Hi, I have found this forum extremely helpful in the past. I greatly appreciate in advance any help/direction. I am having trouble simply placing/invoking a PRV instruction in CX-Programmer. The program seems to not recognize really any of the High Speed Counter instructions. (working with a CT021. I/O table correct, CJ2H CPU67 PLC rack powered on with all green lights.) Please see attached screenshots for what I mean... the PRV, PRV2, CTBL, SPED, etc instructions just show up red (like they are not understood/recognized PLC instructions/functions) when I try to place in the ladder. There must be something simple that I am not considering. Thanks again for any help. Michael

Hi, I am planning to use an encoder on a CP1L to read on the RPM of a spinning wheel. For this, I can use high-speed counter 0, and the PRV2 instruction. My problem is that I also need the rotation direction. I was wondering if anybody had a tip for this? Thanks
