draganjr Posted July 26, 2021 Report Share Posted July 26, 2021 Good evening. What I have is a SM70-J-T20. We are using it has a Batch Counter with two inputs and one output. See attached PLC file and Drawing. Input I:8 is used for a forever counter, never resets till it reaches the 8th digital. Input I:9 is used for the Batch Counter and when reached a preset number will activate the Output (sprayer). The problem. I need to convert I:8 into a Hi Speed Input and wire it accordingly. I need help with that. I did leave the original counter and sensor has a backup if we lost the HMI/PLC. The original sensor is unknown but it is a PNP. The new one for the I:8 input is a Sick PNP IME18-05BPSZC0S. When looking at the counters the new counter falls behind in count, example after a week of running the new sensor will fall behind about 1 feet. We are counting in feet on our press. SO over time it will continue to fall back. The two sensors are mounted on the same bracket but separated about 1 3/4" inches from center of each other. Because they are unshielded. Thank you David Taiyo5BatchCounterV2.vlp Quote Link to comment Share on other sites More sharing options...
