LOCATION_INV_SYNC
Storage-location map and inventory reconciliation — refuses double allocation, counts from the map, and flags WMS mismatches for cycle count.
When to use it
Use LOCATION_INV_SYNC when the floor holds its own picture of which storage locations are empty, reserved, occupied or blocked, and that picture has to stay in agreement with the WMS inventory for a zone of up to 64 locations.
Interface
The published port signature. This is the whole of what the block exposes to your program — the implementation body is not shown here and ships with the download.

Download LOCATION_INV_SYNC — free
Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
