Main Menu, returns to the main menu, Figure 25.
7.10.5.- MODBUS COMMUNICATIONS
The following functions are implemented for these variables:
Function 0x04: reading registers.
Function 0x10: Writing multiple registers.
7.10.5.1.- Conguration of DHCP activation/deactivation
Table 160:Modbus memory map: Modbus TCP (Switch) communications module (Table 1)
Conguration of DHCP activation/deactivation
Configuration variable Address Valid data margin Default value
DHCP Flag F23A
0 : Deactivation
1: Activation
1
7.10.5.2.- Conguration of the TCP parameters
Table 161:Modbus memory map: Modbus TCP (Switch) communications module (Table 2)
Conguration 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 conguration.
Note: The 6 registers must be written at once (as a group), otherwise it will respond with an
error.
7.10.5.3.- MAC address of the Modbus TCP module
The function implemented for this variable is:
Function 0x04: reading registers.
Table 162:Modbus memory map: Modbus TCP (Switch) communications module (Table 3)
MAC address of the Modbus TCP module
Configuration variable Address Valid data margin
MAC address F236 - F238 3 integers : 6 characters
309
