Fieldbus Watchdog; Support Of Dsp402 Profile - KEB COMBICOM Instruction Manual

Powerlink Operator
The Powerlink operator (at HS_SyncToutMode !=0) changes into automatic synchronous mode if the synchro-
nous mode is activated, but no SoC interrupts are received. This is displayed in the operator display:
Thus the operator simulates itself the SoC interrupts time controlled in the adjusted Synch cycle time. The time-
out-time when changing into automatic synchronous mode is in standard 4 * SYNC cycle time (Com Cycle).
The operator switches only into synchronous-mode , if
• Processdata-mapping in both direction follows the structure 1*32-Bit + 1-2*16-Bit is.
• Bit "EnableSyncMode" is activated in operator parameter "FBS Config".

3.2.3 Fieldbus watchdog

The field bus watchdog is a monitoring function of the Powerlink operator. The field bus watchdog serves to place
the FI control into error status (E.BUS or A.BUS) if special communication events do not appear cyclically. Two
operator parameters (Watchdog inhibit, Watchdog activation) configure the watchdog at operator side. Further-
more parameters Pn.05, Pn.06 must be set in the FUI control in order to define the timeout-time and the reaction
to carry out in a timeout-case.
The Powerlink operator monitores the occurrence of the configurated field bus events (Watchdog inhibit). These
events reset the watchdog-timer. Several fieldbus events can be defined as reset-event. The operator instructs
the FI control via a special command if the watchdog time counts down without at least one of the configurated
field bus events. The FI control reaction is determined by parameters Pn.05, Pn.06 (already mentioned). The co-
ding of these two parameters can be taken from [3].
3.2.4 Support of DSP402 profile
The KEB-F5-Powerlink operator supports some elementary objects of the DSP402 profile. This parameters are
defined in [4]. Only the velocity mode is integrated. A list of these parameters can be found in the annexe.
