NCK analog inputs/outputs

1.2.4.1

NCK analog inputs

Amount
General machine data is used to define available analog NCK inputs:
MD10300 $MN_FASTIO_ANA_NUM_INPUTS(Number of analog NCK inputs)
Function
The value of the analog NCK input [n] can be accessed directly in the part program using
system variable $A_INA[n].
The analog value at the hardware input can also be influenced by the PLC user program
(see fig.).
