The drive systems are incorporated into the Maintenance Station using Drive ES PCS 7. Drive ES PCS 7 allows Siemens drives to be controlled using SIMATIC PCS 7 with standard function blocks, and operation and monitoring using faceplates in the operator station.
Maintenance with Drive ES PCS 7 can be shown using the example of a mixer drive: the material to be mixed slowly deposits on the stirrer. The stirrer was previously cleaned at pre-defined intervals to ensure its availability. Using the new functions in the maintenance station, cleaning can be carried out only when required.
Drive ES SIMATIC PCS 7 generates a corresponding maintenance display for the Maintenance Station. The mixer can then be cleaned as required. It is also possible to record the frequency of cleaning requests to derive process optimization or predictive maintenance scenarios. Maintenance can therefore also be optimized for moving plant components, with associated increases in plant availability and productivity.
The components automatically signal when maintenance is required. An example is a medium-voltage converter such as SINAMICS GM150. In this case, a differential pressure transmitter determines the degree of contamination of the dust filters and alerts the operator.
In the water-cooled version, the analog conductivity measurement continuously checks the mode of operation of the ion exchanger, and provides an early signal when its capacity is diminishing. The filters for air cleaning and the pumps for water cooling are equipped with operating hour counters that alarm you when maintenance needs to be performed
