Transient Transmission
This function communicates with other stations during execution of MELSEC data link functions.
Transient transmission applies to communication of low-frequency reading and writing data and large-sized data.
Communication within the same network
Transient transmission to other stations is performed by MELSEC data link functions.
Access to devices on another station
Devices of other stations are accessed directly by a user program.
Connected network modules and control CPU modules can be accessed.
