What do you mean by "the protocol about iso_on_tcp?"
Iso on tcp means a complete ISO packet is transported as the payload of a TCP packet. This is specified in RFC1006.
In case of S7 the payload in the ISO packets is S7 communication and there is no specification for it publicly available.

A good reference for the ISO8073 protocol can be found <a href="http://www.synapse.de/ban/HTML/P_ISO/Eng/P_iso66.html"> http://www.synapse.de/ban/HTML/P_ISO/Eng/P_iso66.html</a>.
The 3 "useful" headers are:
CR - Connection request
CC - Connection response
DT - Data exchange
