In the operating mode PROFIBUS DP SyncIn the CPU cycle is synchronized to the cycle
of the Yaskawa PROFIBUS DP master system. Here the CPU cycle depends on the
Yaskawa DP master with the longest cycle time. If the CPU gets into RUN it is synchron-
ized with each PROFIBUS DP master. As soon as the CPU cycle is passed, it waits for
the next synchronization impulse with input data of the DP master system. If necessary
the Scan Cycle Monitoring Time of the CPU should be increased.
By presetting the PROFIBUS bus parameters within the hardware configuration a token
time for the PROFIBUS results. The token time defines the duration until the token rea-
ches the DP master again. Per default this time is supervised. Due to this monitoring dis-
turbances on the bus can affect a reboot of the DP master. Here with the parameter
Token Watch the monitoring of the token time can be switched off respectively on.
Default: On
Here the number of flag bytes may be set. With 0 the value Retentive memory > Number
of memory bytes starting with MB0 set at the parameters of the Siemens CPU is used.
Otherwise the adjusted value (1 ... 8192) is used. Default: 0
The priority fixes the order of interrupts of the corresponding interrupt OB. Here the fol-
lowing priorities are supported: 0 (Interrupt-OB is deactivated), 2, 3, 4, 9, 12, 16, 24.
Default: 24
Once during a cyclic interrupt OB (OB 28, 29, 32 ... 35) the same cyclic interrupt is
requested, the interrupt requests are collected and processed sequentially. Via the
parameter 'OB 80 for cyclic interrupt' you can set here for the corresponding cyclic inter-
rupt group that on a cyclic interrupt instead of the sequential processing the OB 80 is to
be called. With this parameter you have the following settings:
n Deactivated (default)
– At a cyclic interrupt error the interrupt requests are collected and processed
sequentially.
for OB...
n
– At a cyclic interrupt error of the corresponding cyclic interrupt OB, the OB 80 is
called.
