Logical functions implemented in SIMEX Multicon CMC-99 makes simple control procedures available. Depending on tanks level our device switches batch valves. After finishing whole sequence our controler switch the pump on. Those levels are seen on CMC-99 screen. There is a possibility to implement some outputs as an alarm signals. There are simple controler and HMI unit collected in one single device. There is no need to create visualization aplication and control procedures separately.
