ChannelDiagnosisData (STRUCT)¶

TYPE ChannelDiagnosisData : STRUCT

Diagnosis information in standard format.

There are ranges of ErrorTypes that are defined by the Profinet Standard, see enum ChannelErrorType.
Manufacturers can define device specific errors in the GSDML of their Profinet Device.
The ChannelErrorType and the ExtChannelErrorType match the ErrorType of the ChannelDiagItem- and ExtChannelDiagItem- elements of the GSDML.

Example

<ChannelDiagList>
    <!-- Only use manufacturer specific range for ChannelErrorType = 0x0100 – 0x7FFF ! -->
    <ChannelDiagItem ErrorType="4096">
        <Name TextId="DIAG.Runtime-Cfg"/>
        <ExtChannelDiagList>
            <ExtChannelDiagItem ErrorType="1">
                <Name TextId="DIAG.IP-Change not allowed"/>
                <Help TextId="DIAG.IP-Change not allowed.Help" />
            </ExtChannelDiagItem>
            <ExtChannelDiagItem ErrorType="2">
                <Name TextId="DIAG.DynamicIP"/>
                <Help TextId="DIAG.DynamicIP.Help" />
            </ExtChannelDiagItem>
        </ExtChannelDiagList>
    </ChannelDiagItem>
