Modbus/tcp - Direct Device Writes - double send write

Postby piergiorgio_grasseni/smigroup_net » Thu Dec 05, 2019 1:57 pm

Hi,

if enable Direct Device Writes synchronization mode for device registers of a MODBUS/TCP device, when change the value of device registers the modbus drive of AG send the write command to device for two times
Why?
If use normal synchronization mode the write command is sended one time.

Thanks

Piergiorgio! Please send us AggreGate device settings.

We want to see where are you selecting Direct Device Writes synchronization mode.

Hi, set in "Device Settings Synchronization Options" tab of device setting, in "Synchronization mode" column, for every declared tag in write.
I attached image.
