Figure 9.9 shows I/O link connections to a PLC interface module (cat. no.
3500-NA1) both as a middle device and as an end device on a link.
Connection is to the X4 terminal strip. Terminals 1, 2, 9, and 10 are
connected internally for line 1 (blue-insulation conductor). Terminals 3, 4,
7, and 8 are connected internally for the shield. Terminals 5 and 6 are
connected internally for line 2 (clear-insulated conductor). At each PLC
interface module, connect the shield drain wire of each cable segment to
give the shield continuity. However, never ground the shield at a PLC
interface module. At a PLC interface module connected as an end device
on a link, connect a 150-Ohm 1/4-Watt termination resistor across the
signal lines.
