Bit 0 InĆPosition
The 1771-M3 controller turns on this bit when following error is less than
twice the in-position band value programmed in the parameter block
(word 11). When the in-position bit is on, it indicates that the axis has
moved to within a specified distance of the programmed end point.
Bit 1 Done
The 1771-M3 controller turns on this bit when the 1771-ES expander has
finished feeding the axis for a programmed move or finished a dwell.
Bit 2 Ready
The 1771-M3 controller turns off the ready bit after power-up or after you
execute the reset command. The controller turns on this bit when it
receives valid parameter-block values. When the ready bit is on, the
1771-M3 controller is ready to respond to commands you issue through
the command block.
