PlcNextEngineer 2021.0.1: Error when adding Profinet station with 63 IOs

edited January 2021 in PLCnext Engineer

Hi,

I'm using the PlcNext Engineer 2021.0.1 with a RFC 4072S (FW 2021.0). I have a Profinet Sation with 63 IOs and an AXL F BK PN TPS V1.30.

In my Engineer project I added the Buscoupler from the Network-List to the RFC, configured the IP and name settings of the BK and auto read the profinet moduls connected.

All devices connected to the BK are found and correctly added to my project but I get the following Error:

"Fehler","","Internal Error : Expected position to be less than length.
Parametername: value"

When I remove the station everything works fine.

I have two other station with smaller number of IOs that make no problem.

Can you tell me what this error means? How can I add such a bis station without error.

  • Hi

    As far as i remember the Profinet Coubler takes 1 space it self.
    I think it's why it's have (64) at the end of the name of the Bus Coubler

  • I tried to make a test in 2020.6.2 with out that error.
    I converted to 2021.0.1 and also without error. There is a limit of 1024bytes in and 1024Output data....

    I don't know if you exceed that limit when you have Serial communication and safety modules included?

    Have you tried to restart the PLC next Engineer?

  • Hello, I just created a totally new project with the same effect

     

  • Hi,

    after upgrading from 2020.6 to 2021.0.1 I'm getting the same error, but everthing was running fine with 2020.6. Our controller is the AXC F 2152 and we do use a AXL F BK PN TPS too.
