Function description


The H7-200Smart series Ethernet interface module transmits the IO data of the IO module extended after 

the interface module to the master station through the S7 slave station protocol.

It has the following characteristics:A maximum of six smart expansion modules can be expanded Support 

S7, access to zone I, Q, AI, AQ and V; Available via S7 protocol (as slave)

Convenient and efficient S7 communication with the S7-200SMART or H7-smart series CPU

Support module type

All digital value and analog value expansion modules are supported 

(including I/O modules that use the V zone), DP01 is not supported.
