Communication error detection on the
F X O N
PC side
To detect a communication ermr (i.e. communlcations stoppage) at the
FXON,
follow this procedure.
1. Connect the
F X O N - ~
6NT ECM terminal
t o
the 246 terminal.
Note:
If
a communication error
OCCUIS,
all the input points of the
F X O N - ~
6NT will reset.
2. Select one of the input signal points of the FXoN-16NT (Xn*), and set the A Sen- program so
that the selected input slgnal point is always ON.
3. On the FXoN side, Xn* is on during normal communication.
If
a communicatlon error is detected,
Xn* will be turned OFF. From this ONOFF status change, a communcatton error can be detected.
