Connection Method

Connect an NT20-ST121-E and PLC made by OMRON with an I/O cable.
Before making the connection, check the series and model of the PLC to
which the connection is to be made. A list of the PLCs that can be connected
to an NT20 using C200H direct communications is presented below.

time, since there is some fluctuation in the PLC cycle time, the system opera-
tion may not be consistent, and this should be born in mind when designing
the system.
The NT20 PT is connected to the PLC using the NT20-IF001 and NT600M-
LB122-V1.
The connection conditions are different for C200H/HS, C200HX/HG/HE and
C@@H.
