Wago · Modular I/O System PROFIBUS DP
The total length of input data configured for the Fieldbus Coupler surpasses the maximum allowed limit (128 bytes, or 244 bytes from SW 03 onwards). This suggests that too many input modules are connected or their input data structures are excessively large, overwhelming the coupler's capacity.
Click steps to track your progress.
Switch off the supply voltage of the coupler.
Remove some I/O modules from the node to reduce the total input data length.
Switch the supply voltage on again to restart the coupler.
