Hello,

There are 2 issues with the documentation of the 4 dip switches to set the slave ID on the bus.
Let's call, from left to right, the 4 dip switches respecively A0 A1 A2 A3.

1/ 
The documentation mentions that when A3 is in OFF state, this means the outputs are controlled by the input terminals (and when in ON state, it is controlled by MODBUS).
It is actually the reverse: When A3 is in OFF state, the device is controlled by MODBUS.

2/
The documentation specifies that when identifying the slave id, the value of the slave id is:  (A0 * 1  + A1 * 2 + A2 * 4) + 10.
so: A0=ON A1=OFF A2= OFF should give  slave ID  (1 * 1 + 0 * 2 + 0 * 4 ) + 10 = 11 (according to the table in the documentation)

It is actually the reverse: from trials/errors, the formula to apply seems to be (A0 * 4 + A1 * 2 + A2 * 1) + 10
so: A0=ON A1=OFF A2= OFF is, in reality slave ID  (1 * 4 + 0 * 2 + 0 * 1 ) + 10 = 14 (from experience).

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
