control s120 by plc and TB30

dear sir,

i have sinamics s120 controlled by plc s7 1500.i want to control the drive by digital and analog inputs (TB30) as aback up control by the same setting to use it in case of plc failure. how can i configure it in starter 

thank you

Hi, try reading the Commisioning Manual, it´s a good help.

In main program there are 4 words from plc to drive          Control word,speed setpoint,upper torque limit and lower torque limit. 

When I create another CDS I want to send just (on/off ,enable speed set point) from digital inputs and speed reference from analoge input. No extra analoge input for torque.

In another way I will not control the torque in the second CDS

Is this true? 

Thank you for your response

Is this mean that I can change the setting of parameters in expert list in the second CDS

If there is a simple projtec indicats 2 CDS it will be better

Thank you
