Request: 01 10 18 DA 00 02 04 00 00 00 00 D4 8C
01 = controller address
10
= Modbus command (Write Multiple Registers (page
138))
18 DA
= Register address: Object (46363) – 40001 = 6362
DEC => 18DA HEX
00 02 = number of Modbus registers (user & password)
04 = data length in bytes (00 00 00 00)
00 00 00 00 = User identification “00 00” & password “00 00”
8C D4
= Check field calculation (page 143) (write LSB
MSB !)
Response: 01,10,18,DA,00,02,66,93
01 = Controller address
10 = Modbus command
18 DA = Register address
00 02 = number of written Modbus registers

01 = controller address
10 = Modbus command (Write Multiple Registers (page 138))
18 D6
= 6538 object for engine commands (46359) – 40001 = 6358 DEC => 18D6
HEX
0003 = number of Modbus registers
06 = data length in bytes (01FE0000+0001)
01FE0000 = argument for Engine start (Commands for IGS-NT (page 72))
