1. Ethernet communication (LAN communication Modbus) function
(1) Overview
●
Function for Ethernet communication between the IJ Printer and external unit employing a
LAN environment.
●
Type of Ethernet communication can be selected from Modbus communication.
●
Modbus communication require development of a communication program on the external
unit side.
For the development purpose of communication program, IJP control library will be provided
as a development kit.

Description
1 Modbus
communication
Supports Modbus protocol. Because Modbus protocol is one type of
protocol commonly used by industrial equipment, if Modbus
communication is employed for other unit, you can create a
communications program for the external unit using this asset.
When the communication program is newly developed, its
development schedule will be shortened with use of IJP control
library.
