Connected to the output pin Slaves_abHasDiagnostic is a variable of the type ARRAY
[0...127] of BOOL.
In this example, the identifier is SI_diag . This variable is used for all network types, but the
information stored in the variable is nevertheless network-specific:
•
Sl_diag for PROFIBUS (see page 51)
• Sl_diag for DeviceNET (see page 52)
•
Sl_diag for CANopen (see page 51)
5.3.4.1 Sl_diag for PROFIBUS
This variable is an ARRAY [0...127] of BOOL, i.e. a field of 8 words, and contains the diagnostic
bit for each FMU slave.
The bit of the corresponding slave station is logical:
• 1 = latest received slave diagnostic data is available in the internal diagnostic buffer. If
the bit is set to 1, you can enter the corresponding slave station number at the input
Slave_Diagnostic_iNumber , and FPWIN Pro will tell you what the error is.
•
0 = since the last diagnostic buffer read access of the host, no values have changed in
this buffer.
The values in the variable Sl_state are only valid if the master is in the OPERATE state.
