3.4.4 Recipe levels and sequence of a recipe
Recipe levels and recipe logic
In AS-based mode, SIMATIC BATCH allows a reduction and a reproducibility of step change
times with the following recipe control runtime functions that have been shifted to the
automation system:
● Unit/RUP level
● Recipe level 1/ROP level
● Recipe level 2/RPH level
● Logic of the individual control units
Recipe level 2 / RPH level contains the recipe logic and its accelerated execution via the SFC
type or SFC chart.
The logic of the individual control units describes the user configuration on the AS.
The system blocks required for recipe control and the runtime system are grouped together in
the SIMATIC BATCH blocks library.
Recipe execution
The mapping of the recipe execution in the AS is made with the following block classes:
1. RUP level -> UNIT_PLC block
2. ROP level -> EOP block (level 1)
3. RPH level -> EPH block (level 2)
Recipes in the automation systems are assigned to the units as control recipes. This property
allows the distribution of a project over several automation systems.
If communication with the SIMATIC BATCH control server is interrupted, the AS continues to
run to the next synchronization line in the recipe or to a reference (transition or command block)
to another unit recipe. Events are temporarily stored on a unit-specific basis until the configured
communication buffers are full.
The volume of data that may be put into interim storage depends on the corresponding volume
of batch communication.
