Upgrade of control system of grain drying complex due to the need of technological change: dry grain by passing it sequentially through each of the drying towers. Added second S7-1200 PLC as a remote IO station. Added new mechanisms: bucket elevator, conveyor, valve and changeover valve. The list of possible routes extended, the third route channel is added. SCADA performance improved, interface updated (larger fonts, intuitive dialog windows, additional controls and prompts for the operator etc).
