Function Codes
The function code is a one character ASCII code in the range ‘A’ to ‘Z’ and
‘a’ to ‘z’.
Read Data (F) or (R)
The data field of this message contains a two-character hex variable ID.
The data returned is ID dependent. Note that the F and R commands are
equivalent.
Example:
Master:
>01F050C[CR]
Slave:
A1234540[CR]
The example requests variable ID 5 from unit 1. The response is an ac-
knowledge with the value 12345.
Write Data (H) or (W)
The data field of this message contains a two-character hex variable ID.
Note that each system variable will have an associated format. The data to
be written follows the ID. The data format is ID dependent. Note that the
H and W commands are equivalent.
Settings are saved in non-volatile EEPROM memory. Each variable
ID location can be only be written to a maximum of 10,000 times.
Exceeding the maximum may cause loss of data.
Example:
Master:
>02H3B123.417[CR]
Slave:
A[CR]
The example writes the value 123.4 to ID 3B on unit 2. The response is a
simple acknowledge.
