Accessing C445 System Parameters with the Logic Engine

C445 System Parameters are accessible in the Logic Engine
in the Variables window. Open the Variables List, then
System Parameters.
There are 2 categories under System Parameters.
1. System In
2. System Out
System In parameters are parameters that can be monitored
from the C445 Motor Management Relay and the System
Out parameters are parameters that can be used to control
the C445. There are multiple categories under both the
System In and System Out categories, to make finding
specific parameters easier.

Description
Input to be type converted
Type converted IN
For example, to monitor the running status of the motor being
controlled by the C445, the "MotorControlStatus.Running1" bit
can be found under the System In / Control Monitor Control
Source Status / Motor Control Status category. If the Logic
Engine is the Remote Control source and the active control
source for the C445 is the Remote control source, the Logic
Engine can access the "LogicMotorControlWord.Run1" bit
under the System Out / Logic Motor Control category and
use it to run the motor.
For additional information concerning the system
parameters, refer to the Modbus Register map in
Appendix D.
