5.4.1 Introduction
Introduction
You can set the response of the CP 440 to CPU STOP by means of the basic parameters. By
selecting di󹪜erent protocols, you can adjust your CP 440 communication processor to suit the
properties of the communication partner.
The sections that follow describe the basic parameters of the CP 440 and the con󹪝guration data
for the ASCII driver and for the 3964(R) procedure.
5.4.2 Basic Parameters of the CP 440
Basic parameters
Enter the basic parameters in the STEP 7 HW dialog box "Properties - CP 440 ". Open the dialog
box by double-clicking the CP 440 in the con󹪝guration table of STEP 7.
