Transient transmission
The transient transmission is a function that communicates data only when there is a communication request. Data
communication is performed between stations by using SLMP and other protocols, regardless of the communication cycles.
For CC-Link IE TSN, transient transmission and cyclic transmission are performed using different communication bands in
order to ensure the stability of the cyclic transmission.
Transient transmission in the motion mode
With SLMP, actions such as reading the servo amplifier model code and accessing each object can be performed. For reading
and writing each object, the SDO Download command, SDO Upload command, and other commands are used.

SLMP command
The following is a list of SLMP commands.
Drive profile
This section explains the CiA 402 drive profile specification as well as the unique functions of servo amplifiers. Each function
can be controlled by using the object dictionary via the network.
A list of drive profile specifications is as follows.
