Ethernet +: Support the standard Modbus TCP protocol, it can communicate with the configuration, touch screen, PLC and
other third-party host computers, which must support Modbus TCP protocol. Among them:
Ethernet default parameters:
IP: 192.168.1.111
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
2.4. Module parameter configuration method introduction, when the module is used as remote IO
There are three ways to configure remote IO parameters:
1
It can be configured via programming software - tools - remote modules (recommended);
2 It can be configured via the hardware configuration and TO instructions, when the module is hung behind the host PLC
through the parallel port;
3
It can be configured via MODW instructions through the serial communication.
2.5. Parameter configuration example: The module is configured by programming software remote module tool
Hardware connection
1
Through the RS485 communication port (the terminals of A +,B- on the module) connection: If the computer has a serial
port, you can use the converter of 232 to 485 connecting with the module; if it has one USB interface, you can use the
converter of USB to 485 connecting with the module.
2 Through the connection of Ethernet + communication interface: You can connect the module with the computer's
network port directly by the standard network cable, or take the computer and module connected to the switch.
