KpModbus – function code 16 (10 hex) Write multiple

[MarCus0]

Hi Mikhail

There is a plan add other function codes to KpModbus.dll?
Specially 16(10hex) which is frequently used in modbus devices.
Will be nice even it will be available in comercial(paid) version

For that I checked few trial version of OPC servers just for this funcjonality but no one works soo easy as KpModbus plugin.

Hi,
Function 0x10 already supported. The driver KpModbus.dll uses 0x10 function if you tick Multiple checkbox for a command.

Hi

See screenschot.
Under dropbox is marked tick multiple.
I good understand that for single coil(0x) will be 05(0x05), multiple will be 15(0x0F) and for (4x)holding register 06(0x06)-for single and 16(0x10)-for multiple write? I’m not at home just have some test instalation at front.

Hi Marek,

That’s right. You can check here.
But the best way to check is watching communication log in Communicator.

hello, Mikhail. How does the automatic control module implement the 0x10 function code using the modbus protocol and simultaneously write four register addresses?

[Mikhail]

Hello,
Auto Control Module sends commands to Server. It is a universal logical module which is not protocol-dependent.
To configure particular Modbus commands, edit the Modbus template in the device properties in Communicator.
