Ørum & Jensen PS4 ID:33

Interface Description

IGSS32 offers an interface for Ørum & Jensen PS4 equipment using COMLI protocol. COMLI is a master slave protocol that can be used in both point-to-point and in multidrop configurations. The IGSS32 driver implements direct point-to-point, dialled-up and radio connections to PS4 equipment.

PS4 equipment is specially designed for failsafe and maintenance-free control and supervision of pumps and pump-stations. PS4 is being used in waste water plants, waterworks and other industries using level control based on pressure measurements

The communication interface is also capable of reading historical sampled data in PS4 stations, thus making it possible to make reports and show graphs of signals stored in the PS4 even though it is not directly connected all the time (e.g. in dialled-up configurations).

The IGSS32 system polls the PLC equipment cyclically according to one of four user-defined time intervals. The time intervals are configurable from 100 milliseconds to 999 seconds. The system automatically groups process data in data blocks – thus fully exploiting the the communication link in relation to the present configuration.
