Self-Diagnostics; Redundant Power Supply Diagnostics; Diagnostic Interrupts; Hardware Interrupts - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Interface module
11.4 Description of the parameters for the IM 152
If the parameter is disabled and:
● modules are removed and inserted during operation, this leads to a station failure of the
ET 200iSP.
● The actual configuration differs from the preset configuration, no data exchange takes place
between the DP master and the ET 200iSP.
11.4.2

Self-diagnostics

Description
If this parameter is enabled, the diagnostic data for the redundant Power Supply PS are
evaluated.
11.4.3

Redundant power supply diagnostics

Description
This parameter specifies the diagnostic behavior for the redundant Power Supply:
● "No redundant Power Supply": no diagnostics; station failure in event of Power Supply
failure.
● "Redundant Power Supply": Diagnostics for failure of Power Supply PS 1 or PS 2.
This setting is required if you are using two Power Supply units in a redundant configuration.
● "Redundant Power Supply required": Diagnostics and station failure in event of Power
Supply failure.
11.4.4

Diagnostic interrupts

Description
This parameter allows you to enable or disable diagnostic interrupts ("main switch" for the ET
200iSP). Diagnostic interrupts are supported only if the ET 200iSP is in S7 DP or DPV1 mode.
11.4.5

Hardware interrupts

Description
This parameter allows you to enable or disable hardware interrupts ("main switch" for the ET
200iSP). Hardware interrupts are supported only if the ET 200iSP is in S7 DP or DPV1 mode.
