Modifying the motor module - overview

In a previous procedure, you created the MTR-101 module in DeltaV Explorer by copying the MTR_11_ILOCK template to the TANK-101 area. In this procedure, you will open the module for editing in Control Studio. This module looks complex at first, but it becomes more understandable as you look at the individual parts.

The motor module, shown later in this procedure, includes the following function blocks, all of which are on the Logical palette:

• Eight Condition (CND) blocks

• Boolean Fan Input (BFI) block

• Logical And (AND), logical Not (NOT), and logical Or (OR) blocks

• Device Control (DC) block

The CND, BFI, AND, NOT, and OR blocks are used to specify the interlock logic. The DC block is for motor control.

Some of the things you will do in this procedure are:

• Delete the five excess condition blocks.

• Specify the interlock conditions using the remaining three condition blocks.

• Specify the Device Signal Tags for the input and output parameters.

• Change the detail display associated with this module to one that has three conditions rather than eight.
