The AFCPushStateVariable describes the status of the AFCPush process determined on the actual shearer position

The ClearanceLeftVariable describes the length of the safe zone on the left side of the shearer. There is no risk of collision between the shearer and the RSS in that zone.

The ClearanceRightVariable describes the length of the safe zone on the right side of the shearer. There is no risk of collision between the shearer and the RSS in that zone

The ShieldAdvanceStateVariable describes the status of the ShieldAdvance process determined on the actual shearer position.

The ShieldWidthVariable describes the width of the shields including the gap between the shields.

Please refer to OPC 10000-100, OPC 40001-1, OPC 40560 and OPC 40565-1 for the descriptions of other inherited instance declarations.
