[RQ9.1] Every time the macro <Set Diag(SD_IDerrOA, permanent)> is executed within the SafetyConsumer, the textual representation shown in Table 29shall be presented. The details and location of this representation (display, logfile, etc.) are vendor specific.

Mandatory

SD_IDerrIgn

The SafetyConsumer has discarded a message due to an incorrect ID.

0x01

A

Yes

SD_IDerrOA

The SafetyConsumer has switched to fail-safe substitute values due to an incorrect ID. Operator acknowledgment is required.

Mismatch of SafetyBaseID

0x11

B, E

Yes

SD_IDerrOA

The SafetyConsumer has switched to fail-safe substitute values due to an incorrect ID. Operator acknowledgment is required.

Mismatch of SafetyProviderID

0x12

B, E

Yes

SD_IDerrOA

The SafetyConsumer has switched to fail-safe substitute values due to an incorrect ID. Operator acknowledgment is required.

Mismatch of safety data structure or identifier.

0x13

B, E

Yes

CRCerrIgn

The SafetyConsumer has discarded a message due to a CRC error (data corruption).

0x04

A

Yes

CRCerrOA

The SafetyConsumer has switched to fail-safe substitute values due to a CRC error (data corruption). Operator acknowledgment is required.

0x14

B, C

Yes

CoIDerrIgn

The SafetyConsumer has discarded a message due to an incorrect ConsumerID.

0x05

A

Yes

CoIDerrOA

The SafetyConsumer has switched to fail-safe substitute values due to an incorrect consumer ID. Operator acknowledgment is required.

0x15

B

Yes

MNRerrIgn

The SafetyConsumer has discarded a message due to an incorrect monitoring number.

0x06

A

Yes

MNRerrOA

The SafetyConsumer has switched to fail-safe substitute values due to an incorrect monitoring number. Operator acknowledgment is required.

0x16

B, C

Yes

CommErrTO

The SafetyConsumer has switched to fail-safe substitute values due to timeout.

0x07

B

Yes

ApplErrTO

The SafetyConsumer has switched to fail-safe substitute values at the request of the safety application.

0x08

D

No

FSV_Requested

The SafetyConsumer has switched to fail-safe substitute values at the request of the SafetyProvider. Operator acknowledgment is required.

0x20

F

Yes.

*) The following classification is specified:A) Transient communication errorB) Permanent communication errorC) Transmission quality seems not to be sufficientD) Application errorE) Parameter errorF) Error does not affect communication itself.

In order to avoid a flood of diagnostic messages in case of transmission errors, only up to two messages are shown even if multiple communication errors occur in sequence. This is ensured by the design of the SafetyConsumer’s state machine.

Optional Feature:Extended diagnostic data by expected value and received value, e.g.Mismatch of safety data ProviderID:Expected ProviderID: 0x00000005Received ProviderID: 0x00000007
