Template for Poll

[DV-FB]

Hi, after successful RTU to TCP mod,
Maybe this request is not so fast to implement or not useful somehow?
Up to You to make the discussion.

Since sometimes there are on the bus different IDs (same or different hardware,

If we could use a definable template where the poll will get the info to keep scanning in sequence,
to get different registers one after the other, something like a list:
ID - Address - Length

Example of list to scan 2 SDM630 units for L1 Voltage, L2 Voltage and L3 Voltage:
2, 1, 2
2, 3, 2
2, 5, 2
3, 1, 2
3, 3, 2
3, 5, 2

Feasable? Would be very cool to check before final code writing to be sure all registers are ok understood.

Best regards,

It's true that at the moment you can only debug one device at a time, so reading multiple devices sequentially isn't supported yet. Multiple client connections are on the roadmap, though!

Is it not possible to request a single range, like 2, 1, 6?

I know some devices don't allow reading full ranges at once because certain registers in between are blocked or unavailable. If that's the case, you can work around this in Modbux by defining a datatype for the registers and checking the "Group end" checkbox in the register configuration. This forces the app to split the request and read the registers sequentially instead of as one single block.

Read Configuration

Let me know if that helps!

Hi,
Didn't know this option was available, once I typenamed a register, and read some other registers this way, with polling I get already part of the result I mentioned before, as then only need to change ID to readout similar devices. Already big step forward, thx
