10-10 The Use of Analog Option Board
10-10-1 Procedure
Mount the analog option board into the option port.
Connect to the analog input/output device.
Two methods:
1.
DipSW4/DipSW5 set ON: TOOLBUS auto-detect
2.
DipSW4/DipSW5 set OFF: Set communication protocol in PLC settings to
TOOLBUS, 115200bps
Wait until the analog option board finishes initialization and works normally.
Read the analog input data/write the analog output data.
Note
(1) If PLC communication protocol setting is error, the option board will al-
ways try to link the PLC, and the error LED will flash.
(2) Only when the initialization process has finished (AR435.14/15 sets on),
user can use the A/D conversion data or write the D/A output data.

CPU Unit service
monitoring error
Service from the
CPU Unit was
not completed
within the fixed
interval.
Check and cor-
rect the CPU
Unit's operating
environment.
Check serial
communication
setting.
A435.14 or
A435.15
will be OFF
AD/DA conversion will stop.
The analog input conversion
data stops refreshing and the
analog output conversion out-
put becomes 0V.
Option board
error
An error
occurred in the
Analog Option
Board.
Restart the CPU
Unit. Replace
the Analog
Option Board if
the error recurs.
Flashing
Communication
error
The communica-
tion between
PLC is out of ser-
vice
Check if PLC is
running nor-
mally.
A435.14 or
A435.15
will be OFF
AD/DA conversion will stop.
The analog input conversion
data stops refreshing and the
analog output conversion out-
put becomes 0V. If the commu-
nication recovers from error, the
AD/DA conversion will start
again.
Connection with the analog
input/output device
Make the ladder program
Mount the analog option
board
