I'm having major issues programming the high speed counter function on the Micro 850. I have no more avenues to pursue... I've tried everything I can think of. For the last day, I've tried using the example in the documentation to create a HSC. I followed it line-for-line, changing safe variables slightly, like mode and limits, assigning HP, LP, OF, and UF to 1200, -1200, 1500, and -1500 respectively. I can't make this work, and I can't afford any more wasted time trying to get it to function.
Here is a brief synopsis of several days of working with the Micro850
1. The HSC module works, but not with the MODE in need for this application. I downloaded the UDFB and got it to work nicely, but it only works in mode 0,2,4,6 (no odd numbers). I tried programming it in MODE 0, but I need to insert the value for HP, and then reset the Accumulated Value after each cut. I found that I needed MODE 3. For MODE 3, I need to use the embedded I/O, and the HSC function. I can not use the HSC module for MODE 3.
2. I can't get the controller to work using the HSC function in the embedded I/O. I'm using input 0, and I can see the encoder working with the input lights. But the controller faults out immediately when I download and run a very basic HSC function in a ladder. The fault is a HSC config fault. The attachments to this message show the pertinent information. I'm using the example in the documentation to create a HSC. I've tried everything I can think of. I can't get this fault to clear.
At this point, I believe it's a software bug. My customer is frustrated with me and I can't get past this issue. I've lost several days now, making this PLC not as affordable as it seemed in the beginning.
Can anybody see anything I'm missing?
Thanks,
Brian
