This test function returns the condition of a selected operand (inputs,
outputs, flags, data word, counters or timers) at the end of program-
execution.
This information is obtained from the process image of the selected
operands. During the "processing check" or in operating mode STOP the
periphery is read directly from the inputs. Otherwise only the process image
of the selected operands is displayed.
Control of outputs
It is possible to check the wiring and proper operation of output-modules.
You can set outputs to any desired status with or without a control program.
The process image is not modified but outputs are no longer inhibited.
Control of variables
The following variables may be modified:
I, Q, M, T, C and D.
The process image of binary and digital operands is modified independently
of the operating mode of the CPU.
When the operating mode is RUN the program is executed with the
modified process variable. When the program continues they may,
however, be modified again without notification.
Process variables are controlled asynchronously to the execution sequence
of the program.
