1.2. Comtrol Modbus Solutions
If you ordered the Modbus part number for your DeviceMaster UP, Modbus/TCP is loaded on the
DeviceMaster UP by default. You may want to review our other Modbus solutions to make sure that the
feature rich Modbus/TCP application is what you want to use. Optionally, Modbus Router or Modbus Server
may by more effective for your particular environment.
The Comtrol web site provides information about the differences between the three Modbus solutions:
• M ODBUS /TCP
• M ODBUS S ERVER
• M ODBUS R OUTER
In addition, the DeviceMaster UP product CD and ftp site also provide these documents for your reference.
