XYR5000 Wireless Instrumentation Tech Note: Experion PKS® Modbus RTU Integration Issued: October, 2004 MODBUS Integration Overview The Wireless Transmitter integration to Honeywell TPS (PM, HPM, xPM) or Experion PKS is by Modbus RTU into a Serial Interface Module (SIM). Each wireless transmitter will require 10 "Little Endian Byte Swapped" 32 Bit floating-point format registers to provide both transmitter PVs' and Alarm functions to the host system. Each XYR5000 Base Radio will require 10 16-bit numeric. There are 2 methods of assigning Modbus addresses to each base station and associated transmitter(s): "Device Mode" or "Register Mode". The default "Device Mode", assigns a separate Modbus node number to each wireless transmitter. This mode is easy to use (except that the Modbus node address equals the transmitter ID 1 plus 1), but is very limiting because the SIM only accommodates 16 slave devices, or in other words 16 transmitters when using this mode. We therefore recommend using "REGMODE" (under RS-485 -> MODMAP) for all integrations. In this mode a single Modbus 03 command can be used to communicate to all the transmitters connected to one base radio. As a result a maximum of 16 base radios, with multiple transmitters each, can be interfaced to a single SIM-FTA. Please note that in REGMODE, each transmitter is given a block of 10 registers in the base unit's contiguous memory space for accessing its data (e.g. status values, primary & secondary PVs', etc). The maximum number of wireless transmitters that can be integrated to the Experion PKS is determined by the speed of controller module and the mix of inputs. The c200 controller operating at 50 msec can support three (3) SIM modules. The C200 controller operating at 5 msec can support only one (1) SIM. Each SIM module can support two SIM-FTA’s. Each SIM-FTA can support a maximum of 48 wireless transmitters with five (5) floating point each. One array is needed to read in the Base Radio status (integer) Therefore, the theoretical maximum number of congruent wireless transmitters that can be supported by Experion PKS operating at 50 msec: 3 SIM’s x 2 SIM-FTA x 16 array slots x 3 transmitters = 288 transmitters per C200 controller Note: The Wireless solution is intended for monitoring and/or SCADA applications.

Overall Modbus Interface Connections (Refer to

Figure 1 shows the typical component connections associated with a Modbus Field Termination Assembly (FTA) installation for reference.

Figure 1 Modbus Serial Interface connections

Mounting Modbus FTA

The Modbus FTA can be mounted on a standard FTA Mounting Channel, DIN rail (35 x 7.5 mm top hat rail), or surface mounted on a wall. The FTA is designed for mounting in a cabinet or in a controlled environment. Do not expose the FTA to the weather. The FTA has a mounting hole in each corner. To mount on a DIN rail, you must attach the DIN rail adapter to the bottom of the FTA, using the hardware supplied. Otherwise, mount the FTA on Mounting Channel standoffs or drill holes and use screws and non-metallic spacers to attach the FTA to a wall. Be sure the FTA is grounded either directly or through the mounting means.

Wiring Modbus FTA to Power Adapter

Use the procedure in the following table to wire the Modbus FTA to the Power Adapter.

Step Action 1 Is the Modbus FTA mounted in a cabinet with the Power

Adapter? Yes, be sure you have the appropriate number and length of Honeywell internal cable MU-KLAMxx on hand. Go to the next Step.

No, be sure you have the appropriate number and length of Honeywell external cable MU-KSXxxx on hand. Go to the next Step.

(Note: Cable must have 2 individually shielded, twisted pairs)

2 On one twisted pair mark one lead P- and the other P+ at both ends of the cable. On the other twisted pair mark one lead S- and the other S+ at both ends of the cable. Repeat this for other cables, as applicable.

3 Locate the J2 (CHANNEL A), 6-pin connector on the Power Adapter. Observing polarity, connect the cable lead marked P- to pin 1 - PWR CUR and lead marked P+ to pin 2 + PWR CUR. Connect the shield wire for this pair to pin 3 SHD. Observing polarity, connect the cable lead marked S- to pin 4 - SER and lead marked S+ to pin 5 + SER. Connect the shield wire for this pair to pin 6 SHD. See the connection diagram in Figure 2 for reference. (Note that the shield wires are connected to ground at the Power Adapter end only.)

4 Locate the J1, 4-pin connector on the FTA "A". Observing polarity, connect the cable lead marked P- to pin 1 - PWR CUR and lead marked P+ to pin 2 + PWR CUR. Trim the shield wire for this pair close to the cable insulation. Observing polarity, connect the cable lead marked S- to pin 3 - SER and lead marked S+ to pin 4 + SER. Trim the shield wire for this pair close to the cable insulation. See the connection diagram in Figure 2 for reference.

5 Do you have a second FTA to be connected to the Power Adapter?

Yes, continue with Step 6.

No, exit this procedure and go to the next section Wiring Modbus FTA to Modbus devices.

6 Locate the J3 (CHANNEL B), 6-pin connector on the Power Adapter. Observing polarity, connect the cable lead marked P- to pin 1 - PWR CUR and lead marked P+ to pin 2 + PWR CUR. Connect the shield wire for this pair to pin 3 SHD. Observing polarity, connect the cable lead marked S- to pin 4 - SER and lead marked S+ to pin 5 + SER. Connect the shield wire for this pair to pin 6 SHD. See the connection diagram in Figure 2 for reference. (Note: Shield wires should be connected to ground at the Power Adapter end only)

7 Locate the J1, 4-pin connector on the FTA "B". Observing polarity, connect the cable lead marked P- to pin 1 - PWR CUR and lead marked P+ to pin 2 + PWR CUR. Trim the shield wire for this pair close to the cable insulation. Observing polarity, connect the cable lead marked S- to pin 3 - SER and lead marked S+ to pin 4 + SER. Trim the shield wire for this pair close to the cable insulation. See the connection diagram in Figure 2 for reference.

Wiring Modbus FTA to Modbus Devices

Making EIA-232 (RS-232) connections You will need a null modem cable with a 25-pin, male connector to connect the EIA-232 Modbus device to the J2, DB-25 type connector on the FTA. Use the J2 connector pinout data in Figure 3 to construct the EIA-232 interface cable. Since individual Modbus device connections may vary, be sure to modify the common EIA-232 pin outs shown in Figure 3, so that the FTA Transmit Data pin (2) connects to the Modbus device Receive Data pin and the FTA Receive Data pin (3) connects to the Modbus device Transmit Data pin. Be sure the length of the EIA-232 interface cable does not exceed 15 meters (50 ft).

Figure 3 Pins common to RS-232 25-pin connector and FTA J2, DB-25 type connector.

Making EIA-422/485 connections You will need appropriate cable, such as Belden Corporation Type 9271 Industrial Twinax, to connect up to 15 EIA-422/485 Modbus devices in multidrop fashion to the J3, 5-pin connector on the FTA. Use the connection details shown in Figure 5 and the following guidelines to configure a multidrop EIA-422/485 interface. The recommended maximum length for the interface cable is 300 meters (1000 ft). However, this can be extended up to 1220 meters (4000 ft) with the appropriate cable (Belden type 9182). Please consult with Honeywell Technical Assistance for the recommended cable. To avoid potential ground loops, connect the shield for the interface cable to ground at the FTA end only. See Figure 4 for wiring details. To minimize signal reflections, connect a 120 Ω, ±10%, ½ Watt resistor across J3 pins 1 and 5 and across the Data (+) and Data (-) terminals on the last device in the link. (Note: the resistor value may be different based on the requirements of the actual cable used.) The FTA includes two (2) ¼ Ampere fuses (F1 and F2) to protect it from excessive current draw on the data lines.

Configuring Wireless Transmitter Inputs on Experion PKS or Plantscape 1. Select the block SINUMARRCH (SI Numeric Array) and drag it into a new Control Module.

Fig. 5 SINNUMRRCH Selection


Open the SINUMARRCHA module and rename it.

Fig. 6 SINNUMRRCH Block 2. Select the correct SI module and assign the channel to an available slot. Ex. 0-15 for FTA01 & 16-

31 for FTA02.

Fig 7 Configuring SINNUMRRCH 3. Fill in the serial link device address.

• This would be the base station address.

4. Enter the Starting Element Index. • This would be the first valid transmitter memory location.

5. Enter the Number of Numeric Values.

• This would be last transmitter memory location.

6. Leave Write option = WRITEONDIFF • (This option does not apply to Experion PKS)


Fig 8 Configuring SINNUMRRCH 7. Fill in the AUXDATA[0] through AUXDATA[3] as per the table below. Examples are: AUXDATA[0] NaN Leave as NaN AUXDATA[1] NaN Default value of 1.5 seconds for retries AUXDATA[2] 232.0 RS232 no modem control AUXDATA[3] 9600.0 9,600 Baud Rate with no parity bit

AUXDATA[0] Specifies the Keep Alive Address for a Modbus coil.

Note: not applicable to the XYR-5000

This parameter tells the Modbus system that the Experion PKS subsystem is functioning. It can be configured separately on each array channel block, but no two-array channel blocks should write to the same coil. The coil address must be within the range 00001 to 09999. Note: When this parameter is NaN, the Keep Alive function is inactive. If you want to check the Keep Alive coil, you must program the Modbus device to do so.

AUXDATA[1] Specifies the time interval in seconds to wait before attempting a message retry.

If a valid response is not received after three tries (original plus two retires), a MSGTMOUT error results. The range is 0.25 to 5 seconds on NaN. If NaN is specified, the default timeout is 1.5 seconds. A timeout value can be configured separately for each array channel block.



AUXDATA[2] Specifies the signaling protocol and modem control in an integer/decimal format: mmm.n Where mmm is the signaling protocol and n is the modem control (0 = OFF and 1 = ON). For example, 232.1 indicates EIA-232 with modem control ON. The other choices are 232.0 and 485.0. EIA-232 permits use of an external modem.

The first valid array channel block loaded to the Controller with values in AUXDATA[2] and AUXDATA[3] sets the mode and baud rate for the FTA communications. This means that AUXDATA[2] AUXDATA[3] must contain the same value for all array blocks configured through the same FTA. If array blocks loaded later to that FTA have different AUXDATA[2]/[3] values, an AUXMATCH error results. The modem control feature switches the following signals: RTS, CTS, DSR, DTR, and DCD. When AUXDATA[2] is NaN, the protocol is EIA-232 and modem control is OFF.

AUXDATA[3] Specifies the baud rate in an integer/decimal format: bbbbb.n Where bbbbb is the Baud Rate and n is the Parity (0 = None, 1 = Odd, 2 = Even).

The legal baud rates are 19200, 9600, 4800, 2400, and 1200. NaN (dashes) results in a default value of 19200 baud with odd parity.

AUXDATA[4] to AUXDATA[7]

These parameters are not applicable to a Generic Modbus interface.

Set these parameters to NaN when communicating with a Modbus.

STARTINDEX and number of elements parameters configuration:

The value configured for the STARTINDEX parameter in a given Array Channel block determines the Modbus Start Index and function. Only one type of external data can be accessed per Array Channel block. The number of elements parameter (NNUMERIC) Numeric Array block determines the number of numerics’ in a given data array. The following table shows the relationship between Modbus functions and the STARTINDEX and number of elements parameters. The Start Index Ranges defines the Modbus address map. The most significant digit in this column identifies the Modbus function (for example,). The lower four digits define the starting address to access data for the given Modbus function. The address ranges 2xxxx, 8xxxx instruct the SI firmware of the type of data to expect.

The maximum number of elements specifies the maximum number of numerics that can be configured for a given Start Index Range and block type. All of the specified elements are read in a single transaction.

They are to be configured in an array, NNSTIX = 20071 and the NNUMERIC = 15. The Base Radio registers are 16-bit un-signed integers and can be used to monitor the status of the base radio and the communication status of all transmitters. The NNSTIX for the Base Radio is 90001 and the NNUMERIC is 10.

The figure below is an example of an array channel function block for a group of three (3) wireless transmitters. Add the appropriate amount of pins to the numeric array to match your configured NNUMERIC.

Transmitter Status Registers: The statuses of the XYR5000 wireless transmitters must be “unpacked” from the individual 32-Bit IEEE Floating Point holding registers. To decode the transmitter statuses, take the value of the register and subtract the largest value listed in Table III that does not cause the result to be negative (-). Take the resulting total from the subtraction and subtract the next largest number possible and so on until the net result is zero (0). Each value used in the subtraction indicates the status or statuses of the XYR5000 Wireless transmitters. This can be done using the AUXCALC block in control builder.


The Base Radio holding registers are 16-bit un-signed integers and can be used to monitor the status of the base radio and the communication status of all transmitters. The Base Radio Device Type is 255. Table IV Base Radio Holding Registers
