Limitations and Recommendations
In order to get the best balancing between functionalities and performances we
strongly suggest to follow some guidelines when designing the applications for
COMBIVIS studio 6 and COMBIVIS studio HMI.
-
The PLC cycle time must be greater or equal than 10ms; the average jitter
has been measured /- 2ms
-
In general the CPU time reserved to CONTROL Runtime shall not be greater
than 25%; this is calculated using the real time required by the PLC
Runtime to complete the cycle and the time left free for all the other pro-
cesses
Note
: The maximum CPU time usable for the COMBIVIS studio 6 application is fixed
from a system parameter; in case the PLC program gets more than 25% of the CPU
time, the CONTROL Runtime will be stopped. The user shall then properly change
the PLC task timing in order to respect the limitation.
-
The maximum number of bytes exchanged between COMBIVIS studio HMI
Runtime and CONTROL Runtime shall not be greater than 1024
-
The sampling time specified for data acquisition shall not be less than
15sec
-
The scripting shall be carefully used in order to leave enough time to the
other tasks to run without impacting too much with the general reaction
of the overall system
-
If the project has been configured to use the Web Client, you should con-
sider that when an external client is connect you may experience a slow-
down of the page change performance of the COMBIVIS studio HMI
Runtime
-
The “S7-MPI COMx” communication protocol from COMBIVIS studio HMI is
not supported.
