Communication partners
All HTTP clients (e.g., Web browsers) represent potential communication partners
of the HTTP server. The HTTP server of the CP 243-1 IT supports simultaneous
access of up to 4 Web browsers.
The TCP/IP connection to the HTTP server is always handled by port 80.
Performance/general conditions
On the CP 243-1 IT, HTTP communication is subordinate to S7 communication.
Reaction times vary with the particular configuration and cannot be predicted gen-
erally in advance.
The HTTP server located on the CP 243-1 IT has four communication channels
(i.e., it can process up to four requests at the same time). When a request arrives
at the HTTP server when all four communication channels are occupied, the re-
quest is rejected. New requests cannot be processed until at least one of the four
communication channels is free again.
