5.8 ProSoft gateway Troubleshooting

When doing detailed trouble-shooting, ProSoft Technology’s engineering and

technical support group uses MMS Ethereal. With it, the stream of data can be

analyzed, from both the IEC 61850 and Modbus TCP/IP points of view. Looking

at the data in this way may be useful when troubleshooting.

ISO 9506-1:2003 and ISO 9506-2:2003, along with RFC 1006, make up the

protocols used for MMS (IEC-61850-8-1).

Example screen snapshot:

This is an IED responding to a MMS request with an object-non-existent error

(code = 10).

These are the possible Data Access Errors, from ISO 9506-2:

DataAccessError ::= INTEGER {

object-invalidated (0),

hardware-fault (1),

temporarily-unavailable (2),

object-access-denied (3),

object-undefined (4),

invalid-address (5),

type-unsupported (6),

type-inconsistent (7),

object-attribute-inconsistent (8),

object-access-unsupported (9),

object-non-existent (10),

object-value-invalid (11)

} (0..11)
