3.24 Digital output module SM 322; DO 16 x DC 24 V/0.5 A: (6ES7322-8BH10-0AB0)
All identification data (I&M) is stored retentively in a module and supports you with the
following tasks:
● Error search and repair in the system
● Testing the system configuration
● Finding changes to the system hardware.
The SM 322; DO 16 x DC 24V/0.5 A supports:
● I&M 0 (identification)
● I&M 1 (system identification / location identification)
● I&M 2 (installation date)
● I&M 3 ( additional information)
Reading and writing the identification data with STEP 7
System-dependent information (M-data) is configured in the properties dialog of the module.
You obtain information on the module (I data) from the module status dialog. The system-
dependent information on the module is displayed here too.
Note
Identification data can only be written for modules if the CPU is in the STOP operating mode.
Reading and writing the identification data with PDM
Through the "Identification" flap, the identification data is evaluated and transferred to the
module. Location identification is not available in PDM.
Note
Identification data can only be written for modules if the CPU is in the STOP operating mode.
It is recommended to change at most one entry per download, if applicable, the transferring
of the identification data must be activated multiple times.
