SCHNEIDER STBDAI7220 Channel isolation module

   Link communication mode automatically transfers I/O data (such as relays, coils, and registers) between Machine Controllers. It operates only between STBDAI7220 Modules. Links cannot be used with STBDAI7220 Modules. Machine Controllers send and receive data at regular intervals by a transmission mechanism called token passing according to the link assignment map that has been set in advance. Refer to 9.5.1 Link Communication on page 9-25 for details on link communication. Also, refer to 9.5.4 Token Passing on page 9-32 for details on token passing.

   The MEMOBUS protocol is the standard protocol used up to now for STBDAI7220 communication, and it is the core communication protocols for STBDAI7220 Controllers. The Master sends an MEMOBUS-format instruction to a Slave, and the Slave returns a response message when it has received the instruction.
