Due to different bus loads, the timing is cannot be guaranteed and predicted. In lab environment with 64 Panelbus modules a drift of the internal model to the real valve position of 5 % drift per hour was observed, while on a small Panelbus with one XFR824A the drift was only 0,02% per hour...
Typically this doesn’t have an impact on the control quality, if both over-travels are allowed in both end positions. If the correct feedback position is required for display purposes, a synchronization run with the SYN-02, SNY-03 and SNY-04 is recommended.
