9.3.1 Digital inputs
Over
view
A digital input detects a signal coming from outside. The function of a digital input is adjustable.
Description of function
The S200 PTI converter has ten digital inputs, from DI0 to DI9. The S200 Basic PTI converter has
six digital inputs, from DI2 to DI7. A parameter r0722.x is assigned to each digital input. You can
adjust the function of digital inputs by interconnecting the signal parameters to r0722.x in
commissioning tools.
The following signals are assignable to the digital inputs.
