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.
