Modbus TCP
Figure 2-12 - Add Modbus Master/Slave
The Ethernet is now configured in the Project Settings. It is ready to be used in the ladder diagram program as Modbus TCP or for
VersaCloud M2M Connectivity.
To configure Modbus TCP (Master or Slave) for use over Ethernet or Wi-Fi, see the
Modbus TCP Section
of this manual.
To configure VersaCloud M2M Connectivity over Wi-Fi, see the
VersaCloud M2M Connectivity Section
of this manual.
VersaGateway models can only support Ethernet or Wi-Fi individually. As the PLC on a Chip utilizes the Wi-Fi as Ethernet,
VersaGateways can only support one of either Ethernet or Wi-Fi at a time.
Modbus TCP (over Ethernet) is now ready to be used on the VersaGatway. Several additional function blocks are used with
the Modbus TCP Ethernet port in the ladder diagram project. More on Modbus and the required function blocks is
detailed in the P-Series EZ LADDER User’s Manual.
For details on configuring and using Modbus TCP (Master or Slave), refer to the P-Series EZ LADDER Toolkit Manual. It
contains in-depth information regarding using variables and Modbus.
