Please note the following requirement for displaying the tag values on the CPU display:
You must specify a symbolic name for each tag in the "Name" column of the force table.
You monitor the following operand areas:
– Inputs and outputs (process image) and bit memory
– Contents of data blocks
– Peripheral inputs and peripheral outputs
– Timers and counters
● Modifying tags
You use this function to assign values to the individual tags of a user program or a CPU
on the PG/PC. Modifying is also possible with Test with program status.
The following operand areas are modifiable:
