 Option Low Priority Alarm Codes
These codes are transmitted as Manufacturer Specific Diagnostic low priority alarms that can be seen in the PLC
configuration software. These low priority codes are the same codes that appear in the drive manual, except with an
offset of 0x1000.
Table 25 PROFINET Option Low Priority Alarm Codes
