7.6 Commissioning the Device in Modbus TCP
7.6.1 Implemented Modbus functions
The TBEN-S modules with Modbus TCP support the following functions for accessing process data,
parameters, diagnostics and other services:
7.6.2 Modbus Registers
Function codes
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 a single output bit
6 Write Single Register – writing a single output register
15 Write Multiple Coils – writing multiple output bits
16 Write Multiple Registers – writing multiple output registers
23 Read/Write Multiple Registers – reading abnd writing multiple registers
Address Access
ro = read only
rw = read/write
