Modbus TCP Interface
The Modbus TCP interface will support Modbus data
sources such as PLCs, MCCs, analyzers and similar devices
communicating Modbus TCP. The Modbus TCP interface is a
Modbus Client reading and writing data from/to Modbus Server
devices. The Modbus server devices can be Modbus TCP devices
or Modbus serial devices using a Modbus TCP gateway.
The Modbus TCP interface supports the following types of
data access:
Reading input data from Modbus Coils, Discrete Input,
Holding Registers, and Input Registers.
Writing output data to Coils and Holding registers.
All reads will be performed periodically and outputs will be
sent when they are written.
