Setting up the equipment module with interface blocks IEPH and IEOP

SIMATIC BATCH block library
All the necessary BATCH blocks for the two modes are contained in the SIMATIC BATCH
block library. The documentation in the form of a PDF file is available under START > SIMATIC
> Documentation > English > SIMATIC BATCH. You can obtain direct help for each individual
block with the F1 key in the SIMATIC Manager in CFC when the BATCH block is selected in
the relevant library. The BATCH interface blocks are inserted in the CFC charts by dragging
them from the BATCH block library.

Equipment module
Using the BATCH interface blocks along with SIMATIC BATCH, makes the following functions
available:
● Controlling the running of the process:
The IEPH/IEOP blocks are used for this purpose. These provide the commands (for
example start or hold) of the recipe steps from the batch control to the processing blocks
(for example: SFC external view or user blocks). The processing blocks report their current
statuses back to the batch control.
● Transferring setpoints and process values:
The IEPAR blocks are used for this purpose. The batch control writes the recipe parameters
(setpoints) for the processing blocks into these blocks. The processing blocks write the
result data (process values) to the IEPAR blocks so that they can be stored as batch data
by the batch control. The IEPAR blocks linked to the IEPH/IEOP blocks are also used to
form transition conditions.
