Communicating with the PLC Using C200H Direct Communications
Section 2-7
Mounting the NT20-IF001
1.
As shown in the following diagram, connect the NT20 connector on the
back of the NT20-IF001 to the expansion interface connector on the NT20
PT.
2.
After connecting the connector, secure the NT20-IF001 with the two
screws. The tightening torque is 0.6 N
•
m.
3.
As shown in the following diagram, hold the Interface Unit with the notch
on the left and press the Interface Unit into the NT20-IF001 until it clicks
into place.
4.
Connect the ground screw on the NT20-IF001 to the NT20 using a short
wire (100 mm max.), and connect the ground through the NC terminal.
Reference:
The NC terminal on the NT20 also serves as a functional ground. Do not con-
nect this terminal when using only the NT20 (grounding is not required).
!Caution
Always turn off the power at the PLC and PT before connecting the C200H
interface cable. Otherwise the system may operate unpredictably.
!Caution
Make sure that the power supply to the PT is OFF before connecting or dis-
connecting the Interface Unit. After mounting an NT20-IF001, be sure to
tighten its two screws. Do not touch the PCB (printed circuit board) with bare
hands.
!Caution
After connecting the communications cable, always secure it with the screws.
Otherwise the cable may disconnect, causing operation to fail.
