chapter 2 that the START button is bit 1 and the STOP button is bit
0. Therefore, the addresses for the RediSTATION inputs are:

STOP M1:2.0.0
The input from the photoeye will appear in the M1 file for the
device in slot 2 as word 0, bits 8 to15

input bit is bit 0. Therefore, the address of the photoeye input is:
M1:2.0.8
