Only the items that are necessary to read the frequency are given for the execution condition for the
Read NX Unit Object instruction. For details on the variables, using the variables, and the Read NX
Unit Object instruction, refer to the
NJ/NX-series Instructions Reference Manual
(Cat. No. W502).
Allocating the Pulse Rate to a PDO
In this example, you can change the execution condition to TRUE to calculate the data for the pulse
rate value that has been allocated to a device variable. In this example, we will calculate the fre-
quency.
