Just started using Crouzet PLC function block programming. I have the basics but I am having trouble writing a step that uses a 4-20mA signal (ultrasonic tank level sensor)and calls via modem when the level drops below a fixed level after it begins to fill. This would only happen due to evaporation or a leak. The process is a batch process so the tank should never decrease in level until it is processed by the operator.
thanks to anyone that can help.
