Photoeye Input Data Mapping
The photoelectric sensor (photoeye) inputs are mapped to the
1747-SDN module’s M1 file and then to the SLC 500 processor’s input
data file. The procedure for doing this using RSNetWorx for DeviceNet
software is described on pages 4-12 to 4-15.
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.
