Figure 3-2 Deployment of the driver blocks for output modules
Proceed as follows:
S Determine the module and channel numbers as well as the designation of
the module to which the actuators are connected.
S Select the suitable type of driver for this module (see Table 3–1).
S Define an instance of this driver block (instance DB) and install it in the
OB after the blocks whose values are to be output by the driver to the
I/Os.
S Assign parameters to the inputs of the driver with the required data.
At least the following parameters of the output driver must be adapted
(changing the initial values), in order to effect output to the actuators
connected to the output module:
– BGNR and possibly KNR (depending on the modules plugged into the
rack).
