SAFECONF Online configuration with PLCnext Modbus TCP
Hello,
I'm trying to connect PLCnext to Safety logic(LPSDO) via Modbus TCP for online configuration.
I got modbus TCP library (https://www.plcnextstore.com/#/246) from plcnext store and implemented like example server described in the document.
I could connect PLCnext to Modbus TCP client via port 502(for test) but couldn't connect with SAFECONF.
The attached setting parameters are required according to the quick start guide of SAFECONF.
I didn't know how to set the last parameter, "Value Register" to the Modbus library.
Could you tell me the way?

Hello Atsushi,
you do not need the modbus TCP library for this. You can find everything in the Safety Bridge libary. When I see your attached image, your connection is between Safeconf and the PLC.
Have you already uploaded a project to the LSPDO and is it already running?
Greetings Jörn
Hello Jörn-san,
Thank you for the answer.
NO, the picture is just copy of the manual(for your referece). Sorry to confuse you.
Yes, I've already uploaded Safeconfig binary file to the PLCnext and it works.
Next, I would like to online HostPC via ModbusTCP for debugging.
Do you mean the SB library has Modbus TCP functionality?
If so, could you tell me how the value register to the STB library?
Best regards,
Atsushi
Unfortunately I cannot tell you exactly how I am doing in the SBT library.
However, I have attached a sample project to you once. In this project you can see the wiring of the blocks.
Please delete ".pdf" at the end of the file.
