INTERBUS CMD (Configuration, Maintenance and Diagnostics) software clearly displays INTERBUS system information. In order to guarantee packaging quality in the case of a conveyor jam, for example, it must be possible to switch-off individual belts within a specific time, working back from the location of the malfunction. Switch-off is done through CMD, and the conveyor restarts automatically and runs normally following correction of the malfunction. PREVIOUS SOLUTION The old, conventional contactor control system was initially replaced by a PLC in order to achieve the required level of flexibility. Tea cartons reach the final packaging station, which is also controlled by INTERBUS. RESULTS/BENEFITS SUMMARY For reasons of time, the usually complex and cost-intensive parallel cabling was replaced by a modern automation system based on INTERBUS, greatly reducing the amount of cabling required, as well as the related labor and material costs. INTERBUS also made possible the separate, time-saving testing of each prefabricated, decentralized subdistribution boards. INTERBUS support of the decentralized contactor scheme also saved considerable implementation time, one of the principal reasons for this company’s decision to adopt INTERBUS as its networking standard.
