. Why the RS-485 S-Bus communication between the PCD master and the slave does fail sometime, if FW 1.28.20…1.28.33 is used? (FAQ #102026) It’s possible that the some of the S-Bus telegrams transferred from the PCD S-Bus master to the S-Bus slaves over RS485 are malformed, and the S-Bus slave does reject the request from the master. This could lead to the situation that for example the PCD S-Bus master don’t receive actual values from E-Line RIO’s or that the program download of a PCD program from the PC to a Slave PCD which is
