10.3 Transfer of diagnostic alarms to the controller
Note
For "2-pin connection between phase and phase" only the power measured values of the
channels 1, 4 and 6 are relevant.
For "Connection between phase and phase (closed delta)", only the measured values of
channels 1 and 2 are relevant for current and power.
Note
Since the current and voltage values are RMS values, the power cannot be determined by
simple multiplication.
10.3
Transfer of diagnostic alarms to the controller
10.3.1
Transferring diagnostic alarms to the controller: PROFINET
Diagnostics alarms
Diagnostics alarms are transferred as diagnostic interrupts using the channel diagnostics
(identifier 8000h) as the diagnostic type.
The PROFINET device identification number is required for identifying a diagnostic interrupt.
The HCS4300 has the identification number 1002h.
The evaluation in SIMATIC is performed via I/O_FLT1 (OB82) and RALRM (SFB54).
Structure of the diagnostic alarm
Channel diagnosis comprises 6 bytes:

Description
Channel number
The following applies for channel numbers:
Channel number = 0: Diagnostic information relates to one module (CIM, POM, PM)
•
Channel numbers <> 0: Diagnostic information relates to one channel
•
(for POM, PM only)
The channel numbers are counted across the entire HCS.
