Values for MPPT Hex Protocol Register 200C Device State

Hi,

the latest MPPT Hex Protocol documentation refers to Register 200C Device State but does not provide the accepted register values to represent Bulk, Absorption, Float.

What are they?

Thanks

Hi, its very similar to the other state one, 0x0201.

The device state vreg (0x0201) is read-only (for ve.direct) and it is always present. The link device state (0x200C) is writable and should only be present when external control (sync charging/ess/etc) is used by the device.

The goal is to have a separate register between telling what the device should do; and seeing what it actually does.

hello,

how can this register be read-only if the manual says, that it is needed to write to this register periodicaly to activate slave mode ?

i have a file from 2016 and one from 2018 (downloaded this year) with the same information to register 0201.

goodby

thanks Matthias, I'm syncing four non-bluetooth MPPT 100/30 to diy Lithium. Thanks also for the adaptive/normal absorption time switch.

PS forgot to mention Adaptive Mode needs "type" including in the Hex Protocol documentation.
