Engineering technology
In SIMATIC Manager, the central place for configuration is Basic and BATCH engineering.
You create the enumerations and control strategies for your project in the global declarations.
The unit block "UNIT_PLC" was extended by the new inputs "UnitStatus" and "L_UnitStatus".
These inputs have "S7_Enum" attributes and can be linked to a set of enumerations. All units
in the same unit class must be connected with the same enumeration. The "UnitStatus" input
can be modified by a PCS 7 OS or by means of the SIMATIC BATCH batch control. The
"L_UnitStatus" input is coupled with the user program in the AS and you can use it with its own
logic. The "En_LinkedUnitStatus" input blocks the "UnitStatus" input and activates the
"L_UnitStatus" input. The "Q_UnitStatus" block output shows the current status of the
corresponding unit.
You use enumerations at the "UNIT_PLC" block "UnitStat" input. You can use them to define
a status for a unit with a parameter step of batch control.
You use control strategies at the "IEPAR_ENUM" block, for example, at the "SP_VAL" input.
To do so, the "EPE_CONN" output of "UNIT_PLC" must be interconnected with the input of
the same name at the "IEPAR_ENUM" block. You use batch control to define and continue to
use the control strategy at the "SP_VAL" input.
The control strategies of equipment properties are assigned to the corresponding parameters
(IEPAR_XXX) in BATCH engineering. Only the selected control strategy parameters are then
taken into consideration during batch control. After generation or propagation of the BATCH
types, the compilation or merging of batch instances and the download of the batch process
cell, the global declarations are available for recipe engineering in the recipe editor after
updating your batch process cell.
User interface
The setpoint and the current process value are displayed in the unit faceplate of a PCS 7 OS.
The displayed parameters are filtered according to the selected allocation strategy, if available.
Similar to the setpoints of recipe functions (EPH, EOP), you can change the setpoints for
dynamic units using the faceplate.
Requirement
You are using the current block types from the SIMATIC BATCH block library in your project.
Check to see if the unit block "UNIT_PLC" includes the inputs "UnitStat" and "EPE_CONN". If
the unit block does not exhibit these I/Os, you must update your block types or make the
corresponding I/Os visible.
