10.4.2 On-Line Error Codes and Status Codes
These codes can be produced while the controller is running function block and may be actively controlling a
process. Depending on the message and its priority level, user intervention may be required or the message may
simply be informational in nature. Parameter “SE” located at Modbus register $40002 will reflect unacknowledged
error or status messages present in the controller. Messages are displayed according to priority until all active
messages have been acknowledged. If no link code has been assigned to the active message, the “SE” code will
remain at its last value.
Table 10-2 lists on-line error and status codes. For most error codes, replace the involved circuit board to repair the
controller. For most status codes, acknowledge or otherwise respond to the situation.
