dugono Posted July 27, 2018 Report Share Posted July 27, 2018 Hi all, I'm new to this forum and wish to pick the brains of anyone that could suggest a fix for a very unusual problem is occurring on a vision 570 with v200-18-E3XB snap in. We have built 5 identical machines that are essentially batch fillers using the vision 570 with V200-18-E3XB. All machines have identical programs. We have a flow meter that pulses out 1 pulse for every gram of product or about 25 pulses per second. we feed this pulse into the HSC and totalise until the desire value is reached . simple! except one of the machines counts for a while , say a minute or two, then the plc decides to stop counting. the counting doesn't just stop , it ramps down to zero over a period of say 5 seconds. when this first occurred I check the wiring from the flow meter to the plc with a digital counting multi meter and all was good . It was then I noticed one of the connector block on the digital inputs wasn't all the way in . about 2 mm out . I pushed it in and the problem disappeared. problem solved I thought! but the the problem has come back and the connector blocks are all seating well. has anyone come across bad soldering on connections of input terminals on this product or know what else it could be ?
