Modbus TCP-Offset (Gen1)
Note: This driver will be deprecated in a future release. We recommend using the Gen 2 Modbus TCP.
Review the following information for setting up and configuring the Modbus TCP-Offset (Gen1) driver.
Compatibility parameter | Compatible items |
|---|---|
Driver type | Ethernet |
When to use | TCP connection to a Modbus device |
Replaced with Gen 2 driver | Modbus TCP |
To set up and configure this device in Litmus Edge, you will need to do the following:
- Step 1: Set up and Configure the PLC Device
- Step 2: Set up the PLC Device in Litmus Edge DeviceHub
- Step 3: Configure the List of Registers
If the device is configured for Ethernet access, find its network parameters. Otherwise, use PLC software on your computer to configure the device for Ethernet access.
