Output Variable Table
The read-only status variable is located on the CCW Global Variables tab in
visual checkbox format, and in _IO_X
x
_ST_
yy
string format, where:
•
x
represents the expansion slot number 1…3 for the Micro850 controller
and slot number 1…8 for the Micro870 controller
•
yy
represents the generic number from 00 to 47.
Channel Status (CCW Var: _IO_Xx_ST_31:00)
Channel status variable is a replica of the reading from FPGA responses.
Whenever any channel control is enabled by the user during RUN mode, the
corresponding channel status variable is also checked as enabled.
Module Status (CCW Var: _IO_Xx_ST_47:32)
The module status variables used in this range are reserved for indicating
different module behaviors as listed below:
