Evaluating Interrupts Of The Et 200Isp By The Cpu With Profibus - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Commissioning and Diagnostics
7.13 Diagnostics with STEP 7 with PROFIBUS
• After a diagnostic message this is
– entered in the diagnostic frame as diagnostic interrupt block (always only one interrupt)
– stored in the diagnostic buffer of the CPU
– entered in the channel related diagnostics
• The SF LED lights up on the IM 152-1DP interface module.
• The OB82 is called. If there is no OB82, the CPU goes to STOP operating state.
• Acknowledgment of the diagnostic interrupt (after which new interrupt is possible)
Actions after a diagnostic message in DPV0 mode
The error is entered in the diagnostic frame in the channel-related diagnostics:
• The SF LED lights up on the IM 152-1DP interface module.
• There can be more than one diagnostic message at the same time.
Causes of Error and Troubleshooting
The causes of errors and remedial measures of the diagnostic messages are described in the
section "Channel-related diagnostics with PROFIBUS (Page 207)".
7.13.4

Evaluating interrupts of the ET 200iSP by the CPU with PROFIBUS

Introduction
The interface module triggers interrupts for specific errors. The interrupt evaluation varies
depending on the CPU used.
Evaluate interrupts using the CPU
Requirements: You have configured the ET 200iSP with the engineering tool STEP 7; i.e.
interrupts are only supported if you integrate the ET 200iSP as follows:
• IO device
• S7 DP device
• DPV1 device
In case of an interrupt, interrupt OBs run automatically in the CPU (see programming manual
System software for S7-300/S7-400, program draft
support.automation.siemens.com/WW/view/en/1136533)).
Evaluate interrupts at PROFIBUS with other DP master
If you operate the ET 200iSP with another DP master or as DP standard device, then no interrupts
are generated.
