Description
When RYn8 is turned ON, the following data and signals are
set. At the same time, RXC turns ON. While RYn8 is ON, the
monitor values are kept updated.
1) When 1 station is occupied
Remote register RWrn: Data demanded by Monitor 1
(RWwn)
Remote register RWrn+1: Data demanded by Monitor 2
(RWwn+1)
Remote register RWrn+2: Answer code indicating normal
or error
2) When 2 stations are occupied
Remote register RWrn: Under 16 bits of data demanded by
Monitor 1 (RWwn)
Remote register RWrn+1: Upper 16 bits of data demanded
by Monitor 1 (RWwn)
Remote register RWrn+5: Under 16 bits of data demanded
by Monitor 2 (RWwn+2)
Remote register RWrn+6: Upper 16 bits of data demanded
by Monitor 2 (RWwn+2)
Remote register RWrn+2: Answer code indicating normal
or error
Turning RYn9 ON executes the processing corresponding to
the instruction code stored in remote register RWwn+2.
After completion of instruction code execution, the answer
code indicating normal or error is set to RWrn+2. At the same
time, RXn9 turns ON.
The point table No. and the home position return are selected
by RYnA to RY(n+2)5.

When the parameter No. PD22 setting is "
position control counter droop pulses is cleared at the leading
edge of RYnF. The pulse width should be 10ms or more.
When the parameter No. PD22 setting is "
pulses are always cleared while RYnF is on.
