Diagnosis Suppression

Description

Diagnosis suppression is used to suppress diagnosis messages from the device. There are two possibilities here:

Diagnosis suppression level that permits a general suppression of messages of a certain level (message, warning, error).
Event-code suppression of up to 5 events as a list or via a teach-in.

ISDU

Diagnosis suppression – ISDU
Name	Index	Subindex	Access	Length	Data Type	Data Storage	Default
Diagnosis Level Configuration	0x0070 (112)	0	R/W	1 byte	UINT8(ENUM)	Yes	0
Event Code Suppression	0x0071 (113)	0	R/W	10 bytes		Yes
Event Code Suppression		1…5	R/W	2 bytes	UINT16	No	0
Event Code Suppression Teach-in	0x0072 (114)	0	W	2 bytes	UINT16	n/a	–
Event Code Suppression Delete	0x0073 (115)	0	W	2 bytes	UINT16	n/a	–

Diagnosis Level Configuration Parameter

This parameter offers the possibility to select an output level for events.

This index is part of the data management and is stored in non-volatile memory.

Diagnosis suppression – Diagnosis level configuration
Value	Diagnosis Level	Descriptions
0	All events	All diagnosis messages are reported (default setting).
1	Warnings and errors	All warnings and errors are reported – messages are suppressed.
2	Error	Only events of type error are reported.
3	No events	All diagnosis messages from the device are suppressed.

Events

For an event overview, see Events.

Event Code Suppression Parameter

This parameter indicates the currently suppressed event messages. The user can access the individual messages via subindex 0 or a specific subindex. This index is part of the data storage and is stored in non-volatile memory.

Value 0x0000 (0) is the default value and is interpreted as FREE.

Each event message is structured as follows:

Diagnosis suppression – Event Message Suppression
Byte1 (MSB)	Byte0 (LSB)
Event Code High Byte	Event Code Low Byte

Event Code Suppression Teach-in/Delete

To add an event to the list of suppressed events, the event code is inserted in subindex 0 in Event Code Suppression Teach-In. It is added to the next free place in the table.

If the event code is deleted with Event Code Suppression Delete, it is removed from the list.
