CASE_PACKER_CTRL
Case packer count and pattern control with no-case, overcount and infeed-stall protection.
When to use it
Use CASE_PACKER_CTRL when product is counted into a case or tray to a fixed count arranged in rows, the case must not be discharged short or over-filled, and product must never be fed with no case in the load station.

Supervised control write
CASE_PACKER_CTRL commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
