3-1 Setting a Bit (Contact)
Example: Setting the Basic PID block’s R/L Switch from Monitor Plus
The following steps are required to set a bit’s status.
1,2,3...
1.
Write the data to the CPU Unit’s data area from Monitor Plus, read this data
with the Internal Switch (Block Model 209), and write it to the Loop Control
Unit or Board’s internal memory.
2.
Use the Contact Distributor (Block Model 201) to input the data (written to
internal memory in step 1) to the function block’s bit. In this case, the bit
data is input to the Basic PID block’s Remote/Local Switch ITEM.
3.
Set the tag for Monitor Plus (used to set the bit from Monitor Plus) in the
Internal Switch’s bit. In this case, S1’s tag name is set to RLSW.

(Feedback from
the whole system)
These function blocks set or monitor
bit data from Monitor Plus.
