8.6 Configuring devices at Modbus TCP
8.6.1 Implemented Modbus functions
The devices support the following functions for accessing process data, parameters, dia-
gnostics and other services.
Function Code
1 Read Coils – reading multiple output bits
2 Read Discrete Inputs – reading multiple input bits
3 Read Holding Registers – reading multiple output registers
4 Read Input Registers – reading multiple input registers
5 Write Single Coil – writing single output bit
6 Write Single Register – writing single output register
15 Write Multiple Coils – writing multiple output bits
16 Write Multiple Registers – writing multiple output
23 Read/Write Multiple Registers – reading and writing multiple registers
8.6.2 Modbus registers
Address Access Meaning
0x0000…0x01FF read only Process data of inputs (identical to registers 0x8000…
0x8FFF)
0x0800…0x09FF read/write Process data of the outputs (identical to registers
0x9000…0x9FFF)
0x1000…0x100B read only Module identifier
0x100C read only Module status
0x1017 read only Register mapping revision (always 2, if not, mapping is
incompatible with this description)
0x1020 read only Watchdog, actual time in ms
0x1120 read/write Watchdog, predefined time in ms (default: 500 ms)
0x1130 read/write Modbus connection mode register
0x1131 read/write Modbus Connection Timeout in sec. (def.: 0 = never)
0x113C…0x113D read/write Modbus Parameter Restore (reset of parameters to de-
fault values)
0x113E…0x113F read/write Modbus Parameter Save (permanent storing of para-
meters)
0x1140 read/write Deactivate protocol
Deactivates explicitly the selected Ethernet protocol:
n Bit 0 = deactivate EtherNet/IP
n Bit 1 = deactivate Modbus TCP
n Bit 2 = deactivate PROFINET
n Bit 15 = deactivate web server
0x1141 read/write Active protocol
n Bit 0 = EtherNet/IP active
n Bit 1 = Modbus TCP active
n Bit 2 = PROFINET active
n Bit 15 = Web server active
0x2400 read only V1 in mV: 0 at < 18 V
