Why does the host device detect an error after broadcasting a command to Omron E5EC?
The Controller does not return responses for broadcast or software reset commands.
How to fix a large temperature error (S.Err display) on my Omron E5EC?
A large temperature error or an input error (S.Err display) on your Omron Temperature Controller can be caused by an input type mismatch. Check the sensor type and reset the input type correctly. It can also be caused by the thermometer not being installed properly. Check the thermometer installation location and polarity and install correctly.
How to prevent Omron Temperature Controller communication data corruption due to environmental noise?
If the communications data is being corrupted by noise, try using a slower baud rate. Also, separate the communications cable from the source of the noise.
Why can't I always change set points on my Omron Temperature Controller?
If it's sometimes not possible to change the set points or RUN/STOP status on your Omron Temperature Controller, there may be noise interference. Connect terminating resistance to both ends of the communications line.
Why aren't the set points or RUN/STOP status changing for slaves on my Omron E5EC Temperature Controller?
If the set points or the RUN/STOP status will not change for any of the slaves, check that: * The wiring to the master (i.e., the Controller with communications unit number 0) is not correct. * The communications settings in the master are not correct.
What to do if the host device sends another command before receiving a response from the Omron Temperature Controller?
If the host device sent another command before receiving a response from the Controller, always read the response after sending a command.
How to set an end node for Omron E5EC Temperature Controller communication line?
If an end node has not been set at each end of the communications line on your Omron Temperature Controller, set or connect terminating resistance at each end of the line.
What to do if the Omron E5EC Temperature Controller isn't receiving the specified power supply voltage?
If the specified power supply voltage is not being supplied to the Controller, supply the specified power supply voltage.
What to do if the Omron E5EC Temperature Controller communication cable is broken?
If the communications cable is broken on your Omron Temperature Controller, replace the cable.
What to do if the Omron Temperature Controller communication line is disconnected?
If the communications line has become disconnected on your Omron Temperature Controller, connect the communications line securely and tighten the screws.
