Power and Cabling Requirements
Your communication cable requirements depends on your particular application.
There are two types of configuration possibilities: point-to-point (a single operator
interface connected to a PLC) and multi-drop (multiple operator interfaces
connected to a PLC).
D
Point-to-Point --
If you only need one operator interface connected to one
PLC, then choose the appropriate cables from the chart on page 11.
D
Multi-drop --
By using an OptiMate OP--9001 Communications Master,
multiple Optimate units can be connected to a single PLC. Up to 31 individual
units can be connected in a daisy-chain fashion to the OP--9001.
Communications are via RS422 between the OP--9001 and the operator
interfaces. When using a quality shielded cable, a total distance of up to 4000
feet between the OP--9001 and the last operator interface unit in the chain
can be achieved. If the distance is 30 feet or less, a ribbon cable with
easy-to-install crimp-on ribbon connectors can be used.

1. Point-to-Point
A single cable connection
from the PLC to the panel
gives you access to the
PLC’s data registers and
ladder logic.
2. Multi-drop
Multiple OP-panels can be interfaced to a single PLC.
This requires the use of the OP-9001 Communications
Master. With the Communication Master, up to 31
panels can be interfaced to a single CPU port. Each can
be programmed for entirely different functions. Panels
can be distributed up to 4000 feet* from the OP-9001.
*NOTE:
Please read and follow the cabling requirements in the OP-9001 User
Manual (OP-9001-M) when using multiple panels. Failure to follow the guidelines of
the User Manual may affect the integrity of the RS422 link, resulting in
communication errors.
