12.6 How are transfer parameters configured and used?
Introduction
Transfer parameters use locations of the type "LOCATION" (Source, Via, Dest). The term
"location" denotes input and output points in units, for example, the outlet valve of a tank.
You can select a previously defined location in a recipe as a transfer parameter and continue
to use its unique value in batch mode in your automation program.
Configuration
1. Locations are created as an equipment property of data type "LOCATION" under equipment
properties in the global declarations in the SIMATIC Manager. The settings "Source", "Via"
and "Dest" (destination) are provided as additional properties. A location can have all
properties (Source, Via, Dest).
2. In the equipment properties of a unit (Plant view), you create a new instance of the location
using a new equipment property. Assign the global location under type in the object
properties. Now the object is instantiated and given a system-wide unique value or a
number.
3. Open the SFC type or the interface block of the corresponding technical function in which
you want to use the transfer parameter. Create a new setpoint in the characteristics. In the
new declaration line, assign a name and select the appropriate transfer parameter in the
"Data type" column. The block is supplemented with the new inputs/outputs when the CFC
chart of the technical function is updated.
4. Once the engineering of the AS, PCS 7 OS and BATCH is completed, you can use the
defined transfer parameters when creating recipes and assign the instanced locations.
Result
In batch mode, the value of the location is written to the corresponding technical function by
the transfer parameter. The pending value at the corresponding block output can be used, for
example, for route control using SIMATIC Route Control.
