Overview

If a digital output is defined in data record DR 7 for control with data record DR 18 (see
Assignment for digital output 0, 1, 2, 3 (Page 92)), you can control this output with data
record DR 18. Transfer is always for all four digital outputs. Only outputs which are
configured for control by DR 18 (see DR 7 interface parameters (Page 88)) are enabled or
disabled in accordance with the content of data record DR 18.
Procedure
● Check or adapt the desired parameter settings of the digital outputs in data record 7
● Define the value for digital output 0, 1, 2, 3
