7.1.4.1 Introduction
Interface to unit and to equipment module
In SIMATIC BATCH, each unit and each recipe phase of a control recipe communicates at
runtime with a unit and an equipment module in the automation system. Both setpoints and
process values as well as the current status or control commands are exchanged. An
equipment module may be an equipment phase (EPH) or an equipment operation (EOP).
SIMATIC BATCH can use the new functionality of the SFC types in the engineering system.
As an alternative for reasons of compatibility, SIMATIC BATCH also continues to provide
BATCH interface blocks as the communications interface to the processing programs on the
automation system. These blocks are implemented as CFC blocks and are installed during
the SIMATIC BATCH setup.
BATCH interface blocks/unit
A CFC chart is created for each unit and contains an instance of the UNIT_PLC block with
assigned parameter values.
BATCH interface blocks/equipment phase
Communication between SIMATIC BATCH and the equipment phases in the automation
system is implemented using own interface blocks (IEPH, IEOP and IEPAR_xxx). An
equipment phase is implemented with the IEPH block and an equipment operation using the
IEOP block. They are interconnected with the appropriate inputs/outputs of the SFC control
block and technological blocks according to the process cell requirements in the CFC charts.
