between a pc and a siemens s7. it's not hard to get it running, but it's getting hard to make it faster than 100millisecs per packet. the only way out seems to be a dll shipped by siemens. but all those functions need pointer like HWND - types. what to do?I have no experience with your Siemans s7 but i have used industrial
ethernet I/O and refreshed it sub 50mS rates . I used TCP/IP modules but
re-used the same refnum without closing the TCP/IP session. If you are not
already doing that, I hope it helps .

hi, i do have to set up a industrial ethernet connectíon between a pc
and a siemens s7. it's not hard to get it running, but it's getting
hard to make it faster than 100millisecs per packet. the only way out
seems to be a dll shipped by siemens. but all those functions need
pointer like HWND - types. what to do?
cheers mario gansen
it is not possible to use the siemens opc - server, because it doesn't
allow update rate
s smaller than 100 msecs.
