7.1.6.1 Creating and inserting user process tag types in CFC charts
Introduction to creating and inserting user process tag types in CFC charts
There are two ways to collect measured values, for example to form transition conditions:
● Using the BATCH interface block TAG_COLL (as in BATCH
● Using the standard function block TAG_COLL, given the name TAG_COLLECT below to
distinguish the two (new in SIMATIC BATCH as of V6.0)
Individual measured values are created in the interface or standard function block. The process
tag types are then generated in the BATCH configuration dialog within the context of the batch
types ("Generate" button) from the TAG_COLL/TAG_COLLECT blocks.
Using the TAG_COLL BATCH interface block
When using BATCH interface blocks, the TAG_COLL block is used to collect process values
to form transition conditions and for archiving and report creation of measured values: For a
description, see section Rules for the TAG_COLL interface block (Page 161). The process tag
types that are then generated can be further processed and modified in the BATCH
configuration dialog.
Using the TAG_COLLECT function block
If you configure with SFC types it is advisable to configure a TAG_COLLECT standard function
block to collect process values. The process tag types that are then generated are read-only
in the BATCH configuration dialog. Modifications to the process tag type can only be made in
the function block. These are then adopted in any existing instances. After modification, the
batch types and the process tag types must be generated again.
Note
Points to note:
● To allow a TAG_COLLECT FB/FC type to be read into the BATCH configuration dialog
(generated) for the process cell, an instance of the TAG_COLLECT must have been created
at least once in the CFC chart.
● FB types are unique only within an S7 program or a CPU. For Batch configuration, however,
the uniqueness throughout the entire project or the multiproject must be ensured.
7.1.6.2

First option: Create new function block

There are two ways of creating process tag types:
● Option 1: A new FB is created immediately.
● Option 2: A new CFC chart is created and then compiled as a block.
