Modbus TCP Server

Modbus TCP Server Enabled

The PXG can also function as a Modbus TCP server, providing channel data as Modbus registers from both Modbus
and INCOM devices. The device addresses and Modbus maps for these devices can be downloaded directly from
the PXG.

Normally, the PXG provides only channel data supported by its internal device definition: the EDS file. However, the
PXG also has a Modbus "pass through" mode, allowing a Modbus client to connect directly with the device and use
the device's native Modbus register set. You can set pass through for COM1, COM2, and Network 2 (Ethernet).

Modbus TCP Server Setup

Server setup is in Settings, on the Network Access tab. Choose Edit to access the configuration settings. You
enable the server under the Access Control group (Modbus TCP must be enabled to see Modbus TCP Server
Configuration). You can also change the TCP port. To enhance security, enable Trusted Hosts and then add the IP
address of each Modbus client using Add Trusted Host/IP Address. Under Modbus TCP Server Configuration, you
can set up the way the server responds to client requests. For example you can allow the server to respond to write
commands, where appropriate, or not to allow them.
