About this Chapter

In this chapter all MicroSCADA status codes are listed. Some possible reasons why these status codes appear are also presented. Status codes are divided into the following sections:

3.1

Status codes that indicate reliability of data.

3.2

Status codes that are related to the MicroSCADA base system.

3.3

Status codes that are related to communication and NET units.

3.4

Operating system status codes.

3.5

Data transfer status codes

3.6

Status codes transmitted by a NET unit to external devices

SUSPICIOUS_STATUS

The reason why the value is uncertain may be:

•

The value of a data object is uncertain, if the sampling has failed and the logging function is other than DIRECT or DUPLICATE.

•

The element in the vector, resulting from the vector functions HIGH,

LOW, SUM and MEAN, has status 1 if all the elements in the argument vector do not have status code 0.

•

An element in the vector obtained with the vector function

CUMULATE has this status, if all the elements used for calculating it do not have status 0.

•

If a vector operation is done and the operands do not have the same number of elements, the results of odd elements get this status.

•

If all elements in a vector operation or function do not have status 0, the resulting element gets status 1.

•

A process object gets this status when the S.P.I.D.E.R. RTU has marked the process object value faulty.

OBSOLETE_STATUS

The OV-attribute (BI, BO, AI, AO, DI, DO, DB, PC or BS) gets this status when the connection to the concerned RTU is interrupted. This
