10.2 Example of communication with 2MLL-PMEC
This example shows a program that is installed on No. 0 slot of ML200 No. 0 base, sending and
receiving data to Smart I/O module(Station Number 4 and 1) and Extended Smart I/O Pnet(Station
2).

[Table 10.2.1] High-Speed Link Sending/Receiving Map
In the table above, ML200 CPU sends 2 byte data in %MW0 area to MPL-TR2A and 22 byte data
in %MW3000~3010 area to MPL-BSSA and saves 2 byte (16 points) input data of MPL-D22A
in %MW200 area of ML200 CPU and 20 byte input data of MPL-BSSA in %MW3011~3020 area of
ML200 CPU.
10.2.1 N Configurator settings
To exchange data between the systems as in [Figure 10.2.1], it is convenient for the user to
write high-speed link sending/receiving map. In addition, it is necessary to write high-speed link
parameters after setting Network Configuration through N Configurator and download to PLC in
order to send/receive data as in [Table 10.2.1].
