[?]: Dupline analog and Digital Mapping to S7-200 and s7-300

[reymond_craig]

Dear Sirs,

Good evening, I currently have project and the client want to use dupline to communicate to plc.
The PLC needs to read analog and digital data from dupline and right Digital data to dupline.
I want to propose siemens PLC as I'am comfortable with siemens on my projects.
The problem is I can't find documentation for data mapping of Analog and digital IO from dupline to Siemens PLC and Vice versa.
I only found mapping for digital IO only on s7-200. Thanks for any help
