modbus 485 error ! :(

[Dré]

What if you delete both devices and use read test, does it read from both meters correctly?

if i remove both devices and do a RTU scan, he can find both devices.
if i already had add one, he can't find the second device.

with a read test, i dont get the same results as when i add the device and see on the groupadresses. (see attachment)
