Photoeye Input Data Mapping
The photoelectric sensor (photoeye) inputs are mapped to the
1756-DNB module's input data file and then to the Logix5550
controller's input image table. The procedure for doing this using
RSNetWorx for DeviceNet software is described on pages 4-15 to 4-17.
The photoeye has no outputs to map.
Series 9000 Photoeye
Two input bits from the photoeye
will be mapped: the status bit
and the data bit.
The photoeye produces
one byte of input data in
response to the strobe
message.
