Hello, I am doing a project that requires the use of recipes, but I am having some difficulties. First I am trying the code with simulations and the thing that is not working is that the value of variables created in PLC is not changing, and HMI gives an error sayng that the connection with PLC is not established. I'm using S7-1200 cpu with KTP 400 HMI. So first I created some PLC tags for the elements of the plc, that I created the HMI tags and connected them with the plc tags, after that I created a recipe and added elements to that which are connected to hmi tags and created data records. I took that recipe and put it in the screen of HMI and after going online with the PLC and with HMI. When I try to put the data of that recipie into PLC I get the error that says that the connection is not established.Any idea what should I do.P.S When I try it with KTP 700 it works just fine!

Sending float value by MODBUS TCP - NB TW01B and S7 1200

Hello, I need to make communication NB TW01B by Omron with Siemens's S7 1200 PLC using MODBUS TCP. I did everything like in this manual: https://www.myomron.com/index.php?action=kb&article=1566 I can read and write single bits from and to DB but I have problem with representation of float variable. In hmi_variable.png you can see my DB. Every BOOL variable communicate just fine the real ones doesnt. In NB - variables.png you can see how i added them into NB panel variable table. Settings.png shows settings of my INPUT number element on the frame( screen in NB). When I write on panel for example number 10.0 then from the panel view it looks properly but in PLC you can see value like in the 10.0.png. What am I doing wrong? Any suggest? hmi_variable.png NB - variables.png Settings.png 10.0.png -
How do I assign an IP address to an S71200 CPU for the first time? Is it possible to do it over ethernet? Thanks in advance!
