2.7 Parameterization Data
Introduction
By setting the basic parameter, you can define the diagnosis behavior of the CP 340. By
selecting different protocols, you can adjust your CP 340 communications processor to suit
the properties of the communication partner.
The sections that follow describe the basic parameter of the CP 340 and the
parameterization data for the 3964(R) procedure, ASCII driver and printer driver.
2.7.1 Basic parameters of the CP 340
Introduction
You can define in this parameter whether the CP 340 is to generate a diagnostics interrupt
when fatal errors occur.
Basic Parameters
Enter the basic parameter using the STEP 7 dialog "Properties - CP 340". Double-click on
the CP 340 in the STEP 7 configuration table to open the dialog.
Chapter "Parameterizing the Communications Protocols (Page 94)" describes how you enter
the basic parameters of the CP 340
The basic parameters are described in the table below.
