Connecting an external "TEACH" button
You can connect a "TEACH" button to the "TEACH1" and "TEACH2" terminals of the
F-CM AS-i Safety ST module. The "TEACH" button enables the transfer of code sequences
of the connected safe AS-i input slaves. This function is activated by closing the button
contact on the TEACH1 and TEACH2 terminals.
The maximum cable length between the terminal and "TEACH" button is 0.5 m.
Use two wires routed in parallel for connecting the button (not included in the scope of
delivery).
Additional rules and instructions for operating the ET 200SP with fail-safe modules
Observe generally the information in Section "Connecting" in the following documentation:
● Manual ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293/0/en)
● Product Information ET 200SP Distributed I/O System
(http://support.automation.siemens.com/WW/view/en/78361093/0/en)
The conditions for connecting sensors and actuators to the modules of the ET 200SP also
apply generally to the connecting of sensors and actuators to the slaves and modules of the
AS-i network.
In addition, the information in the documentation of the AS-i component applies.
Ensure that all components of the AS-i network are connected in such a way that the voltage
applied to the safety-related AS-i modules is limited to a maximum of 40 V.
The ET 200SP modules CM AS-i Master ST and F-CM AS-i Safety ST have internal safe
electrical isolation from the backplane bus of the ET 200SP.
