Question
Is it possible to connect multiple PLCs to
a single Programmable Terminal?
Answer
Multiple PLCs cannot be cannot be connected directly to an NT-series PT.
The 1:N NT Link mode allows a single PLC to connect to multiple PTs (PLC:PT
= 1:N, where N ≥ 1). It does not support PT:PLC = 1:N connections. Only
one PLC can be connected to a PT.
On the other hand, data can be collected from other PLCs through a data
link in a network such as Controller Link. The collected information can
be transferred to the PT, so data from multiple PLCs can be collected in a
single PT indirectly.

When multiple PTs are connected to a PLC with 1:N NT Link communications and an error occurred in one of the PTs, is it possible to detect that error from the PLC?
