Typical Problems and Failures

Communication Problems

Packet loss — damaged Ethernet ports, isolation transformer problems
Communication timeouts — oscillator failures, clock circuit problems
CRC errors — damaged RS485 transceivers, EMI interference
Bus collisions — termination problems, damaged repeaters
Jitter and delays — switch problems, network overload

Port and Interface Failures

Port burnout from surges or lightning
Ethernet transformer damage
PHY (Physical Layer) IC failures
SFP module problems — no detection, optical errors

PoE Power Problems

PSE (Power Sourcing Equipment) circuit damage
PoE port overload
PoE/PoE+ power negotiation problems

Safety System Failures

No emergency stop reaction — safety output damage
False alarms — sensor problems, interference
Self-test errors — watchdog test failures, memory problems
Loss of certification — after unprofessional repair or modification
