Maintenance messages
The I/O module generates a maintenance message for the following events:
• Redundancy partner has dierent hardware/rmware version
• IO redundancy warning
• Carrier module or memory in carrier module is defective
• Terminal block (TB) or memory in terminal block is defective
• Internal temperature limit reached
• Internal malfunction of HART communication detected
• In addition, all HART diagnostics are reported as maintenance messages.
You can nd more information on this in the section "Maintenance events (Page 72)".
