Configuring Modbus/RTU and Modbus/ASCII Slaves
and Masters
For pure Modbus devices, the DeviceMaster UP supports:
• Modbus/RTU serial slaves
• Modbus ASCII serial slaves
• Modbus/RTU serial masters
• Modbus/ASCII serial masters
• Modbus/TCP masters
Note: All masters can communicate to all slaves.
Prerequisites
Before you can configure the serial ports for this mode, make sure that you have done the following:
• Installed the hardware
• Installed PortVision DX
• Configured the DeviceMaster UP IP address using PortVision DX
• If necessary, uploaded the latest Modbus/TCP firmware using PortVision DX
Note: The DeviceMaster UP provides an Modbus/TCP interface, which may or may not have the Modbus/
TCP firmware loaded (depending on the model you purchased). Models that have Modbus/TCP loaded
on the DeviceMaster UP are identified in PortVision DX and the DeviceMaster UP is labeled
accordingly.
If you need to perform any of these procedures or locate the latest files, see Overview on Page 5.
