PROFIBUS address
All bus nodes must be assigned a unique PROFIBUS address for their
identification on the PROFIBUS network. Available PROFIBUS addresses for
ET 200eco: 1 to 99.
PUR sheath
Cable with polyurethane (PUR) sheath (protective sheath).
Reference potential
Arbitrary electrical point of reference (zero potential) for the measurement and/or
monitoring of voltages in circuits referenced to this potential.
Slave
A slave may only exchange data with a
master on request. Slaves are, for
example, all DP slaves such as ET 200S, ET 200X, ET 200M, ET 200eco etc.

PROFIBUS address
T functionality
This functionality is integrated in all terminal blocks by default. Refers to the
through–loop of PROFIBUS DP and of the power bus to the next PROFIBUS
node. Result: When you disconnect the terminal block during runtime, the
downstream PROFIBUS nodes can continue operation.
Terminal block
Plug–in module for quick change of the terminal configuration. Available
versions: ECOFAST and M12 / 7/8”.
Voltage designations for ECOFAST
Alternative voltage designations for ECOFAST:
•
Electronic/sensor power supply (1L+) = load voltage, not switched (NS)
•
Load voltage supply (2L+) = load voltage, switched (S)
