CP Kelco recently installed Valmet DNA to replace an end-of-life automation system on CMC production line 4 in its Äänekoski facility in Finland. New technology was a key part of the delivery including Valmet’s first redundant PROFINET extension to DNA for motor controls.
|Challenge||“We already had good PROFINET experience with PLCs in the plant and will soon be facing the replacement of I/O hardware dating back to 1992. As the motor control cabinets on line 4 needed upgrading we decided it would be a good opportunity to test PROFINET solutions on a larger scale, and give us another alternative for future upgrades,” says Rönkä|
|Solution||Redundant PROFINET implementation|
|Results||“We now have the ability to reset tripped motors from the control room, read information from the controller, like the number of starts and have real time diagnostics information. A big benefit of the redundancy is the possibility to replace a motor control module on the run without stopping the process,” declares Rönkä, “Earlier that might have caused a problem.” The PROFINET ring is active all the time with a spare PROFINET switch connected to the ring that can be taken into use without reconnection of the PROFINET cable.|
