5.2 COMBIVIS studio 6 project
This chapter is valid only for C6 HMI LC systems which are coming with CONTROL
Runtime pre-installed directly from production.
5.2.1 C6 HMI LC – Implementation “CONTROL Runtime”
The CONTROL Runtime runs as a thread with “real time” priority.
The execution model is based on the “task” concept; the program execution re-
quires the definition of tasks and the assignment of priority and execution cycle ac-
cording to the following figure (see below in this manual about how to configure
COMBIVIS studio 6 for use with C6 HMI LC system).
Each task is executed at the specified time interval and according to the assigned
priority. 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.
Note : Each task cycle time must be properly assigned according to the general
performances required by the Soft PLC itself, by the COMBIVIS studio 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.
