H Status With Profibus (Only For S7-400H And Standard Redundancy) - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Note
Control response
A control behavior is implemented in the electronic modules of the ET 200iSP for parameter
assignment.
If the electronic module receives a faulty parameter, this is rejected. The electronic then
continues to operate with its already valid parameters (the default parameters from the initial
parameter assignment). A "Parameterization error" diagnostic message is not output.
The update interrupt function can be used to check the changed parameters of the electronic
modules. See section "Interrupts in PROFIBUS (Page 212)".
No update interrupt is generated in the case of faulty parameters.

H status with PROFIBUS (only for S7-400H and standard redundancy)

The IM 152-1DP only supplies the H status if it operates on an S7-400H-DP master or is operated
redundantly according to the standard.
The H-status is included as an additional block in the configuration of the device diagnostics,
generally after the manufacturer identification.
