iPar_OK
Name
Meaning
iPar_OK
The bit is set if new parameter values have been assigned to TBPN-
L5-4FDI-4FDX.
Device error
The bit is set by the device for at least two message cycles if there is a
malfunction in the TBPN-L5-4FDI-4FDX.
CE_CRC
The bit is set if the TBPN-L5-4FDI-4FDX detects a communication error
(CRC error). This bit information enables the F-Host to count all faulty
messages within a defined time period and to trigger a configured safe
state of the system if the number exceeds a certain limit (maximum re-
sidual error rate).
WD time-out
The bit is set if the TBPN-L5-4FDI-4FDXdetects an F communication er-
ror, i.e. If the watchdog time in the device is exceeded.
FV activated
This bit is set during a device restart and in case of an communication
error. The outputs of TBPN-L5-4FDI-4FDX are set to the failsafe values.
Toggle_d
Toggle bit in TBPN-L5-4FDI-4FDX that requests a trigger to increment
the virtual serial number within the F-Host (Vconsnr_h) Together with
the control bit "Toggle_h" in the master, the bit serves as an acknow-
ledgment mechanism for monitoring the runtimes between sender
and receiver.
Cons_nr_R
The bit is set if the TBPN-L5-4FDI-4FDX the device has reset its counter
for consecutive numbers (Vconsnr_h).
