I've been beating my head against the wall for half a day now trying to get the CTRL_HSC_EXT instruction to work to simply measure the input Frequency of input I0.0 on a S7-1200 CPU 1214C PLC (Firmware V4.2) but no matter what I do it always reads 0 Hz. Has anyone else had any luck with this and have an example or advice on what I could be missing? I've read and re-read the system manual's description on how this should work and believe I have done exactly what it talks about with no luck. AttachmentCTRL_HSC_EXT.pdf (836 Downloads) |
