What to do if Omron Monitor says 'Input address is out of range'?
If the Omron Monitor displays 'Input address is out of range', it means the input address (bit/word) is incorrect. To solve this, enter the correct address.
Why can't I change time/counter present values on my Omron Monitor?
If the Omron Monitor displays 'Cannot change time/counter present values', it means a timer/counter address was selected in the I/O Monitor, and the Change Button was pressed while connected to a CJ2 CPU Unit. To resolve this, display the timer/counter instruction, select the timer/counter, and then change the present value.
What does 'Cannot read specified task because the task is read-protected' mean on my Omron Monitor?
If the Omron Monitor displays 'Cannot read specified task because the task is read-protected', it means you're trying to access a task with read protection enabled. To solve this, use the CX-Programmer to clear the task read protection for the PLC, and then restart the Ladder Program.
How to fix 'Cannot read the program. UM is read-protected' error on Omron Monitor?
If the Omron Monitor displays 'Cannot read the program. UM is read-protected', it indicates that UM read protection is enabled for the PLC. To resolve this, use the CX-Programmer to clear the UM read protection for the PLC, and then restart the Ladder Program.
How to change present value in Omron Monitor when it says 'Cannot change present value in run mode'?
If the Omron Monitor says, 'Cannot change present value in run mode', it means you're trying to change the timer/counter value while the device is in RUN mode. To fix this, switch to MONITOR mode or PROGRAM mode before changing the present value.
What to do if Registered Host Info and Comm Settings are not matching on Omron Monitor?
If the Omron Monitor displays 'Registered Host Info. And Comm. Settings not matching', it means it failed to read the communications setting, or the communications port for the PLC is not set. To resolve this, change the communications setting in the System Menu of the PT after pressing the Exit Button.
How to fix Omron Monitor when Ladder Monitor does not start?
If the Omron Monitor displays the message 'Ladder Monitor Does Not Start', it could be due to missing files on the Memory Card or a defective Memory Card, or a corrupted system program. Try transferring the files from the CD-ROM to the Memory Card again, and ensure the Memory Card is readable on a computer. If the system program is corrupted, reinstall it. If the issue continues, contact your OMRON representative.
Why does my Omron Monitor say the destination address is incorrect?
If the Omron Monitor shows 'Destination address is incorrect', it means a FINS command sending error occurred due to an incorrect destination address, or corrupted network and node address data. To fix this, an error message box will appear. Press OK to exit. If the Change Host Dialog Box appears, change the connected host using the Change Host Button. If not, access the Change Host Dialog Box via the Menu Button. If neither works, exit and adjust the communication settings in the System Menu.
