If the host device detects the absence of a response as an error before it receives the response from the Omron Controller, shorten the send data wait time in the Controller or increase the response wait time in the host device.
How to prevent communications data corruption due to noise with my Omron E5EN-H?
If the communications data is corrupted by noise when using the Omron Controller, try using a slower baud rate. Separate the communications cable from the source of noise. Use a shielded, twisted-pair cable for the communications cable. Use as short a communications cable as possible and do not lay or loop extra cable. Do not run the communications cable parallel to a power line to prevent inductive noise. If noise countermeasures are difficult to implement, use an Optical Interface.
What to do if the host device sent another command before receiving a response from the Omron E5EN-H?
If the host device sent another command before receiving a response from the Omron Controller, always read the response after sending a command (except for broadcast or software reset commands).
What to do if the host device sent the next command too soon after receiving a response from the Omron E5EN-H?
If the host device sent the next command too soon after receiving a response from the Omron Controller, wait for at least 2 ms after receiving a response before sending the next command.
What to do if the communications line becomes unstable when the Omron E5EN-H's power is turned on?
If the communications line became unstable when the Omron Controller’s power was turned ON or interrupted, and the host device read the unstable status as data, initialize the reception buffer in the host device before sending the first command and after turning OFF the power to the Controller.
Why is the host device detecting the absence of a response as an error after broadcasting a command to my Omron E5EN-H?
The Omron Controller does not return responses for broadcast or software reset commands, so the host device detecting the absence of a response as an error is normal.
