10.4 ERROR CODES
This section describes off-line error codes, on-line error codes, and on-line status codes. Typically, a code will
point to a failed internal assembly or a failed peripheral device. Note that a configuration error can also cause an
error code or multiple error codes to be produced. For example, an error will occur when attempting to run a
configuration that includes an I/O Expander board hardware I/O block (i.e. AINU 1, AINU2, DINU1, DINU2,
ROUT1 or ROUT2) in a controller that does not have an I/O Expander board installed.
10.4.1 Off-Line Error Codes
Off-line error messages are displayed while the 353 is powered but not running function block code and therefore
not actively controlling a process. Depending on the message, user intervention will most likely be required.
Corrective action can be initiated via the Ethernet or Modbus ports as appropriate. Parameter "SE" located at
Modbus register 40002 will contain the hexadecimal form of the error number currently displayed (e.g., ERR: 213
would be sent as $00D5). An Error message can be acknowledged over the network by writing a 0 to the Modbus
register. Messages are displayed one at a time, in order of occurrence, and a message cannot be cleared until the
error condition is corrected.
