Page 12: Switching Functions
SIO mode: 1 switching input DI1 (Z BCS1). Switching input positive switching (PNP) – Auto-drop function: the ejector pulse is generated after the signal change “Suction” (BCS1).

Page 14: Monitoring And Diagnostics
The monitoring functions are activated at the factory (except for monitoring of the evacuation and air supply times). The time monitoring can be activated through setting of the critical limit values SP1 (evacuation time) and SP2 (air supply time) in BDC4 è Smart Sensor profile parameters Festo — OVEM-...-LK — 2019-03c... -
Page 15: Measured Variables
SP1 by BDC1 or BDC2. The air supply time t is measured from the start of air supply to the time at which the pressure value (vacuum) falls below -50 mbar. Festo — OVEM-...-LK — 2019-03c... -
Page 16: Teach Function (Teach-In)
Simplified Teach commands “BDCx Start” (Start Teach), “BDCx Stop” (Stop Teach) can be used independently of the switching function. The sequence of the teach points must be taken into account. – For all commands, the desired channel must first be selected. Festo — OVEM-...-LK — 2019-03c... -
Page 17: Data Storage
Transfer of block parameters through start and end commands è Command code – During transfer, parameter changes (e.g. through teach-in) are blocked. – In case of an invalid parameter set, the changed parameters are discarded and the previous para- meter set is reactivated.
