Figure 24: Task Configuration For Ethercat Master Task - KEB COMBICONTROL C6 SMART Instructions For Use Manual

COMMISSIONING A PROjeCT
Figure 24:
Each task is executed at the specified time interval and according to the assigned prior-
ity. Only when all the COMBIVIS studio 6 activities are over, the CPU time goes to the
other processes, as they are assigned to an inferior priority.
Task configuration for EtherCAT master task
The task configuration for the EtherCAT master task must be set to type =
"External" and External event = "EVENT_ECM_DC"!
Each task cycle time must be properly assigned according to the general
performances required by the BASIC / PRO / ADVANCED itself, by the HMI
runtime, by the COMBIVIS connect runtime and by any other application or
process running in the system. A too short task cycle time may introduce an
undesired slowdown in the general reaction of the system. If this is the case,
the task cycle time should be properly increased until you reach the proper
balancing between performances and reactivity of the whole system.
To avoid cycletime overflows the KEB gateway must not run in the EtherCAT
task!
Trace is not running properly on EtherCAT external task, if task load is higher
than 50%! Then there are gaps in measurement expected!
