Parameter

Description


OCS Mode

Displays the current scanning mode (Idle, Run, DoIO). In Idle mode, the I/O is
not scanned and the OCS ladder program does not execute. The green “RUN”
LED is OFF. In Run mode, the ladder program executes and the green “RUN”
LED illuminates. DoIO mode is similar to Run mode, except the ladder logic is
not solved. When the OCS is in DoIO mode, the user is able to exercise all of
the I/O from Cscape, without interference from the ladder program. In this mode
the green “RUN” LED flashes. This feature is a valuable troubleshooting tool.


Scan-Rate

Shows the number of milliseconds for the scan. The scan-rate is the sum of the
time required to execute the following items:

a. Scan inputs
b. Solve logic
c. Write outputs
d. Handle network communications
e. Handle host communications request
f.
