The FB instances for all F-Devices are automatically generated and can be found in CODESYS
Safety project in "Resources è Global Variables è PROFIsafe" (Fig. 87 on page 191). These
FB instances, as normal global variables, can be accessed by end-users from their safety appli-
cation programs.

DANGER!
To avoid unintended behavior, e.g., unintended restart, of 3rd party PROFIsafe
devices, one shall pay a special attention to the description of PROFIsafe
Device_Fault bit in the safety user manual for those devices.
It is highly recommended to continuously supervise Device_Fault bit of 3rd party
PROFIsafe actuator devices like valves, etc. to avoid unintended restart of
those after, e.g. power failure. If Device_Fault = 1 is detected for such devices,
then the safety application shall passivate the module with activate_FV_C = 1.
The permission for restart (activate_FV_C = 0) shall be handled in the safety
application using the functionality similar to that of FB SF_OutControl
Ä Chapter 4.6.4.17 "SF_OutControl" on page 282.

Description, parameter values
This parameter is for debugging purposes only.
This parameter is set to TRUE if communication fault
(timeout on F-Host side) occurred.
This parameter is for debugging purposes only.
It represents the current response time for F-Device
in ms. This value shall be smaller than the defined
F_WD_Time parameter for the given F-Device. If not,
then the passivation of the given F-Device will
happen.
