Discrepancy error monitoring
For project engineering with the MLFB 6ES7322-8BH10-0AB0, the SM 322 DO 16 x DC24 V
/ 0.5A offers a discrepancy error monitoring.
The approval of the channel discrepancy error monitoring occurs in channel groups through
the "Discrepancy error" diagnostics settings. With an approved discrepancy error monitoring,
the module constantly checks the set and actual status of the corresponding digital outputs.
With a recognized discrepancy, for example, due to a component defect on the digital
module, the corresponding channel group will be turned off and the "Fuse defect" error will
be reported to all affected channels in the channel group. After removal/insertion or restart of
the module, the digital outputs will be reactivated and the discrepancy test runs again.
A discrepancy error is exclusively reported through the "Fuse defect" error. An additional
indication through the byte 3 "Fuse defect" does not occur. Thus, a differentiation between
the actual fuse blown and a discrepancy error is possible.
Description of the Diagnostic Evaluation

3.24.3 Firmware update via HW Config
Introduction
The SM 322; DO 16 x DC 24V/0.5 A can be updated to the newest firmware version
depending on the available compatible functional updates.
The most recent firmware versions are available from your Siemens representative or from
the Internet (
http://www.siemens.com/automation/service&support
).
Preconditions / Requirements
● STEP 7 V5.5 +(HSP0217) or higher
● With a central use of the module in a S7-300, the firmware update must occur in the
CPU-operating mode STOP. If the CPU is in the operating mode RUN, it may lead to
unexpected behavior and the module is only available after a network off/network on.
● If the module is used in a distributed IO device ET 200M with active backplane bus
modules (removal and insertion allowed), the a firmware update is also possible in the
RUN CPU state.
● With a distributed use without active backplane bus modules, the firmware update is also
possible in the RUN CPU state. Please observe that during the firmware update, the
distributed IO device will be turned off shortly.
