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

Commissioning and Diagnostics
6.8 Diagnostics with STEP 7
Note
Control response
A control response is implemented for assigning parameters in the electronic modules of the
ET 200iSP.
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). No "parameter error" diagnostic messsage is output.
The update interrupt function can be used to check the changed parameters of the electronic
module. See section "Interrupts (Page 171)".
No update interrupt is generated in the case of faulty parameters.

H-Status (only with the S7-400H and standard redundancy)

H-status
The IM 152 supplies the H-status only if it is running on an S7-400H DP master or is operated
redundantly according to the standard.
In the structure of the slave diagnostics, the H-status is represented by an additional block,
typically following the manufacturer's ID.
