Problem with CANOpen in Weintek-Lenze communication

[krewak]

Hello everyone,

I have Weintek HMI and three Lenze power inverters which should communicate with HMI via CANOpen. I have no problem with PDOs, but when I try to use a SDO, some kind of error occurs.

For example: I have two numerical displays and I want to show value of DC on inverter (variable 5FCA) and temperature (5FC2); details are irrevelant, because problem occurs with every variable.

It seems that everything is OK with addresses, but on running HMI screen it looks like these two variables overwrite each other. Both displays show mainly DC value (558-563V) and sometimes they "switches" to the temperature (24-27*C).

Thanks to PCAN-View I know that inverters read and send everything without any problem and error occurs on HMI side. Does anyone of you had a similar problem? At this moment I'm downloading older versions of EasyBuilder Pro for Weintek HMI, but I'm running out of ideas.

If someone would have been interested with that problem in the future, I found a solution. It was the simplest thing in the world, because software update to Easy Builder Pro 4.10.5 helps with mentioned SDO errors.


Another thing is that I still have another problems with PDO, but this is question for another thread.
