This section tells you how to set up the station addresses and protocol parameters for MODBUS RTU.
MODBUS RTU station addresses and protocol parameters
To be able to use the gateway SWIRE-GW-MB within a
MODBUS RTU network, its station address, parity and baud rate must be set before use. These settings are made using
DIP switches 2 to 10 on the device’s underside.
DIP switch 1 is not assigned with a function.
The MODBUS RTU station address for the SWIRE-GW-MB is set in binary format with DIP switches 6 to 10, providing a total of 32 addresses from 0 to 31. Valid addresses for the
SWIRE-GW-MB are 1 to 31.
The baud rate of the MODBUS RTU network is set with DIP switches 2 and 3.
Possible baud rates, in kbits/s, are 9.6, 19.2, 38.4 and 57.6.
The corresponding DIP switch settings are are shown below.

07/09 MN03407002Z-EN
Terminating resistors
Terminating resistors If the RS485 communication standard is used, the first and last station in a MODBUS RTU field bus segment must terminate the field bus with an energized termination resistor. The bus termination resistor is connected externally, either as a separate terminating resistor or through a special
D-sub connector with built-in bus termination. Connect the terminating resistor, which should have a resistance of
150 (0.5 W) between the two signal lines RxD/TX (A-line) and Rx/Tx+ (B-line).
EMC-conformant wiring of the network
Electromagnetic interference can cause faults in the field bus. Their influence can be limited by implementing suitable
EMC measures, such as:
• EMC-conformant system configuration
• EMC compliant cable installation and
• Avoiding high potential differences
• correct installation of the MODBUS systems (cables, bus plug connection, etc.)
The electromagnetic interference can be significantly reduced by the use of a cable screen (shield). The following illustrations indicate the correct method for connecting the shield.

Max. cable lengths
The following electrical isolation measures apply for the
SWIRE-GW-MB interfaces:
• Potential isolation of the MODBUS-RTU to the supply voltage and to the SmartWire system
• No isolation between the supply voltage for the gateway and the supply voltage for the contactor coils
• No electrical isolation between the supply voltages and the SmartWire system.

For each communication standard (RS232 and RS485) maximum bus cable lengths are specified.
RS485
When RS485 is used, the maximum cable length depends on the cross-section of the data cable. At a conductor crosssection of 0.25 mm² (AWG24) or greater, the maximum cable length is 1000 m. With data cables of category 5, the bus length can be up to 600 m.
RS232
For the RS232 standard and a cable capacitance of u to

Initial starting
3 Commissioning
This section tells you how to take the gateway into operation.
X
Before switching on the supply voltage for the gateway ensure that the contactor coils, the bus connection and the
SmartWire system are correctly connected.
X Make sure that the gateway’s MODBUS RTU address, the parity and the baud rate for the MODBUS RTU network are set correctly with the DIP switches on the gateway’s underside.
X
Switch on the supply voltages for the contactors and the gateway.
Die gateway’s LEDs now indicate the following states:
• The ready LED of the SWIRE-GW-MB flashes.
• The U-Aux LED of the SWIRE-GW-MB is permaneltly ON.
• The MODBUS-RTU-LED is OFF (no communication via
MODBUS-RTU).
• The SmartWire LED flashes as the SmartWire slaves have not yet been configured.
• The first SmartWire module flashes the ready LED.
• The ready LEDs on all other SmartWire modules flash in pulses.
X Press the configuration button on the gateway and keep it pressed for about 2 s until the ready LED switches from flow flashing to fast flashing.
The actual configuration of the SmartWire system, i.e. all connected SmartWire modules, are now automatically read into the gateway. An address is assigned in turn to each
SmartWire station, starting with address 1 and incrementing in steps of 1. When the configuration has been read in to the
SmartWire system, the SWIRE status LED on the MODBUS
RTU gateway and the Ready LEDs on the SmartWire module change from slow flashing to continually lit. The SmartWire

Data mapping of SmartWire stations
Abbreviated and full bit representation
Depending on the register data area, the status data (input data of the SmartWire stations) and control data (output data of the SmartWire stations) are output either in an abbreviated form or in full.
Abbreviated views show only the first status/control bits of each SmartWire station. For SmartWire stations with a higher number of status/control bits than shown in the abbreviated representation, only the allowed number of bits is shown. In the full view, all of the data of the SmartWire station is shown. Depending on the SmartWire station, this view may contain unused bit fields that are also transferred through MODBUS RTU.
The example below illustrates the abbreviated representation of status and control data for the stations
SWIRE-DIL and SWIRE-4DI-2DO-R.

The display format for status and control data depends on the selected register area.
For the status data you can select two different abbreviated representations:
• Abbreviated status data 1: Two bits per SmartWire station, register area 40007 to 40008
• Abbreviated status data 2: Four bits per SmartWire station, register area 40010 to 40013
Abbreviated control data can be shown only in one representation (register area 40001 to 40002) and contain two bits per SmartWire station. The table below lists the status and control data shown in each abbreviated representation.

Input I4 Input I3 Input I2 Input I1 h Whether it is best to select an abbreviated or a full data representation depends on the type of SmartWire station:
An abbreviated representation is best suited for stations with a small number of status or control bits, as this reduces the number of unused bit fields within the
MODBUS RTU protocol; a full representation is best used for stations with a large number of status or control bits.

Control data areas
The control (output) data of the SmartWire stations are located in two different register areas, one for the abbreviated representation (two control bits per SmartWire station, register area 40001 to 40002) and one for the full representation (four control bits per SmartWire station, register area 40003 to 40006). The MODBUS RTU gateway does not support the simultaneous use of both of these data areas, since this could cause inconsistencies between the control data in the two register areas. To switch between the two control data areas, you must switch the MODBUS RTU gateway off and on again.

Check bits
The register area for parity bits is used to determine whether a station on the SmartWire has failed or has an internal fault state. Each SmartWire station has a parity bit. Within the register area, the parity bits are arranged according to the physical arrangement of the SmartWire stations. The parity bits are defined as follows:
Table 20: Definition of parity bits
Parity bit SmartWire station status
Station connected and working correctly
Station has failed or is defective
Each parity bit represents a logic OR link of the status and life bit of its SmartWire station. It therefore contains the key diagnostic information about its SmartWire station, so that an additional evaluation of status and life bits may not be necessary.

Register area 40078 is used for evaluating connected or failed SmartWire stations. It contains a life bit for each station for this purpose. Within the register area, the life bits are arranged according to the physical arrangement of the
SmartWire stations. The life bits are defined as follows:

Status bits
Each SmartWire station sends status bits to the MODBUS
RTU gateway. The status bit indicates whether the station is working correctly or has changed to a fault state. Status bits are contained only in the full representation (register area
40014 to 40077). Within this register area the status bit is the highest bit of the lowest status data byte of its station.

Any failed SmartWire stations remain in this representation and are removed only at the next startup of the SWIRE-GW-MB.
Setting the watchdog timer
The MODBUS RTU gateway has a built-in watchdog timer, which monitors the data traffic within the MODBUS RTU network. The watchdog timer monitors the interval between two control data write operations. If the interval exceeds the set value, the watchdog triggers an internal error state in the
SWIRE-GW-MB, which causes all control data of the
SmartWire station to be deleted (logic 0). The control data status (logic 0) remains active until it is set by new write signal.
The timeout value of the watchdog timers can be set with the two register areas 44097 and 44098. Valid time values are written to the least significant byte of the respective register. The watchdog timer has a polling interval of 10 ms.
Timeout values of 10 to 2550 ms can be set.
The set time interval is temporarily written to register area
44097. In the event of a power failure (U
Gateway
) this data is deleted. Any data written to the non-retentive memory area
(register area 44097) of the SWIRE-GW-MB are also copied to register area 44098, where they are available as read information.
Within register area 44098 the set time interval is retentively stored to remain available after a power failure. The default timeout value is 100 ms.

The data of the SmartWire stations are mapped to the holding register of the SWIRE-GW-MB. Normally, the holding register area can be both read and written to. Some data areas (such as the SmartWire stations’ status data) are read-only. For any write operations to read-only areas the
MODBUS RTU gateway returns an error code.

For function codes that are not supported,the response message from the MODBUS slave contains the function code of the request message increased by 128 (0x80).

Diagnostic data
Diagnostics of the SmartWire stations can be performed in a number of ways:
• As long as the SmartWire modules communicate with the gateway they send a status bit, which is included in the full
status data. (section "Status bits", page 39)
• The SWIRE-GW-MB monitors the SmartWire stations. It recognizes the failure of any stations and sets the corresponding life bit.
• Failed or faulty SmartWire modules are also included in the parity bits’ register area.

Operation through
MODBUS RTU
07/09 MN03407002Z-EN
Checking the SmartWire configuration
The SmartWire connection system initializes when the configuration key on the MODBUS RTU gateway is pressed.
During this process, addresses are automatically assigned to all stations and their device files are read in to the MODBUS
RTU gateway. A correct system initialization can be verified through register areas 40079 to 40142 (manufacturer and device ID) and register 40143 (number of SmartWire stations). Within the manufacturer and device ID register area all stations are listed with the device data that the gateway read during initialization. The number of SmartWire stations that the gateway recognized during its initialization is contained in register 40143. Incorrectly initialized
SmartWire stations are not included in the register areas for manufacturer and device ID and for the number of
SmartWire stations.
Before operation, read out both register areas and compare them with the physical layout of the SmartWire rung. This will help you identify any faulty modules of communication connections before starting operation.
