7.5.5.- MODBUS COMMUNICATIONS
The following functions are implemented for these variables:
Function 0x04: reading registers.
Function 0x10: Writing multiple registers.
7.5.5.1.- Conguration of DHCP activation/deactivation
Table 127:Modbus memory map: Modbus TCP (Bridge) 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
7.5.5.2.- Conguration of the TCP parameters
Table 128:Modbus memory map: Modbus TCP (Bridge) 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.
7.5.5.3.- Conguration of the RS-485 gateway parameters
Table 129:Modbus memory map: Modbus TCP (Bridge) communications module (Table 3)
Conguration of the Modbus TCP parameters
Configuration variable Address Valid data margin Default value
Baud rate F500
0: 1200 - 1: 2400 - 2: 4800 -
3: 9600 - 4: 19200 - 5: 38400 -
6: 57600 - 7: 76800 - 8: 115200
4
Parity F501
0 : No parity
1: Odd parity
2: Even parity
0
Length F502 1: 8-bit 1
Stop Bits F503
0: 1 stop bit
1: 2 stop bits
0
Note: The 4 registers must be written at once (as a group), otherwise it will respond with an
error.
7.5.5.4.- MAC address of the Modbus TCP module
