CONFIGURATION
Figure 4 .10. PID_OH1 Compound
The compound has the following function blocks:
Block Name Type Description
pid PID The PID control block
PV VCIM Voltage/Current Input block used for PV
Pv_i VCI Voltage/Current Signal conditioning for the AIN
op_ao AOM Analog output block
RETURN VCIM Voltage/Current input used to get the feedback from
the output holder. Configured as 1-5 mA
RETURNF1 VCI Signal conditioning for the AIN. Configured as 0 – 100
%
SENSE DIM Digital input to sense the presence of the output holder
SENSEF DI Signal Conditioning for the DIM block
OP_T_LGC EX Logic for bumpless transfer
Table 4-1. PID_OH Compound
There is also a Notes block that has text that explains how to use this compound as
shown in the Figure 4-4. This compound can be used as it is.
You may need to make the following changes depending on your process application:
1. The compound uses a Voltage/Current Input module (VCIM) block configured as current
input (4-20mA) and a VCI block for ranging it to 0-100 engineering units linear. It also has
an analog output module (AOM) block. You can substitute different type of input or
module, conditioning and analog output blocks
2. The compound also has preconfigured PID block, which you can substitute with your
existing PID block in your database.
