The following table shows the relationship between the SI_state bit and the SI_diag bit.
SI_state = 0 SI_state = 1
Sl_diag = 0 •
No data I/O exchange between master
and slave.
Perhaps this slave is not configured or not
responsive.
•
Slave is present on the bus.
•
Data I/O exchange between master and
slave.
Sl_diag = 1
• The master and the corresponding slave
are not exchanging I/O data.
•
The master holds newly received
diagnostic data in the internal diagnostic
buffer.
• Slave is present on the bus.
•
The master and the corresponding slave
are exchanging I/O data.
•
The master holds newly received
diagnostic data in the internal diagnostic
buffer.
5.3.4.2 Sl_diag for DeviceNet
This variable is an ARRAY [0...127] of BOOL, i.e. a field of 8 words, and contains the diagnostic
bit of each device. For DeviceNet, bits 0 to 63 are available.
The of the corresponding device is logical:
•
1 = newly received diagnostic values are available in the internal diagnostic buffer or
one of the diagnostics bit of the device has changed. 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
the internal diagnostic buffer.
The values in the variable Sl_state are only valid if the master is in the OPERATE state.
The following table shows the relationship between the SI_state bit and the SI_diag bit.
SI_state = 0 SI_state = 1
Sl_diag = 0 •
Device not operative, no process data
exchange between FMU and device.
•
Device is not configured.
•
Device is present on the network, device
guarding active.
•
Process data exchange between FMU
and device happening as configured.
Sl_diag = 1
• Device is not operating, device guarding
failed or configuration fault detected.
•
New diagnostic data provided by the FMU
in the internal diagnostic buffer to be read
by host.
• Device is present on the bus, device
guarging is active, process data
exchange.
• New diagnostic data provided by the
FMU in the internal diagnostic buffer to
be read by host.
5.3.4.3 Sl_diag for CANopen
This variable is an ARRAY [0...127] of BOOL, i.e. a field of 8 words, and contains the diagnostic
bit of each node. The bit of the corresponding node is logical:
•
1 = newly received emergency message are available in the internal diagnostic buffer or
one of the diagnostics bit of the node has changed. If the bit is set to 1, you can enter the
corresponding node number at the input
Slave_Diagnostic_iNumber , and FPWIN Pro
