Plan: connecting the system blocks "Inputs_Digital" and "Outputs_Digital"
If you want to use digital input 1 and digital output 1, carry out the following steps:
1. Explicitly integrate the system blocks Inputs_DIGITAL and Outputs_DIGITAL into the
control configuration of the DDS. (
¶ 26)
2. For access to digital input 1:
– Assign the system variable DIGIN_bIn1_b to a POU variable.
3. For access to digital output 1:
– Assign the system variable DIGOUT_bOut1_b to a POU variable.
)
Note!
According to the IEC 61131−3 standard the system variables DIGIN_bIn1_b and
DIGOUT_bOut1_b may generally only be used once.
The use of one system variable in several POUs must be carried out via a copy
(as global variable).
