HMI Analyzer:
The HMI Analyzer must be started prior to starting HMI-Advanced. This can be done in
service mode. After HMI-Advanced has been booted, the HMI Analyzer displays the actually
existing hotlinks under DDE → Message. Using the "Only Active Hotlinks" option, all active
hotlinks can now be displayed. A check must now be made as to which data accesses will
not need to be implemented as hotlinks but can also be implemented as a request. By doing
this, the basic load on the control can be reduced.
Using the filter request, poke or execute, you can check whether these DDE functions are
burdening the system. Cyclic requests with short cycle times burden the system. The cycle
time can be determined from the "Time" column. This column displays the time that has
elapsed since the start of windows in milliseconds.
Note
OPC DataAccess programmer
When programming an OPC Client Application, the variables to be read are automatically set
up as a hotlink if a variable of the respective group is defined as a hotlink.
In addition, PLC variables for SINUMERIK OPC Server are automatically (Flag
IsActive=True) set up as a hotlink.
