Greetings, everyone! I'm currently in the process of upgrading a monitoring program from an ML 1000 processor to an ML 1400 processor. This is the same project where I faced challenges with indirect addressing last week. I truly appreciate all the assistance; the addressing issues have now been resolved! Let me share some details about my program. I'm monitoring the current of a grinding wheel used in an engine valve seat grinder. This setup allows me to establish high and low limits. If the grinding wheel current exceeds or falls below these predefined thresholds, it triggers a reject gate for the valve, enabling the machine operator to conduct an inspection. To aid the operator in adjusting their high and low values effectively, I'm transmitting the grinding current data for the last 16 valves to a Human-Machine Interface (HMI) display. Additionally, I aim to highlight the highest, lowest, and average current values from this group of valves. However, I'm encountering a challenge: the high and low current readings consistently display values of 6244 and 0, and I’m unsure about their source. I plan to share a few screenshots of the relevant section of my program that deals with these high and low values. Does anyone have insights into what I might be overlooking? Thank you once again for your support! Best, Jeremy
For optimal clarity, please compress the entire file into a ZIP format and attach it, as this is far more effective than sending multiple screenshots.
Hello! I've reviewed the attached image and noticed that the HMI display shows a value of 6244 [N7:30]. I hope this information is helpful to you!
In your initial screenshot, referred to as Rung 1, you reset the counter C5:3 before transferring the value of C5:3.ACC to N7:70. As a result, the value will always be zero. To ensure you retain the current value of C5:3.ACC, it's essential to place the reset instruction after the Move instruction. This adjustment will allow you to capture the accurate count when moving data.
