1-1 Overview
This section provides an overview of connecting an NS-V1/V2 PT to an OMRON
Programmable Controller that supports Host Link communications.
The NS-V1/V2 PT is connected 1:1 to the CPU Unit or a Host Link Unit of an OMRON PLC.
Host Link communications are used to read and display or write the words and settings in the
host PLC.
NS-V1/V2 PT serial ports A and B can both be connected to a host by means of the Host
Link protocol.
Reference
When an NS-V1/V2 PT and a PLC are connected by
Host Link, it is not possible to change to RUN Mode.
If the PLC is set for RUN Mode, it is automatically
switched to Monitor Mode. For example, if a
compatible Programming Console is connected to
the PLC and the PLC operating mode is switched to
RUN mode, the password display for the Monitor
Mode will be displayed at the Programming Console.
