Caution
Product Description
Mitsubishi high-precision sequencer with selections to best suit the system and the target devices.
[Features]
· Supports 100BASE-TX for high-speed transmission (QJ71E71-100).
· Capable of transmitting and receiving data between the sequencer CPUs using the dedicated commands.
· Can connect with multiple programming tools for increased debugging efficiency.
· Text body (in ASCII format) and attachment files (in binary/ASCII/CSV format) can be sent via email.
[Applications]
· Convenient for connections with field networks.
This Product's Features
Example of connection
- Sequencer devices can be accessed from the web browser on a PC via the HTTP protocol. You can obtain a communication library and sample screens that work on a PC (web) from a download service.
- Alive check of the other device using the KeepAlive function (alive check function) lets you detect if the connection has closed due to a malfunction of the other device.
Immediate Communication By Only Selecting Desired Device From Communication Protocol Library
1. Select the manufacturer and model number (series) of the connecting device
No need to set a complex communication protocol with the connecting device. All you need is to select from the provided communication protocol library, such as the MODBUS, BACnet, etc.
2. Write a communication protocol to the unit
Write a pre-defined communication protocol to the QJ71E71-100 or QJ71C24N(-R2/R4) unit.
3. Execute the protocol from the ladder program
The ladder program only needs to execute a dedicated communication protocol start command, to initiate communication with the external device
Easy to Create and Edit Communication Protocols
Even when a desired device is not found in the communication protocol library, an additional communication protocol can be created in easy steps.
You can view the content of the created communication protocol for easy editing.
- *Supported by QJ71C24N(-R2/R4) of Function Version B or later, whose serial number starts with "11062."
- *Supported by QJ71E71-100 whose serial number starts with "15042" or later.
