Table 4- 10 Changing the function of a digital input
Changing the function
Examples
1. Select the required function marked using a "BI" parameter.
2. Set this parameter to the value of the status parameter r0722.x of the
required digital input.
Function : Switch on motor via DI 2.
Setting : p0840 = 722.2
Function : Acknowledge fault using DI 1.
Setting : p3981 = 722.1
