Notes for Accumulation Control Bits
Bit 8 – Accumulate Adjacent Upstream Zone
Setting this bit will cause the next upstream zone of the local module to accumulate. This next upstream zone can be either on the local module or the downstream zone of the adjacent upstream module.
Bit 9 – Set Arrival Confirmation for Downstream Zone
By default, for ZPA operation, ConveyLinx requires a confirmation from the downstream zone when a Carton is discharged. Without this confirmation, the releasing zone will detect a jam condition. This bit is used in applications where the Carton is removed from the conveyor (either manually or say by a PLC controlled external mechanism such as a pusher or diverter) and the PLC needs to “confirm” the removal of the Carton in order to satisfy the ZPA confirmation logic.
Bits 10 & 11 – Jog Controls
These bits can be used by the PLC to jog the local zone for specialized applications when local movement of the Carton on a zone is required. An example would be once a Carton has arrived in the local zone, the PLC determines that the Carton needs to be re-positioned or perhaps squared up against a PLC controlled pop-up stop.
Bit 12 – Wake Up Local Zone
Setting this bit will cause the local zone to “wake up” and run to accept a carton the same as if it’s upstream ERSC had written a status value of “4”. This function would be useful for a merge onto a main line of ZPA conveyor.
Bit 13 – Enable Maintenance Mode
Setting this bit will place the local zone in maintenance mode. In this mode the motor will not run regardless of zone conditions. The zone upstream of this local zone will receive a “busy” status to inhibit release of any item into this local zone. While in this state, the SEN and Motor LEDs will flash on and off in green color.
