The RoofSupportSystemType provides a representation of a roof support system as a sub-type of MiningEquipmentType as shown in Figure 1. Importantly, it is composed of a ParameterSet to monitor all relevant parameters of the equipment.
Figure 1 – Overview RoofSupportSystemType
The RoofSupportSystemType is formally defined in Table 1.

The AFCPushState Variable describes the status of the AFCPush process determined on the actual shearer position
The ClearanceLeft Variable 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 ClearanceRight Variable 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 ShieldAdvanceState Variable describes the status of the ShieldAdvance process determined on the actual shearer position.
The ShieldWidth Variable 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.
