From a PLC programmers perspective, which Hardy Instrument should I use with my PLC? The HI 3030, HI 4050, HI 2151/30WC, HI 2110WI, the HI 200 DeviceNet module or one of the PLC plug in modules?
After running a TARE command on my Hardy PLC module, my system loses power. When it powers back up, the Net weight is a different value than when it lost power. What is happening and how do I prevent the loss of my Net reference point?
I have an older HI 2151/20 and want to upgrade to a current model. Is the HI 2151/30 WS the direct replacment?
What steps are necessary to replace a HI 2151/20WC with a HI 2151/30WC?
We recently experienced three instances where our HI 1756WS module had a steady red OK led. We reset it by removing it from the PLC chassis and plugging it back in. Do you think my HI 1756WS is faulty, or could this problem be caused by something else?
After resetting the module in this manner, why do we need to do a calibration to get it to weigh correctly?
