• S7 300/400/WinAC CPU (fully supported)
• S7 1200/1500 CPU
• CP (Communication processor - 343/443/IE)

An external equipment can access to S71200/1500 CPU using the S7 'base' protocol, only working as an HMI, i.e. only basic data transfer are allowed.

All other PG operations (control/directory/etc..) must follow the extended protocol, not implemented yet.

Particularly to access a DB in S71500 some additional setting plc-side are needed.

• Only global DBs can be accessed.

• The optimized block access must be turned off.

• The access level must be “full” and the “connection mechanism” must allow GET/PUT.
