Setting of boot−up time/cycle time
Boot−up time (C0356/1) setting
In a CAN network without higher−level control (PLC), a bus node (boot−up master) has to
initialise the CAN network. If the 24 V low−voltage supply is switched on, the boot−up time
elapses. After the boot−up time has elapsed, the NMT telegram for initialising the CAN
network is sent by the boot−up master and the process data transfer is started.
ƒ
Only valid if C0352 = 1 (master).
ƒ
Normally the Lenze setting (3000 ms) is sufficient.
ƒ
State change from "Pre−operational" to "Operational"
Cycle time for process output data (C0356/2...3)
Transmission cycle time for the process data objects CAN2...3_OUT (C0356/2...3) in cyclic
operation (without sync)
ƒ
Setting "0" = event−controlled data transmission
The output data will only be sent if a value in the output object changes.
Activation delay for process output data (C0356/4)
Delay time for initial transmission of the process data objects CAN2...3_OUT after the CAN
bus changed from "Pre−Operational" to "Operational" NMT state.
After the delay time has elapsed, the process data objects CAN2...3_OUT or
CANaux2...3_OUT will be sent for the first time.
