BaseUnit
The BaseUnits provide the electrical and me-
chanical connection of the ET 200SP mod-
ules. Place the I/O modules or the motor
starter onto the BaseUnits.
Suitable BaseUnits are available for each of
the different requirements (see Selecting the
BaseUnit for I/O modules (Page 36)).
Fail-safe power module
The fail-safe power module allows the safety-
related shutdown of digital output modules /
fail-safe digital output modules.
I/O module / fail-safe I/O
module
The I/O module determines the function at the
terminals. The controller detects the current
process state via the connected sensors and
actuators, and triggers the corresponding
reactions. I/O modules are divided into the
following module types:
•
Digital input (DI, F-DI)
•
Digital output (DQ, F-DQ, F-RQ)
•
Analog input (AI)
•
Analog output (AQ)
•
Technology module (TM)
•
Communication module (CM)
