slave Address software command will be rejected. 0 0 0 0 16 1 1 1 32 2 2 2 48 3 3 3 64 4 4 4 80 5 5 5 96 6 6 6 112 128 144 160 176 192 208 224 240 7 8 9 A B C D E F 7 8 9 10 11 12 13 14 15 7 8 9 A B C D E F 2. Determine the DECimal remainder and set the LSD switch to its corresponding HEX digit. If these switches are instead set to 126 (7EH) upon powerup, the unit will retrieve its address from the internal EEPROM, which is modified via the Set Slave Address command. If these switches are set to 255 (FFH) upon power-up, this will return the address in EEPROM to 126 (7EH). The address stored in the internal EEPROM is modified via the Set Slave Address command. If the address switches are set to 126 (or 126 to 254) upon power-up, the module will retrieve the last address stored within its EEPROM (126 from the factory). With both the internal EEPROM and external switch addresses set to 126, the unit will await the Set Slave Address command after power-up, before proceeding to the parameterization state (address 126 cannot be used in data exchange mode and is reserved for commissioning purpose only). You must use the Set Slave Address command to change the internal (EEPROM) address following power-up in order to proceed. However, if the switches are set to an address less than 126 upon power-up, then the switches determine the slave address and the EEPROM setting is ignored. You can later restore the internal EEPROM setting to 126 by powering the unit up with the address switches set to 255 (FF). You would then power the unit up again with these switches set to 126 in order to place the unit in commissioning mode.

Additionally, ground the ProfiBus cable as shown below. Earth Ground The ground connections noted are recommended for best results. If sensors are already grounded, use caution and avoid making additional ground connections which could create ground loops. Warning: To comply with safety and performance standards, use shielded cable and connect earth ground as noted. Failure to use good wiring and grounding practices may be unsafe and hurt performance. The plastic module housing does not require earth ground. PROFIBUS WIRING AND GROUND PROFIBUS CONNECTOR GROUNDING: 1. Always connect the cable shield to earth ground at both ends as shown. 2. If the field device does not include an earth ground screw, it may be necessary to strip the cable insulation near the field device and clamp the cable shield to a local grounding bar or surface as shown. PROFIBUS FIELD DEVICE THE SHIELD IS COMMON TO THE HOUSING (FOR METAL ENCLOSURES). OUT GROUND CLAMP ACROMAG MODULES: The metal shroud of the DB9 ProfiBus connector on Acromag modules is common to pin 1 of the DB9 connector (SHIELD). This is also common to the cable shield which must be earth grounded. Acromag modules are enclosed in plastic and do not provide a dedicated earth ground screw. As such, a local earth ground connection to the cable shield must be made as shown above. R on off CABLE SHIELD EARTH GROUND SCREW ON EQUIPMENT (WHEN AVAILABLE) INP NOTE: If a potential difference exists between earth grounding points, an equalization current can flow through the cable shield when connected at both ends. In this case, it may be necessary to install an additional potential equalization line between field locations to minimize this current as shown here. CABLE SHIELD EQUIPOTENTIAL BONDING STRIP (IF NECESSARY--SEE NOTE) PROFIBUS CABLE GROUND CLAMP THE SHIELD IS COMMON TO THE HOUSING (FOR METAL ENCLOSURES).

During this period, the green “Run” LED will flash for a moment. If the diagnostics complete OK, the “Run” LED will stop flashing after a few seconds and remain ON. This indicates the unit is operating normally. Once the unit has passed through the initialization, parameterization, and configuration states, and is in data exchange mode, the yellow BUS LED will be ON. If the BUS LED is OFF and the unit is connected to the network, then this is indicative of an initialization problem. Top Four Common ProfiBus Problems Troubleshooting Tools Follow the ProfiBus installation guidelines. Use the recommended cable and connectors of the standard. Verify that none of the wires are broken or shorted. Don’t mix the A & B lines. Use green wire for A and red wire for B. Do not exceed the recommended segment length for the baud rate. Make sure that there are no more than 32 RS-485 devices per segment (including the master device and the repeater). Check for proper termination of all copper-wire network segments (an RS-485 segment must have a termination resistor at both ends of the segment only). All activated terminations must be powered all the time. If this is not possible, then consider using an active-termination box. Check whether the station address is set to the correct value. If your network connects between buildings or runs through hazardous environments, consider the use of fiber-optics. Avoid drop lines and keep their length within the specified maximum. For T-drops, consider using repeaters and active-bus terminations. 1. Incorrect slave address set at the slave. 2. ProfiBus connector between the master and slave has its termination switch turned ON. 3. Incorrect module configuration sent to slave. 4. Configuration is based on outdated GSD file information. There are several models of handheld devices on the market that simplify the installation and troubleshooting of ProfiBus networks. The more sophisticated units include LCD displays that read out errors directly. Two of these of these devices are referenced below: Hand-Held ProfiBus Network Maintenance Tools Manufacturer Part Number Special Features Siemens BT 200 Primarily a Cable Tester Comsoft NetTest II Set Includes DP Mono-Master 4000-7-06C-J Functionality In general, these devices can be used to check the network wiring before devices are connected to the bus and are often used to indicate: Whether the A and B lines have been switched. Whether a short exists between the A & B lines and shield. The occurrence of a wire-break in the A or B line, or shield line. Improper termination. _______________________________________________________________________________________ Acromag, Inc.

They may include the following functions: 9 Troubleshooting Tools Create a list of all stations connected to a network (useful for identifying missing or “offline” devices). Can test individual stations and help identify duplicate addresses. Measure the distance along a network segment to verify whether it complies with the Profibus requirements for distance and data rate. Detect signal reflections along the network, useful for locating bus line interruptions and discontinuities. Acromag strongly suggests the use of these tools for building and maintaining ProfiBus networks. Note that Profichip also offers a Profibus connector (PA003100) that includes 4 network diagnostic LED’s that may be helpful in trouble-shooting your network (see table below). The standard 9-pin ProfiBus connectors with integrated termination resistors are also helpful in troubleshooting segments of the network. In most of these connectors, when the termination resistors are switched ON, the outgoing portion of the connector is disconnected. As such, you can selectively disable segments of the network until you find the branch that is causing the problem. For example, if your handheld unit is connected to the beginning of a network and indicates a wire break, you can selectively switch off portions of the network and recheck your handheld unit to help pin point the portion of the network that is causing the problem. Below are some ProfiBus connectors that we recommend: Preferred Bus Connectors Manufacturer Part Number Siemens 6ES7972-0BA12-0XA0 Siemens 6ES7972-0BB12-0XA0 Profichip PA003100 Using Connectors To Troubleshoot Special Features Switchable Termination Adds PB Interface (Piggy Back DB9 For Diagnostic Connection) Adds PB Interface and Four Diagnostic LED’s For TroubleShooting. ProfiBus includes a rich diagnostic function that can be used to troubleshoot ProfiBus devices. This function contains 6 bytes of standard diagnostic information, plus up to an additional 238 bytes of device specific diagnostic information. Most configuration tools support this command and can read the diagnostic information from the Profibus device.

Acromag’s Application Engineers can provide further technical assistance if required. Complete repair services are also available from Acromag. SYMPTOM Yellow BUS LED does not light. Cannot communicate. POSSIBLE CAUSE Initialization Problem. LED ON if module in data exchange state. Both the internal EEPROM and external address switches are set to an address of 126. Is power ON at the module and/or RS485 converter? Is address correct? Is the termination switch of the Profibus connector at the prior node turned on? Yellow BUS LED turned OFF. Continuous flashing green RUN LED. Many Communication Errors. Communication Halted. Internal firmware problem. Missing Termination Resistors? Is baud rate too high for distance? CALIBRATION IMPORTANT: This module has already been calibrated at the factory and recalibration is not normally required, except as necessary to correct for long term component aging, or to satisfy your company’s maintenance requirements. Do not attempt to recalibrate this module unless absolutely required, as miscalibration will negatively affect the module’s performance. POSSIBLE FIX Check Station Address. Is GSD file correct. Check for wiring error. Module is awaiting Set Slave Address command in order to complete initialization. Alternately, set switches from 0-125 and re-power. Check power. Is green RUN LED ON? Check address settings at the slave. Switch Termination on only at the ends of the network. With termination switch on, the outgoing connections are disconnected from the network chain. Cycle power to reset unit. Investigate grounding. Return the module for service. Termination resistors must be placed only at both ends of a network or network segment. Maximum distance is limited below 1200 meters as baud rate is increased above 93.75Kbps (see Table). The following table gives the calibration values for these models. These are the input signals required to calibrate the range endpoints. Your success in recalibrating the input will depend upon the accuracy and precision of your signal source. Note that on the 963PB-2012, the 4-20mA range is a sub-range of the 0-20mA range and is automatically calibrated at the same time. If calibration is required, all three ranges of both models should be done. INPUT RANGE ZERO Cal (Cal Lo) 963PB-2012 (12 Current Inputs) 0 to 20mA & 4 to 20mA 1.0mA 0 to 11.17mA 1.0mA 0 to 1mA 0.25mA 964PB-2012 (12 Voltage Inputs) -10V to +10V DC -10.0V -5V to +5V DC -5.0V -1V to +1V DC -1.0V FS Cal (Cal Hi) 20.0mA 11.17mA 1.00mA +10.0V +5.0V +1.0V _______________________________________________________________________________________ Acromag, Inc.

The normal data exchange definition supports 12 input words (your measured value). A second calibration definition supports 12 input and 12 output words. The master software will allow you to choose which mode the slave will assume—Input Mode or Configuration Mode. The method used to transfer information between the master and slave will vary widely between systems. The steps below represent the minimum steps necessary to accomplish software calibration. If you choose to perform calibration and select Configuration Mode, the master will download the 12I/12O configuration during the startup sequence, and the module may then be calibrated as follows: 11 CALIBRATION Note: For best results, be sure to use a precision signal source capable of reproducing the nominal endpoint signals at least as accurate as the module itself (better than ±0.1% of span). Always allow the module to warm up a few minutes prior to calibration. 1. With your master software, select the “Configuration Mode” from the GSD file when setting up the master to communicate with the module. 2. With user parameterization bytes 0-2, set the ranges that are to be calibrated. 3. Apply the zero calibration signal (see table below) to the input to be calibrated and allow the input to settle a few seconds. 4. Write FFH into the low-order byte of the channel’s output word several times (to ensure transmission). In Configuration Mode, the module will automatically calibrate the channel’s zero value when FFH is detected. Then write 00H into the low-order byte to complete zero calibration. 5. Apply the full-scale calibration signal (CalHi, see table) to the input to be calibrated and allow the input to settle a few seconds. 6. Write FFH into the high-order byte of the channel’s output word several times (to ensure transmission). In Configuration Mode, the module will automatically calibrate the channel’s full-scale value when FFH is detected. Then write 00H into the high-order byte to complete full-scale calibration. 7. Repeat steps 3-6 for the other channels of the same range. 8. With user parameterization bytes 0-2, select the next range to be calibrated. Note (963PB): The 4-20mA range is calibrated when the 0-20mA range is calibrated and is not calibrated separately. All other ranges are calibrated separately. 9. Repeat steps 3-7 for all channels of this range. 10. Repeat steps 8-9 until all input ranges have been calibrated. 11. When finished calibrating, use the master software to return the module to the normal “Input Mode” to prevent miscalibration. After completing calibration, the module should be reconfigured as required and placed in the normal “Input Mode” configuration (I/O configuration is 12 input words only). In general, your software allows you to select the normal “Input Mode” configuration, and the slave will then be taken off-line by the master and reconfigured. If reconfiguration is successful, the slave module will pass to the data exchange state with a normal I/O configuration. _______________________________________________________________________________________ Acromag, Inc.

Input channels are arranged in three groups (ports) of four inputs, which are driven to separate channels of the A/D. Because each port feeds a different A/D channel, each channel of the port must have the same input range. However, different ports may use different input ranges. Current inputs sink into a precision 50Ω resistor (963PB). Voltage inputs feed precision 10:1 resistive dividers (964PB). A multiplexer is used to connect the voltage from each channel of a port to a channel of the A/D converter (one A/D channel per port). The A/D converter then applies gain to the signal, converts the analog signal to digital, and then digitally filters the signal. The digitized signal is then transmitted serially to the microcontroller. The microcontroller completes the transfer function according to the input type and range per its embedded program. Configuration and calibration parameters are stored in non-volatile memory integrated within the microcontroller. These modules implement the ProfiBus protocol via an industry-standard SPC3 ASIC from Siemens. This ASIC acts like a RAM or UART chip to the internal microcontroller and completely handles the requirements of the protocol standard. The ASIC will transfer network data to the microcontroller and automatically provide the response to the bus. The ASIC handles the ProfiBus protocol and communicates with the network via an optically isolated RS485 transceiver. A wide input switching regulator (isolated flyback) provides isolated power to the I/O circuit and the RS485 port. Refer to the simplified schematic shown below to gain a better understanding of the circuit. +6V PORT 1 IN00 IN01 RTN IN02 IN03 RTN 963/964PB SIMPLIFIED SCHEMATIC CH0 CH1 ISOLATED RS485 CH2 CH3 M U X IN06 IN07 RTN -6V IN10 IN11 RTN BUS LED +5V +5V RTS A/D CONVERTER PROFIBUS SPC3 SLAVE ASIC MICRO CONTROLLER RS485 PROFIBUS TRANSCEIVER CH4 AIN2 CH5 CH6 CH7 M U X 4 DB9 SHLD 4 N E T W O R K ADDRESS BUFFER AIN3 EF 0 1 2 D 3 C 4 B 5 A 6 987 EF 0 1 2 D 3 C 4 B 5 A 6 987 ISOLATED INPUT POWER +6V -6V PORT 3 IN08 IN09 RTN PWR LED +5V AIN1 +6V PORT 2 IN04 IN05 RTN HOW IT WORKS +5V 1.6V BIAS FOR BIPOLAR CH8 CH9 CH10 CH11 M U X 12-36VDC ISOLATED SECONDARIES NETWORK POWER ISOLATED FLYBACK SWITCHER 5V 5V DC+ DC- P O W E R INPUT/LOGIC POWER ALL INPUTS OF A PORT MUST BE SAME RANGE -6V NEG VOLTAGE CONVERTER +6V -6V _______________________________________________________________________________________ Acromag, Inc.

Units are DCpowered with reverse polarity protection. Analog inputs (as a group), network, and power are isolated from each other. Input channels share common. Non-volatile reprogrammable memory in the module stores configuration and calibration information. Model Numbers 963PB-2012 (Current) 964PB-2012 (Voltage) The ProfiBus model prefix “900” denotes the Series 900. The “PB” suffix denotes ProfiBus. Select 963PB for current input, and 964PB for voltage input. The four digit suffix of this model number represents the following options, respectively: “2” = ProfiBus DP; “0” = Default; “12” = 12 Channels. Analog Inputs Twelve analog input channels with a common (RTN) connection for DC current or voltage applications only. The unit must be wired and configured for the intended input type and range (see Connections Section for details). The unit can be configured to accept one of several input ranges described below. DC Current (963PB Only): Configurable for 0 to 20mA, 4-20mA, 011.17mA, and 0-1mA DC nominal input ranges. A precision 49.9 current sink resistor converts the input current to a voltage that is processed by the A/D converter. An optional external sensor is required to monitor AC current signals (Acromag Model 5020-350). This sensor generates a DC milliampere signal of 0 to 11.17mA for the module (see Table 1 below for scaling to AC current). Current Input Reference Test Conditions: 4 to 20mA current input; Ambient Temperature = 25C. Input Overvoltage Protection: Bipolar Transient Voltage Suppressers (TVS), 5.6V clamp level typical. Optional AC Current Sensor (Model 5020-350, For Use With 961PB/963PB): This sensor is a toroidal instrument transformer that converts a sinusoidal 50-60Hz AC current signal into a low level DC milliampere signal of 0 to 11.17mA. The input AC current range is a function of the number of turns placed through the toroid as shown in Table 1 below. This sensor is isolated and requires no calibration or adjustment. When used with a 961PB/963PB module, it provides redundant input isolation and may facilitate input-to-input isolation of this six channel unit.

Stop Bits: One. Communication Distance: Up to 1200 meters without a repeater. Address: Set via two rotary hexadecimal switches adjacent to the power terminals, or alternately via the Set Slave Address command. Valid setting is 0-125 (7 bits). Address 126 (7EH) is the default factory address and is reserved for commissioning purposes only. Address 127 (7FH) is reserved by the software as a global address for broadcast messages. If the address switches are set to 126 upon power-up (or 126 to 254), then the unit will retrieve its address from its internal EEPROM rather than the switches. The internal EEPROM setting is modified via the Set Slave Address command. Powering up with switches set to 255 (FFH) will cause the internal EEPROM setting to revert back to 126 (7EH), which may be used to recommission the module. If both the internal EEPROM address and the switches are set to 126 upon power-up (this is the initial state from the factory), the module will await the Set Slave Address command before completing initialization and assuming the data exchange mode. IMPORTANT (Address Setting): The internal EEPROM address setting and external switch setting is 126 from the factory. As such, the module will await the Set Slave Address command following power-up and will not proceed to exchange data, unless the external switches are instead set to an address from 0-125, or the internal setting is changed to an address from 0-125 via the Set Slave Address command. Maximum Message Size: Up to 32 bytes recommended, extendable up to 244 bytes of data/node/message, plus 11 bytes of overhead (frame). ProfiBus Character: 11 bits (1 start bit + 8 data bits + 1 even parity bit + 1 stop bit). Applies to all bytes, including frame bytes. Bus Idle State: “1” (a start bit causes line to go to “0”). An idle state of at least 33 Tbits (sync-time) must be provided between messages. Note: 1Tbit at 12Mbaud = 1/12000000bit/sec = 83nsec. Ident_Number: 06F4 Hex (963PB-2012), 06F5 Hex (964PB-2012).

Data Types Percentage (This Model) Temperature Discrete Default NA 00H 19 Controls & Indicators Module Specific Parameters This model includes four user parameterization bytes (User_Prm_Data) defined as shown at left. 00H 00H 00H Note that channels of the same port (every group of 4 channels) share the same configuration, but the configuration may vary port-toport. All parameterization bytes take effect immediately. This model does not include any user defined diagnostic data (Ext_Diag_Data). 00H Description A 16-bit signed integer value with resolution of 0.005%/lsb. 20000 is used to represent 100%. For example, -100%, 0% and +100% are represented by decimal values –20000, 0, and 20000, respectively. The full range is –163.84% (-32768 decimal) to +163.835% (+32767 decimal). A 16-bit signed integer value with resolution of 0.1C/lsb. For example, a value of 12059 is equivalent to 1205.9C, a value of –187 equals –18.7C. The maximum possible temperature range is –3276.8C to +3276.7C. A discrete value is generally indicated by a single bit of an 8-bit byte. The bit number/position typically corresponds to the discrete channel number. Unless otherwise defined for outputs, a 1 bit means the corresponding output is closed or ON, a 0 bit means the output is open or OFF. With active-high inputs, a value of 1 specifies the input is in its high state (usually >> 0V), while 0 specifies the input is in its low state (near 0V). With active-low inputs, a value of 1 means the input is ON (Active low near 0V), while 0 specifies the input is OFF or in its high state (usually >> 0V). Data Types I/O values of Acromag 9xxPB modules are represented by the simple data types shown at left for temperature, percentage, and discrete on/off. Note that when transferring words, data bytes are transmitted using “Big Endian” format (MSB first, LSB second). _______________________________________________________________________________________ Acromag, Inc.
