Hello everyone, Can anyone help me if I want to paste the plc data into a web page on a modbus / tcp ip basis then where do I start? I haven't done this before, but I've seen it before.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Basically you add it to your device tree and then set it up. You can Right click on your device in the device tree, add device, add an Ethernet Adapater. Not an EtherNet/IP adapater, that is an ethernet industrial protocol adapater. Then select that new ethernet adapter, your add device window will update, now add either a Modbus TCP Master or a Modbus TCP Slave device.
The Codesys admin's will know better but an OPC UA client/server might be better? I have not personally done anything with OPC UA so I can't tell you much more than what google and the help file can.
OPC UA is designed to be well-suited for connecting the factory floor to the enterprise. Servers can support the transports used in many traditional IT type applications. Servers can connect with these IT applications using SOAP (Simple Object Access Protocol) or HTTP (Hypertext Transfer Protocol).

wago 750-842 type. PLC --> Local web server --> Local computer web browser: data. I don’t want to use webvisu because an html or php provides more options. PLC internal storage is not enough for a more serious web page if I want to use wago's internal web program.

You want to setup the PLC as a modbus tcp/ip slave/master?
You can find the help file for that here.

ahh.. which plc do you want to connect with that?
wago 750-842 type. PLC --> Local web server --> Local computer web browser: data. I don’t want to use webvisu because an html or php provides more options. PLC internal storage is not enough for a more serious web page if I want to use wago's internal web program.
