checksum error is detected. If the LED on the front panel is not flashing and either of the other

LEDs is illuminated, the SHIM is not operational and should be replaced.

5.3 Error Messages

This section explains error codes returned by the Smart Device Interface to the Advant OCS

System and reported as diagnostic messages on the Diagnostic Message Display.

5.3.1 Diagnostic Messages

As a benefit of the Smart Device Interface, you can continuously receive diagnostic information

from smart devices in the field via digital communications when reading the primary value. This

information is not provided with standard analog processing.

Diagnostic information retrieved from the smart device is incorporated into the Advant OCS

Diagnostic Package with details indicating which device generated the error and its logical

location in the field (that is, the Advant Controller (MVI) serial port and SHIM network

address).

The following examples show the format of the diagnostic messages generated for SHIMs:

SMART NETWORK 2 FAILED TO RESPOND ON PORT 5

SMART NETWORK 2 HAS RESUMED COMMUNICATION

The first message is generated when the wiring between the serial I/O port and SHIM is

disconnected, severing communication with the SHIM and all smart devices connected to that

SHIM. The second message is generated when the physical connection between the serial I/O

port and SHIM is re-established, resuming communication with the SHIM and all smart devices

connected to that SHIM.

Both of these messages have 2 digits reserved for identifying the network address (1-31) of the

SHIM that failed or resumed communication. The first message also has 2 digits reserved for

identifying the serial I/O port to which the SHIM is connected. This allows you to easily locate

the SHIM in field and correct the problem.

The following is an example of a communication error code returned by a SHIM:

SDI: ERROR 1 RECEIVING MSG FROM NETWORK 5

The first number in the error message indicates a communication error, and the second number

identifies the SHIM’s network address where the communication error occurred.

The following examples show the format of the diagnostic messages generated for smart

devices:

SMART DEV 201 FAILED TO RESPOND ON PORT 5

SMART DEV 201 HAS RESUMED COMMUNICATION

SMART DEV 201 SENT ERROR CODE 2

The first message is generated when the wiring between the smart device and SHIM is

disconnected, severing communication with the smart device. The second message is generated

when the physical connection between the smart device and SHIM is re-established, resuming
