Hello everyone. I am new on this comunity and i have ine question. I have a s7-300plc and an op3 panel. The op3 panel was broken and i buy other one. I reset to default program and i dont know how to make the project to be same like the old one. Please help because i am on the ccontainer ship and really we need to fix this. Thanks in advance

Look here for the manual
https://support.industry.siemens.com/cs ... nload=true

it will show how to set comms and load configuration

[Claudiu1987]

I already read the manual but this showing how to make a new project. So i have download with step7 the config from plc and i dont know how to make a project for op3 from plc database.

Please check section 14 "Commisioning" in the manual.
This shows you require Protool to load the config.
Have you the original Protool project?

[Claudiu1987]

This is the problem that i don t have the original project. I have only the plc with the project and a new op3 panel. I dont know how to create a project for op3 to display and operate the s7 plc. I have step7 and protool and a mpi interface. I manage to copy database from plc s7 to step7 and i dont know the next steps. I am novice in this domain.

Without the original project it will be difficult.
You must find the variables in the PLC that you wish to display on screen.
This could be BIT, BYTE, WORD, DWORD in the Marker or Data block area.
The same applies if you want to change setpoints etc.

In protool you build the screens and incorporate these Marker or Data Block address that you wish to see/change.

Can you contact the supplier to see if they have the project?

[Claudiu1987]

The supplier no more existing. This is a air condition controller. I need to change setpoint and to monitor the temperature. I manage to download the plc database with step7 but now i dont know how to make the project for op3.one video to take a example where i can get? Tnk you very much in advance.
