Allows the host to obtain the binary value of the content of A100E registers
All registers can be transferred in a single read request.
The below example reads registers 0 through 2 from slave 01:
ADDR FUNC START
REG HI
START
ERG
LOW
# OF
ERG HI
# OF
ERG
LOW
CHECK
01 03 00 00 00 03 05 CB
Slave answer is as follows:
ADDR FUNC BYTE
COUNT
REG
0
HI
REG
0
LOW
REG
1
HI
REG
1
LOW
REG
2
HI
REG
2
LOW
CHECK
01 03 06 00 0F 00 00 01 C0 74 B4
Value of register 0 is 15, register 1 is 0 and register 2 is 448.
Function 05 - Force Single Coil
Allows the host to force a single coil. In A100E the command is used to issue a ZERO, G/N, TARE or
POF reset command.
If the ZERO cannot be done (not enabled or weigh higher than the allowable limit) an “Illegal Data Value”
exception response will be generated
The below is a valid example:
ADDR FUNC COIL
#
HI
COIL
#
LOW
DATA
VALUE
HI
DATA
VALUE
LOW
CHECK
01 05 00 00 FF 00 8C 3A
The normal response is to retransmit the query message:
ADDR FUNC COIL
#
HI
COIL
#
LOW
DATA
VALUE
HI
DATA
VALUE
LOW
CHECK
01 05 00 00 FF 00 8C 3A
Function 06 - Preset Single Register
Allows the host to modify the contents of an holding register
The below example preset register 12 of slave 01 with 54:
ADDR FUNC REG REG DATA DATA CHECK
