Modbus is available as a serial protocol - Modbus RTU or Modbus ASCII, and as a
network protocol - Modbus TCP. CSWorks supports Modbus TCP that
allows CSWorks-powered applications to exchange data with Modbus TCP devices directly.
If you want your CSWorks application to communicate to a Modbus RTU/ASCII device,
you can use a Modbus RTU-TCP gateway appliance.
Modbus RTU-TCP gateway connects serial Modbus RTU/ASCII products to Ethernet LAN’s.
The gateway acts a pure transparent connection between serial Modbus products and
the Modbus TCP HMI/SCADA systems. A typical gateway can support multiple (up to
255) Modbus RTU/ASCII devices on the serial end. There is a well-established market
for this kind of devices and a lot of models to choose from.
CSWorks installation package includes a sample that demonstrates how a
CSWorks-based solution can be integrated with a room thermostat that supports serial
