3.5.5. SLMP Communication Procedure
An external device and an SLMP-compatible device communicate as follows.
3.5.5.1. Using TCP/IP
The following is the communication procedure when performing SLMP communication with TCP/IP.
With TCP/IP, connections are established when updating, and whether data is received normally or not is checked to
ensure reliability of data. However, the line load is high as compared to UDP/IP.
External device
SLMP-compatible device
The external device issues a connection request
to the robot. (Active open)
Upon establishment of the connection, the external
device sends a request message to the robot.
The external device receives the response message
from the robot and confirms the operation result.
The external device issues a close request
to the robot and closes the communication.
The robot accepts the close request from the
external device and closes the communication.
