Why is the MS indicator lit red on my Omron ERT1 Network Hardware?
If the MS indicator on your Omron Network Hardware Slave Unit is lit red, it means the Slave Unit is malfunctioning. The suggested solution is to replace the Slave Unit.
What to do if the MS indicator is flashing red on Omron Network Hardware?
If the MS indicator is flashing red on your Omron Network Hardware, it could be due to an illegal rotary switch setting. Check the switch settings and restart the Slave Unit. Alternatively, there might be an error in the Slave Unit's EEPROM memory data. To restore the default setting, set the rotary switches to FF hex, cycle the power supply, and then set the rotary switches to 00 hex. If the MS indicator continues to flash red after restoring the default settings, replace the Slave Unit.
How to hold outputs on Omron ERT1 when communications errors occur?
If your Omron Network Hardware is set to clear outputs for communications errors, change the setting to hold outputs for communications errors.
How to clear outputs on Omron ERT1 when communications errors occur?
If your Omron Network Hardware cannot clear outputs when communications errors occur, change the setting to clear outputs for communications errors.
Why is the Unconnected Line Detection Status Flag ON on Omron Network Hardware when the sensor power supply is connected?
If the Unconnected Line Detection Status Flag turned ON even though the sensor power supply was connected to your Omron Network Hardware, it's likely due to low current consumption (Output current: 3 mA max.). You should disable unconnected line detection for that input so that the unconnected line detection function does not operate.
Why is the Disconnected Line Detection Status Flag ON on Omron ERT1 Network Hardware when the external load is connected?
If the Disconnected Line Detection Status Flag turned ON even though the external load was connected to your Omron Network Hardware, it's likely because the current consumption is low (Output current: 3 mA max.). Disable disconnected line detection for that output so that the disconnected line detection function does not operate.
How to fix the delay with ON and OFF timing for input values on Omron Network Hardware?
If there is a delay with the ON and OFF timing for input values on your Omron Network Hardware, it might be due to an input filter being set. Set the input filter value to No Display. Alternatively, change the input filter to an appropriate value.
How to disable the Unconnected Line Detection Status Flag for unused input on Omron Network Hardware?
If the Unconnected Line Detection Status Flag turned ON for an unused input on your Omron Network Hardware, it means unconnected line detection is enabled for that unused input. Disable unconnected line detection for that input.
How to disable the Disconnected Line Detection Status Flag for unused output on Omron ERT1?
If the Disconnected Line Detection Status Flag turned ON for an unused output on your Omron Network Hardware, it indicates that disconnected line detection is enabled for the unused output. To resolve this, disable disconnected line detection for that output.
What to do if the NS indicator lights red without flashing green on Omron Network Hardware?
If the NS indicator lights red without flashing green on your Omron Network Hardware, check the node addresses of all nodes and change the settings as required so that each node has a unique node address.
