Technical support / adc input programming support
« on: April 20, 2010, 10:16:14 AM »
I am currently trying to use the t100md888+ with a 1616r board to control some hydraulic actuators. I am currently using NO, NC pressure switches that are set as two on each line for actuator in and actuator out. (total of 4 pressure switches) Reason for this is that I needed some form of hysteria, meaning I want to control the pump off at a certain pressure and back on at another pressure since no actuator is prefectly sealed.
I am now hoping to upgrade to pressure transducers. There are of 4-20ma type and I understand the hardware installation. However I am looking for the logic or rather the programming instructions. I am familiar with the simple inputs and outputs, virtual relays and timers, but I don't know how to get a value from the tranducer to control a digital output. Any examples would be great. Thank you in advance.
