  1. Hello, I have an issue reading the values of HSC by Ignition SCADA. PLC type: SM35-J-R20. Shortly, there is a simple logic calculating the total output from the machine, PNP proximity sensor is used to measure the number of the passing products, and it is connected to HSC input of the PLC. SCADA monitors the current and the previous value of the counter, and in case the counter has been reset when the batch is being changed (the previous value is bigger than the current value), the previous value is memorized and it is added to the current counter value, at the same time a tag val
  2. Hi all. For a few years, I have been using the HSC frequency measurement on the V350. My program uses the example that was given by Unitronics and I have not altered it much. Suddenly, my programs have stopped working when I download them to a new PLC. The HSC behaves unusual and gives me false readings. My program is to control micro water turbines and it uses HSC to measure the frequency of the generator. I am using a simple frequency converter that gives me pulses into my HSCO port. The pulses are 50Hz and I confirm using a digital meter that the input receives 50Hz.
  3. 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
  4. Hi everyone! Is there any way to reset the MI associated to an HSC input by software? The problem is that if I don't do that, it will overflow. Thanks in advance, Gonzalo PS: I'm using a V350
