AUMA Aumatic AC 01.1 Short Instructions

5.2 Assignment of the customer inputs of the Profibus DP interface (option)
X4 This plug provides pins for 4 digital customer inputs and 2 analogue
customer inputs.
These signals are freely available inputs, which the microcontroller transmits
into the process representation input (OPTIONS part 1, bits 4-7). The inputs
are galvanically isolated and internally connected to 0 V via pull-down resis-
tors. In an unconnected state a logical zero is transmitted. To set an input to
logical one, + 24 V DC must be applied.
Via these inputs external 0/4 – 20mA sensors for transmitting the measured
values through the Profibus can be connected.
.
Proposed wiring diagrams (appendix C of the operation
instructions) for these signals must be observed.
.
The bounce time of the connected switches should not be
more than 1 ms.
.
The inputs AN1 and AN2 do not have galvanic isolation via
opto-isolator.
The measuring range of the analogue inputs can be set (see Operation
instr
uctions Profibus DP,
CONFIGURATION).
5.3 Assignment of the Profibus DP connection
X2 On this plug the bus signals and the galvanically isolated voltage supply for
the bus termination, as well as the bus termination resistors on the Profibus
DP board, are connected.
