Is it possible to active many homing MFBs at the same time, on different Lexiums / ATV connected on CANopen?
Issue:
Some customers observed unexpected behavior of their Lexium/ATV when they proceed many Homing MFB at the same time (activated during the same MAST task).
Product line
M340, CANopen, MFB Homing, Lexium, ATVxxx
Environment
All versions of UnityPro & Control Expert
Resolution
Lexium & ATVxxx are commonly driven by BMXP3420102 or BMXP3420302 CPU CANopen Master.
We have identified an issue, when many Homing function are activated simultaneously.
This issue is due to the fact that each Homing MFB, when they are processed by the PLC, generates in background, one or many explicite messages (Write-SDO) per slave.
This issue is fixed in version in OS >= SV3.20 of the CPU BMXP3420102 or BMXP3420302.
When using an OS < SV3.20 of the CPU BMXP3420102 or BMXP3420302 we recommend to arm only one Homing MFB at the same time.
