Configuring Read-Only Raw/ASCII Devices
This chapter contains these subsections:
• Prerequisites (below)
• Read-Only Raw/ASCII Serial Devices (below)
• Read-Only Raw/ASCII Ethernet Devices on Page 26
Prerequisites
Before you can configure the ports, 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 a 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.
Read-Only Raw/ASCII Serial Devices
Read-only raw/ASCII serial
devices use the Serial
Device Configuration page
to:
• Allow connections
between a serial device,
such as a barcode
scanner or RFID
reader, to PLC(s) and/
or application(s).
• Provide an optional
filtering mechanism for
string, RFID, and
barcode data.
The PLC and application
can both communicate to
the serial device, but they
cannot communicate
directly to each other.
