Communications using the SLMP

This type of the data communication is used to read/write data of the master station and the remote station from the external
device, such as a personal computer or HMI (Human Machine Interface), via an SLMP.
The Motion module sends and receives SLMP messages. For details on SLMP, refer to the following.

For SLMP communications, set the same communication speed for the connected station and access destination. If the
communication speed differs between the connected station and access destination, SLMP communications may not be
performed.
