3-2 Monitoring a Contact (Bit)
Example: Monitoring the Basic PID block's High MV Limit Output (MHA) from
Monitor Plus
The following steps are required to monitor a bit's status.
1. Use the Contact Distributor (Block Model 201) to temporarily store the
function block's bit status in the Loop Control Unit or Board's memory.
2. Use the Internal Switch (Block Model 209) to read the temporarily stored
data from memory and write it to the CPU Unit's data area.
3. Set the tag for Monitor Plus (used to monitor the bit from Monitor Plus) in
the Internal Switch's bit. In this case, S2's tag name is set to MHA.
Set tags for Monitor Plus.
