19.1 Assignment of the customer inputs of the DeviceNet 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
to the Process Input Data 1 – 3 assembly object. The inputs are galvanically
isolated and internally connected to 0 V via pull-down resistors. In an uncon-
nected 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 DeviceNet 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 page 51,
CONFIGURATION).
19.2 DeviceNet connection assignment
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
DeviceNet board, are connected.
