• View OCS (RCS) Status
This screen contains both a single enumerated editable field that sets the MiniOCS / MiniRCS scan mode
and status fields that display information about the internal state of the MiniOCS/ MiniRCS. Pressing the
↑ and ↓ keys scrolls through the different items. Pressing Esc returns to the System Menu.
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. Process data for operator interface
OCS Net Use Shows the percentage of the network used by the Mini.
All Net Use Shows the percentage of the network used by all devices on the network.
Ladder Size Shows the number of bytes used by the ladder program.
Config Size Shows the number of bytes used by the I/O configuration
Text Size Shows the number of bytes used by the text screens
Firmware Rev Shows the execution engine firmware version.
BIOS Rev Shows the BIOS firmware revision.
FPGA Rev Shows the FPGA Image version.
Self-Test Shows if the power-up self-test passed or failed by displaying Ok or Fault.
