MB2HAL write was created by vre

I have got this modbus 16 I/O module 485io.com/io-isolation-protection-board-...relay-led-p-373.html
This is the manual 485io.com/eletechsup/N4D3E16-1.rar

I have used this config to mb2hal and i can read in hal all 16 inputs with success

Code:

[TRANSACTION_00]
LINK_TYPE=serial
SERIAL_PORT=/dev/ttyS0
SERIAL_BAUD=9600
SERIAL_BITS=8
SERIAL_PARITY=none
SERIAL_STOP=1
SERIAL_DELAY_MS=500
MB_SLAVE_ID=1
FIRST_ELEMENT=129
PIN_NAMES=mb1,mb2,mb3,mb4,mb5,mb6,mb7,mb8,mb9,mb10,mb11,mb12,mb13,mb14,mb15,mb16
MB_TX_CODE=fnct_03_read_holding_registers

But i can't write 16 outputs.
How can make it to work ?
How can i send custom command with mb2hal like this?
(slave address)0x01 (function)0x06 (number of output)0x0001 (command)0x05 (delay time)0x00 (2Bytes CRC)

edit
If write 256(dec) to hal pin opens
and if write 512(dec) to hal pin closes
Also works function 16..

How to write values 256 and 512 to hal pins need a python script to convert boolean value to 16bit hex ?
