BUS-LED 5-1
Maximum input data length exceeded (Fault code 5, argument 1)
Wago · Modular I/O System PROFIBUS DP
¿Qué significa BUS-LED 5-1 ?
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.
Causas comunes
- The number of connected input modules exceeds the coupler's maximum data capacity
- Total configured input data length is greater than 128 bytes (or 244 bytes for SW 03+ firmware)
