8.3.5 Parameterization of the peer-to-peer functionality
NOTE
8.3-10
The data traffic is determined by the parameterization of the dispatcher
and the transceivers.
The configuration for enabling process data to be sent from a
MASTERDRIVES MC/VC unit is determined by the BICO technique.
The BICO technique is also used to determine the position in the
control system at which the received process data are to act.
Setting is carried out exclusively by means of the parameters of the
MASTERDRIVES MC/VC unit. No additional configuration tool is
required.
Parameterization of the SLB is carried out via the PMU, the OP1S or a
PC with the DriveMonitor start-up tool.
The following parameterizations are necessary for configuring the SLB:
♦ P740: SLB node address
0: simultaneous selection of dispatcher function
1 - 200: simultaneous selection of transceiver function
♦ P741:
SLB telegram failure time (dispatcher and transceiver)
The telegram failure time is a parameterizable failure time which is
stored in every node. The telegram failure time determines the
maximum time between two HW interrupts. The HW interrupt is
generated by the interface after receipt of a SYNC telegram.
If a node does not receive a SYNC telegram within this time (→ no
HW interrupt), the "TlgOFF" diagnostic bit is set in every node in
which the telegram failure time is running.
The telegram failure time is activated after receipt of the first SYNC
telegram.
The telegram failure time should be at least twice as long as the
SIMOLINK cycle time.
If you use the SIMOLINK, telegram failure monitoring should be
activated! P741 = 4 x P746 (SLB bus cycle time) is recommended
for the SLB telegram failure time. See also the function diagram
[140].
