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.
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.
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 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.
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 fix 'Cannot change the value because timer/counter mode differs in Ladder Monitor and PLC' error on Omron Monitor?
If the Omron Monitor displays 'Cannot change the value because timer/counter mode differs in Ladder Monitor and PLC', it means the timer/counter operating mode setting is different for the Ladder Monitor and the connected PLC. Restart the Ladder Monitor to resolve this.
Why does my Omron Monitor say 'Selected program section not found'?
If the Omron Monitor displays 'Selected program section not found', it means the program section matching the specified conditions cannot be found. This can occur when searching beyond the beginning/last program section or when the specified instruction doesn't exist in the program. To resolve this, check the search conditions.
How to fix 'The step number is out of range' error on Omron Monitor?
If the Omron Monitor displays 'The step number is out of range', it means the input value for the step number (program address) is incorrect. Enter the correct value to resolve this.
Why Omron Monitor says 'Cannot remove memory card because Ladder Monitor is started from memory card'?
If the Omron Monitor displays 'Cannot remove memory card because Ladder Monitor is started from memory card', it means you're trying to remove the Memory Card while the Ladder Program is running from it. To remove the Memory Card, first exit the Ladder Monitor, and then perform the operation in the Initialize Tab Page in the System Menu.
