FC310x as master
FC3101 and FC3102
52
Version: 3.0
Clear-Mode
: It is possible to specify here whether the master enters (or stays in) the "Clear" state as long as
either at least one MC slave (the "Only MC-Slaves" setting) or any slave (the "All Slaves" setting) does not
respond correctly (has a
chapter).
Windows watchdog
: Here a watchdog can be activated, which, in case of a PC crash, will cause the
FC310x to enter the STOP state and terminate the data exchange with all configured slaves (see
). The time is important in
of the primary master.
Set WD individually for each slave:
Here you can select whether the WD should be set individually for
each slave (on the
DP-Watchdog-Time
: If the checkbox "Set WD individually for each slave" is not ticked, the DP watchdog
can be set here to a uniform value for all slaves.
Calculate DP-Slave Watchdog Time
: This is used to set the DP watchdog time for all DP slaves to a
sensible value.

Task-Access-Time (Shift-Time)
: This time must be greater than the maximum TwinCAT jitter plus the
maximum mapping time (see chapter
)
Task access time/task cycle time:
This ratio makes sense if you want to avoid manually adjusting the task
access time when using the
Calculate MC-Times
button.
PLL-Sync-Time
: Only relevant for
Sync-Mode Disabled
, sets the PLL window on the FC310x
Task Cycle Time
: Displays the cycle time of the corresponding highest priority task
Estimated DP-Cycle Time
: Displays the expected PROFIBUS cycle time.
Estimated Mapping Time
: Indicates the expected mapping time.
Set To on Box
: The To-time can be set individually for each slave on the
box
Set Ti on Box
: The Ti-time can be set individually for each slave on the
