Circutor CVM-A1000 - Page 313

● When programming the transmission speed, Baud rate:
, ... Possible transmission speeds: 9600, 19200, 38400, 57600, 76800 or
115200�
● When programming the parity:
Even parity, Odd parity, No parity.
● When programming the number of stop bits:
, Possible numbers of stop bits: 1 or 2�
If no button is pressed for 5 minutes, the display screen changes automatically to the default
screen, which displays the voltage measurement of 4 parameters.
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 147: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 148: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.
