Can multiple Programmable Controllers (PLC) be connected to a single Programmable Terminal (PT)?Last Updated: September 20, 2018
With the Programmable Terminal "NT Series", multiple PLCs cannot be directly connected to a single PT.
In the NT link (1:N mode), PLC:PT=1:N (N= 1 and above), not PT:PLC=1:N.
Only single PLC can be connected to the PT.
In order to collect data of multiple PLCs into a single PLC, link their data through the Controller Link Network to gather information into a single PLC and make the PLC containing gathered information communicate with a PT.
