WinPC-NC Economy Signal wizzard
Integration of
the signals
WinPC-NC is able to manage a lot of different signals, certainly all
inputs and outputs are not reqired for each task. In this way it is quite
simple to assign the required signals to the available supplies of the
LPT printer port using the signal wizzard.
Each LPT printer port disposes of 5 input lines at the pins 10, 11, 12,
13 and 15 and 4 additional output lines at the pins 1, 14, 16 and 17.
You can connect the required signals at any possible pin. The
assignment is subsequently effected by the signal wizzard which is
activated by parameter-machine-signals.
i
Attention: Please take greatest care when assigning and testing
the inputs and outputs. Be always aware of uncontrolled actions
of the output signals.
Port address
of the interface
Prior to assignment of the individual signals the
LPT port address has to be checked and defined.
Using a second port it is essential to enter also
this address. These addresses are determined by
the operating system and are indicated by the
device manager, as desribed in the preceding
chapter.
6.2. Assignment of inputs
Assignment
of inputs
Please execute the following steps for assigning the input lines:
1. Connect the required switch or sensor to the available pin
2. First click to Signal test and observe the LEDs in the next window
which are symbolizing the status of the individual input lines
3. Note or notice the pin number and the switching logic after
manual pressing the individual switches. A normally open (NO)
contact is characterized when the LED light changes from black to
red during pressing. However, a normally closed (NC) contact is
characterized when the LED light changes from red to black.
