Structure of DP slave diagnostic data

The Function Block DPM_SLV_DIAG divides the diagnostic data of a DP slave into sections and applies them to the corresponding outputs. The structure of the DP slave diagnostic data is prescribed by the standard as follows:

Octet 1	Stationstatus_1 DPM_SLV_DIAG	STAT_1
Octet 2	Stationstatus_2 DPM_SLV_DIAG	STAT_2
Octet 3	Stationstatus_3 DPM_SLV_DIAG	STAT_3
Octet 4	Master_Add DPM_SLV_DIAG	MSTR
Octet 5 to 6	Ident_Number DPM_SLV_DIAG
Octet 7 to 244	Ext_Diag_Data DPM_SLV_DIAG	EXT_DIAG_DAT[1] to EXT_DIAG_DAT[EXT_DIAG_LEN]

• Stationstatus_1; STATIONSTATUS_1_TYPE
• Stationstatus_2; STATIONSTATUS_2_TYPE
• Stationstatus_3; STATIONSTATUS_3_TYPE
• Master_Add, MSTR; BYTE
• Ident_Number
• Ext_Diag_Data; EXT_DIAG_DAT   ARRAY \ [1..238] OF BYTE
