The OP320 are cost-effective HMI (Human-Machine Interface) panel displays that come equipped with an RS232/RS422/RS485 communication port for connecting to various PLCs (Programmable Logic Controllers) using the Modbus protocol 3X and 4X.
The panel display features a monochrome LCD screen and comes with 20 key presses that can be defined to control the PLC functions. The key presses can be configured to monitor and display PLC data and values in real time, making it suitable for use with various PLCs.
The panel display also includes an alarm information list that can be used to display current alarm information by items in real time. This feature is useful for monitoring and diagnosing problems in a PLC system.
Additionally, the OP320 panel displays come equipped with an RTC (real-time clock) function, which can be used to display the current time and date.
Overall, the OP320 panel displays are cost-effective solutions for monitoring and controlling PLC systems using the Modbus protocol, and are suitable for a variety of applications in industrial automation and control.

I am after serial number for software to setup OP20
please check your download file.
I had missed that.,
Good day dear, I want to replace version OP320-A V8.0 , how can I upload the program from the old HMI to the new one I bought
use software you can do.
Hi Just wondering if you could help again.
I have connected the comms and got a program in OP20 Edit Tool
Set the comms up as 9600, 8, none, 1
When I attempt to down load, I get
“Downloading”, and below I get “0%”
but it does not d anything after, just times out.
Message ” Time-Out. Please Check Cable and power. Download again”
but all look ok?
Hi James, I am having the same problem as you. Here is the information I can add that I found.
Serial number: 20210415912
When CTS pin activates, the OP goes into programing mode
After a couple seconds, the OP displays “Downloading 0%”
When I sniff the packets at the serial port, the software sends 0xE8 and 0xF0 to the OP
The OP never replies to this command and the software times out.
I have checked the communication pins after the RS232 SP232E chip with an oscilloscope and the data packets are arriving at the microcontroller but the TXD pins at the micro controller never change state.
I have tried OP20 Edit Tool versions 6.5, 8.0 and 9.4.5
Is the software version you selected correct？
I got it working. I needed to use version v6. I think my problem is that I installed V8 on top of v9 and then installed v6 on top of v8.
I started all over and installed v9, v8 and v6 in separate folders. Then when I tried v6 again it worked first time.
Thank you for your reply! Sorry for the support request. The product is very well built. The boards look very well produced and the soldering looks very good. I am impressed with the quality!

Hello. I have an OR320-A V4.0 panel. I can’t load the project. The panel displays the text Downloaded and that’s it. Software Version 6.5 Y
if lcd is bad?
The download of the project to the operator panel is successful. After downloading, the panel does not open the project, but remains in downloading mode. Probably the system firmware was deleted…
only buy new op320
Does Alarm list is working? I can`t used it, it was empty.

olá comprei uma IHM op320A porém não tem manual, poderia me enviar o manual?? pois preciso muito.
Boa tarde, estou procurando informações também, esse manual da Kalatec, já tem me ajudado muito.
Se conseguires fazer a OP320-A comunicar com o arduino na 485, compartilhe.
I have two OP320-A-S, the COM port and the cable is ok because I can load the program in one of the two displays, the other is blocked in the “connecting..” condition and does not load the program. There is a program in the display that works correctly with the PLC but does not load a new program. Is it possible to reset the display? What can I do ?
Thanks for the reply
connecting..means you need connect a plc
I try to connect OP320A to OMRON PLC but it fail.
