E16V3 - No reply if command issued just after another command to another device on th - ldebacker - 02-22-2026
Hello,
I have 2 E16V3 installed as 2 different slaves on the same modbus.
When I send a command to each in isolation, I receive a response within a few milli-seconds from the E16V3.
But when I send a command to the second E16V3 immediately after successful response from the first one, then I never receive the response from the second device.
It seems that the second E16V3 is puzzled by the activity on the bus that is not intended to himself.
I have to retry the command to the second E16V3, or wait (20 miliseconds for example) before sending the command to the second E16V3
I can help troubleshooting further if needed.
BRs,
Laurent
