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.
List of functions
No. Function name 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.

(3) Notice
● The time from when the signal is transmitted from an external unit to when the IJ Printer
receives the signal cannot be strictly defined in the same way as with serial communications.
