CHB have a in house developed Siemens Robicon Perfect Harmony NXG medium voltage drive demonstrator. This can be used for training on medium voltage drives and also for factory testing of PLC fieldbus or SCADA interfaces to the Siemens Perfect Harmony GH180 drives. The following fieldbus interfaces can be tested;
- Modbus Ethernet
- Modbus Plus
- Data Highway Plus
Along with training and testing of PLC field bus and SCADA interfaces the demonstrator is used in house to functionally check all the control cards in the DCR rack. The demonstrator simulates the power cells and input medium voltage and will run just like a normal drive in the field.
