13.4 Digital inputs / outputs
13.4.1 Digital inputs
The number of digital inputs is different from a position controller to another. Here is a table giving the number
of digital inputs present on each position controller (refer to the corresponding ’Hardware Manual’ for more
information):
Caution: On the DSCDM, the digital inputs and outputs are on the same pin. The pin must be selected in
order to have an input or an output. It is NOT possible to have both on the same pin. To
use a pin as a digital input, the bit corresponding to this input MUST be equal to 0 in parameter
K171 (otherwise the hardware of the controller and the one of the user can be damaged).
13.4.1.1 Digital inputs on position controller
The DIN command enables the reading of the digital inputs states. This command is an alias of monitoring M50.
A bit equal to 1 means that the corresponding digital input is activated and equal to 0 means that the
corresponding digital input is deactivated. The digital inputs bits values are as follows:
Example:
A simple conversion in binary of the value shown by DIN (in hexadecimal) is enough to know which digital
inputs are activated and deactivated.
In the first line of the above-mentioned example, DIN1 and DIN2 are activated.
DIN.1 ;Reads the digital inputs state. The controller gives the value 3 in hexa, because 0x3 in binary is
0000000011 and each bit represents one of the digital inputs, from right to left.
In the second line of the above-mentioned example DIN1, DIN9 and DIN10 are activated.
DIN.1 ;Reads the digital inputs state. The controller gives the value 301 in hexa, because 0x301 in binary
is 1100000001 and each bit represents one of the digital inputs, from right to left.
