I recently upgraded a 10 year old S7 417H with a S7 414H but the ET200M and YLINK's remained the same. The YLINK's are still the older 157 type. My problem - although the hardware reports ok I cannot see any I/O after the YLINKS. This worked fine for 10 years. I reconfigured the hardware a few times but this has not helped. Any suggestions as to why the YLINK is not working? AttachmentYLink Problem.pdf (197 Downloads) |
