Photoeye Input Data Mapping
The photoelectric sensor (photoeye) inputs are mapped to the
1771-SDN module’s block transfer read data table and then to the
PLC-5 processor’s input data file. The procedure for doing this using
RSNetWorx for DeviceNet software is described on pages 4-14 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.
