PowerFlex400 with CompactL L32E comms ERROR

[jorgeGal]

Hi, I have this configuration and I´m receiving 203 (timed out) error from the I/O tree in RSL5000. Although, I can read parameters from the drive. I tried changing the RPI parameter, from 20ms to 30ms with no results.
The VFD is connected by a wireless network to the PLC. I have unmanaged switchs in both sides.
Where should I start to check this issue?

First, try increasing the RPI to a relatively large value, like 200 ms.

Unless you have a very good reason to use a wireless IP network, I strongly recommend against it.
