Display of the connection resources for HMI
For information regarding the availability and assignment of connection resources for HMI
connections, refer to the "Connection resources" properties in the Inspector window of the
offline view (in the context of the HMI device).
Figure 12-6 Connection resources - HMI communication
The following is displayed in the connection resources area:
•
Number of available connections on the HMI reserved for HMI communication and HTTP
communication
•
Number of connection resources for HMI communication and HTTP communications used
offline in the HMI
If the maximum number of available connection resources for an HMI device is exceeded,
a corresponding message is output by STEP 7.
•
"Maximum number of used PLC resources per HMI connection". This parameter is a factor
that is to be multiplied by the number of HMI connections used offline. The product is the
number of HMI resources occupied on the CPU.
Displaying the connection resources in the Web server
You can display the connection resources not only in STEP 7, but also with a browser that
displays the relevant page of the Web server.
You will find information on displaying connection resources in the Web server in the Web
