Laser Welding by External
Communication Control
(RS-485 CONTROL)
1. Operation Flow
This section explains an operation flow of a laser welding by external
communication control (RS-485 CONTROL).
The following methods for laser welding operations are available: control from the
laser controller (PANEL CONTROL), control by external input/output signals from
the PLC (Programmable Logic Controller) connected to the connector (EXTERNAL
CONTROL), and control by sending a command from the connected personal
computer (RS-485 CONTROL).
At the control by external communication (RS-485 CONTROL), the original customer-
developed program is executed on the personal computer to set laser output
schedules and read monitor data and various types of status.
* PLC: Programmable Logic Controller This unit exerts sequence control by executing the
programmed contents of control in sequence. This is often called Sequencer (product name of
Mitsubishi Electric Corporation).
