Hi guys, hopefully someone here has a logical explanation for me on this one. We ran some Cat6 cable from a HMI (Proface) to a switch about 50 meters away, that was connected to a laptop (from the dumb switch) for remote viewing. On the HMI side we terminated the cable with a normal RJ45 plug connector which went into a dumb industrial switch in the control panel. On the laptop side we done the same going into another switch. After all this, I couldn't establish any comms from the laptop to the HMI and after a whole day messing around with this, which included cable testing using two different cable testers that showed good connection statuses.....Someone in the office suggested using RJ45 socket connectors and normal pre-made patch leads from there on both sides. I wasn't convinced that this would work but was willing to try anything and done it, after we changed the connections over the comms worked immediately without issues. I've been working in the automation industry for a while now but haven't seen something like this before, does anyone have a logical explaining for me???
