Modbus pause between telegrams

Giamba

Hi !
Please, do you know why when I put 30s to pause between telegrams in modbus chanel, I always have a short delay:

21:59:55.6940 => Sending: 00 A1 00 00 00 06 00 03 00 00 00 08 
21:59:55.7040 <= Receiving: 00 A1 00 00 00 13 00 03 10 03 F2 00 E5 01 FE 00 E4 02 8A 00 00 00 00 03 84

@Giamba It's not 30s but 0.5s. Check the read/write interval in the definition of the device...

Ok, thanks, I find it!

But, so, what's de "pause between telegrams" parameter ?

@Giamba The pause between telegrams can be used when communicating with devices that you send a command to make some measurement and the measurement takes some time and only after that time you can read the measured value. Then you use the pause between telegrams property.
