Glossary
Aggregate current
The sum of the currents of all the output channels of a digital output module.
AUX1 bus
Power modules permit you to connect additional potential (up to 230 VAC), which you can
apply by means of the AUX(iliary) bus. You can set the AUX(iliary) bus individually:
•
As a protective conductor bar
•
Additionally required voltage
Backplane bus
The backplane bus is a serial data bus via which the IM151-1 interface communicates with
the electronic modules/motor starters, supplying them with the required voltage. The
connection between the individual modules is established by means of the terminal modules.
Bus
A common transfer route connecting all notes and having two defined ends.
In the case of the ET 200, the bus is a two-wire or fiber-optic cable.
Bus connector
A physical connection between the bus nodes and the bus line.
Chassis ground
Chassis ground refers to all the interconnected inactive parts of a piece of equipment that,
even in the event of a fault, cannot carry voltage that is dangerous to the touch.
Configuration
The systematic arrangement of the different ET 200S modules (setup).
Connecting to common potential
The opening of a new potential group by a power module. This permits the individual
grouping of the sensor and load supplies.
