Cj1W-Ad04U - Omron CJ Series Operation Manual

Address of Data Range Error will be 100 or greater. (The value will be 100 if the first word of the Expansion Set-
ting Parameters is erroneous.)
For the correspondence between range error addresses and setting parameter or expansion setting parameter
addresses, refer to A-3 Correspondence Table of Analog I/O Unit Variables and CJ-series CPU Addresses. "m"
in the table indicates the first word allocated in DM. m = D20000 + (N × 100) (N: Unit number)
Unit Restart
To restart the Unit after the Initial Settings Parameters are changed or an error is corrected, restart
the Unit with the following methods.
The changes in the Initial Settings Parameters are reflected after restart.
• Reset the Controller from Sysmac Studio
• Restart from Sysmac Studio when initial settings parameters are transferred from Sysmac Studio.
• Reconnect the Controller power supply to reset the Controller.
• Restart from the program by a ResetUnit instruction.
• Restart using the system-defined variable. (Restart by changing the value from 0 to 1.)
A unit number from 00 to 95 is included in place of ** in *_CJB_SIO**Restart.
Precautions for Safe Use
When you restart the Unit after you change the Unit setting, first carefully check the safety of the
target device connected to.
Precautions for Correct Use Precautions for Correct Use
If the error persists after the restart, replace this Unit.
