Problem with displaying online on PC. Everything is fine on the master, but on the slave the display of variables online is very very slow. Sometimes it can’t even upload changes(. I connect via field PG and a CP card. But with the MPI/DP adapter it’s the same. What’s the problem? Does the slave have priority? Attachment Untitled.png (157 Downloads)

The PLC uses the X2 DP connector. Firmware PLS has been updated to the latest 3.3.17. When you make him a master, the online works great, but as soon as you make him a slave, the online slows down.

STEP 7 V5.7 SP2 Trial Download -> can also be used as update to SP2, existing license unlocks the trial Download Hotfix 1 STEP 7 V5.7 SP2 / STEP 7 Professional 2021 SR2 -> after installation of SP2 Maybe this helps. regards sancruz
