Operating Modes Of The F-Cm As-I Safety St; Standard Mode - Siemens SIMATIC ET 200SP Manual

Product overview

3.2 Operating modes of the F-CM AS-i Safety ST

Accessories
The following components can be used with the module:
● Labeling strips
● Reference identification label
Ease of maintenance
The following features support maintenance:
● Code sequences are saved in the coding element. As a result, teaching of the code
sequences does not have to be repeated after an F-CM AS-i Safety ST module is
replaced.
● Use is automated to the greatest extent possible. This applies, in particular, to the
teaching of the code sequences of safe AS-i slaves.
● An F-address that has already been assigned is stored in the coding element. This
means that there is no need to repeat teaching-in after replacing the
F-CM AS-i Safety ST module.
● The module/BaseUnit concept allows you to easily replace defective hardware. Remove
the defective module from the rack and plug in the new module.
Further information can be found in the Section "Code sequences (Page 75)".

3.2 Operating modes of the F-CM AS-i Safety ST
3.2.1

Standard mode

Self test during device startup
After the AS-i voltage is switched on (PWR LED shows steady green light), the F-CM AS-i
Safety ST module performs a comprehensive self-test. During this test, all LEDs are lit for
approximately 3 seconds. Exception: the "DIAG" LED is controlled directly by the ET 200SP
backplane bus and indicates the communication status for the ET 200SP system.
Checking of the F-address
After the self-test, the module checks the F-address. If no valid F-address is available, the
"DIAG" and "PROFIsafe" LEDs flash red (the status LED flashes green). You must then
assign the F-address, see Section "F-parameters (Page 44).
