7�9�5�- MODBUS COMMUNICATIONS
The following functions are implemented for these variables:
Function 0x04 : reading registers.
Function 0x10 : Writing multiple registers.
7.9.5.1.- Configuration of DHCP activation/deactivation
Table 175:Modbus memory map: Modbus TCP (Switch) communications module (Table 1)
Configuration of DHCP activation/deactivation
Configuration variable Address Valid data margin Default value
DHCP Flag F23A
0 : Deactivation
1 : Activation
1
7.9.5.2.- Configuration of the TCP parameters
Table 176:Modbus memory map: Modbus TCP (Switch) communications module (Table 2)
Configuration of the Modbus TCP parameters
Configuration variable Address Valid data margin Default value
IP Address F230 - F231 1 long : 4 characters -
Subnet Mask F232 - F233 1 long : 4 characters -
Gateway F234 - F235 1 long : 4 characters -
Note:
The module resets to activate the configuration.
Note: The 6 registers must be written at once (as a group), otherwise it will respond with an
error.
