Hello!
I need help with automation modernization project. Old automation process control system uses Siemens Simatic S 115U CPU 943, that is ok.
But do you have any infomation of Siemens WF-470 video display system? Its about 15 years old. How WF-470 and CPU 115U conversates together?
How this old model WF-470 video processor sends and gets data from S5 CPU
115 Data Block and Data Words?
