    Frage PloGGIO Block - IEC 61850 with Alstom Micom P443/P444

    Hi everyone,

    I must send command with 61850 to Alstom Micom p443. I want to use PloGGIO block for that. However I can not find when i am importing to editor. I can see and control that block with IED Scout. Also try importing from .cid file, I can see PloGGIO Block. After Importing from .cid, variables are invalid. 

    I try to change driver setting. No change.

    How can i see that block in zenon editor.

    Thank you.

    Probably this Micom device is configured (or it's Firmware is supporting) only smaller size of PDU (MMS frame) as the size of the PloGGIO description. Then in Wireshark you will see - during association - that when iec850 driver requests the description of PloGGIO the device responds with ErrorPDU - is unable to deliver it. This is a mismatch between device's Hardware/Firmware possibilities and the SCL Data Model - made abstracting from this limit.

    To workaround this issue in IED: you may try to activate in driver configuration the setting 'GetNameList on DO'. This will significantly slow the importing process in Editor (and the association in Runtime) but may help to establish connection to objects in PloGGIO too.

    BTW, in zenon version 8.00 (and in latest builds of 7.50 and 7.60) we have enhanced the IEC850 driver with extra procedure: when IED responds ErrorPDU, then the driver tries to workaround it automatically. So, this setting in driver has been removed. Also the procedure used by driver has been optimized to make this workaround faster.
