I connect the energy meter (RS-485 port) to CM1241 RS422/485  via Profibus cable.

In meter configuration 

ID -1

BARD RATE- 9.6

PARTY - NONE

RS-485 Configuration 

Port- 269 (as per hardware identifier)

BARD - 9600

PARTY - 0

MB_ADDRESS- 1

MODE - 0

DATA_ADDR - 40001

DATA_LEN - 50

DATA_PTR - MD200

Now MB_COMM_LOAD  Done= true

 MB_MASTER Done = false but 

Busy = true.

I have enclosed the image.

Hello,

try this:

Tip: verify the slave using modscan first. It’s a tool I personally can’t live without when dealing with Modbus.

I also personally prefer to save (as a receive buffer)Modbus data in “Array of word” as it matches Modbus using 16bit data. Then if I have a sequence (E.g. a case) I move them to correct destinations with appropriate scaling, and if needed creating 32 bit using slice access (myDint.w0 :=...)

MB_Master Busy = true

but Value didn't came.I have enclosed the setting snap shot.

If any other setting is there.

In this meter I had read the value in 30016 address via  modbus TCP .

METER setting: for remainder

Parity - 0

baud - 9600

stop bit -1

ID - 1

Below attach setting ok.

Value did't came for above setting
