Subject: Modbus write register update when locally modified

Hi all,

I use Asyn (v4.19) ModbusTCP (v2.4) driver with longout record to write a consign.
when the plc is switched to Local control mode and consign is locally modified, when the plc is back in remote control mode, the record hosting the consign is not updated with the new current value.

I've checked that the Modbus table is actually updated.
Is it possible to have the record updated in such circumstance ?
Such Local/Distant transition doesn't fall into the Disconnect/Reconnect scope.
