5.7 Subsequent Loading of Drivers (Transmission Protocols)
To extend the functionality of the CP 341 and adapt it to the communication partner, you can
load other transmission protocols onto the CP 341 (loadable drivers) in addition to the
standard protocols in the module firmware (ASCII, 3964(R), RK 512).
The loadable drivers are not shipped with the CP 341 or the parameter assignment interface.
You have to order them separately. (see Catalog ST 70, section "Loadable drivers")
To find out how to install and assign parameters to a loadable driver and load it onto the
CP 341, consult the separate documentation for the loadable driver. Only the requirements
and the fundamentals are described below.
Requirements
The prerequisites for subsequently loading the drivers are:
● STEP 7 V5.3 and higher
● CP 341: Point-to-Point Communication, Parameter Assignment parameter assignment
interface, V5.0 or higher
● The driver dongle must be connected to the port at the rear of CP 341.
● The valid parameter assignment was saved in HW Config beforehand and has been
downloaded to the CPU.
Introduction to the parameter assignment interface
You select the loadable driver for parameter assignment in the CP 341: Point-to-Point
Communication, Parameter Assignment parameter assignment interface.
After you have successfully installed the parameter assignment interface and loadable
drivers, you select the driver you want and assign the protocol-specific parameters in the
same way as you do for the standard protocols. Installation of the parameter assignment
interface and selection of a transmission protocol: see section: "Assigning Parameters to the
Communications Protocols (Page 118)".
To find out what parameters are assigned and how to download the drivers to the CP 341,
consult the separate documentation for the loadable driver.
