1.20.- TCP2RS MODBUSTCP CONVERTER
The TCP2RS converter connects equipment which works with serial communication (RS-232 /
RS-485) to an Ethernet network using the IP protocol (ModbusTCP for connection–oriented
communications).
When adding or modifying this device, see ‘Editor Manual’, the following dialogue appears
Where
• Name: Alphanumeric field that uniquely identifies the device throughout the program. There
are no two devices in the configuration with the same name.
• Description: Alphanumeric type data to enter a brief description of the device.
• Address converter: Corresponds to the address the program uses to communicate with the
device. This parameter can be an IP address or a name.This address should not be confused
with the MAC address.
• Port: Corresponds to the communications port:By default the Modbus TCP protocol will
communicate through port 502.
• Configuration port: Corresponds to the communication port the program uses to configure
the device. This is port 30718 by default.
Unlike TCP2RS devices, the program does not configure any Modbus TCP device
parameters automatically, using the configuration port only to detect and verify that the
device configuration is correct. To configure or assign an IP address to Modbus TCP
devices, consult the device manual.
For a TCP2RS device to be able to communicate through a router, perform the following
steps:
1 – In the ‘Address converter‘ field enter the router's IP address.
2 – In the ‘Port” field enter the communications port and redirect this port on the router to the
device's communications port.
3 – Redirect the configuration port on the router to port 30718 of the converter.
N.B.: For information on re-addressing ports consult the router user manual.
