Cable Accessories for Modbus Port 1
Overview
This section describes the cable and D-shell adapters needed to connect Modbus
Port 1 to a programming station. It also provides pinouts for the adapters.
Cables
The cable connecting a programming station to the CPU (via Modbus Port 1) can
be up to 9.5m long. Three premade cable assemblies are available from Schneider
Automation:
All three assemblies are standard eight-position, foil-shielded, flat telephone cables
with male RJ45 connectors on each end. One RJ45 connector plugs into Modbus
Port 1 on the CPU, and the other plugs into a female D-shell adapter that fits onto
the programming station.
D-Shell Adapters
Two D-shell adapters are available from Schneider Automation for CPU-to-
computer connections:
A 110 XCA 203 00 9-pin adapter for PC-AT type stations
A 110 XCA 204 00 25-pin adapter for PC-XT type stations
These adapters have an RJ45 jack on one end that allows them to clip directly onto
a cable assembly.
