4.3 Performing block instantiation

About block instantiation

A block instance is a copy of an available block in the device, say for example AI block. There are a
total of 11 permanent blocks and only five blocks support instantiation in a device. The five blocks
that support instantiation are:

Analog Input Block

Arithmetic Block

Signal Characterizer Block

Input Selector Block

PID Block
Five instances of the Analog Input block, and one instance of Arithmetic block, one instance of Signal
Characterizer Block, one instance of Input Selector Block and one instance of the PID block can be
instantiated. A block can be instantiated or deleted.
Before block instantiation, the device checks whether the particular block is supported, and if there is
sufficient memory to store the parameters. After Instantiation, the instantiated block must be loaded
into the device, and then the strategies can be created.

Block instantiation using Experion PKS

The following are the steps for performing block instantiation using Experion PKS.
Step
From the DD at the Library-Containment window, select an instantiation
1
block from the supported blocks, that is Analog Input block, or Input Selector
block, or Signal Characterizer block.
Drag and drop the required instantiation block into the device on the Project-
2
Assignment window.
After adding the instantiation block into the device in the Project-
3
Assignment window, select the device.
Right-click the device, and click Load.
4
The instantiated block is loaded into the device.
