Good day
I recently Changed a screen on a Machine from OP7 to KP400 Comfort using TIA portal v12.
since the change the communication is a bit of a issue, it is running on a palletizing machine and if 3 specific motors (and only those 3) run The communications cuts out totally. All the motors run on VSD's and at different speeds.
This looked to me like a "noise" problem
I have tried the following:
1. Cleared the PLC and screen and reloaded both
2. Replaced the MPI cable with a better screened wire (6 core twisted pair with 3 screens) connecting only one side of the screens.
3. Removed the comms wire from the electrical cabinet and ran it outside and away from any possible source of noise.
4. Installed a ferrite on one side and the on both sides.
5. Deactivated the other port on the HMI.
but I get no change to the problem.
If someone had a similar problem before and could point me in the right direction I would much appreciate it.
Thanx
