Communication Protocol
The EMO‐3000’s ASC communication format returns an ASCII string in engineering units, in some cases
with the engineering units attached. You can choose whether the variable will be in engineering units or
"normalized" (Hertz/Pulses). The protocol format is:
^ means “add one letter or digit”; ^^ means add two letters or digits, ^^^ means add three letters or
digits, etc.; “cr” means “carriage return.”
Reading: #01E100cr
^
....
Pound sign is the indication that ASC form is to be used
^
^
....
Channel number 01...FE . These are hex notations.
Going through the Keyboard communication the regular channel
number is used. Going through the PLC input the channel number
is a sum of the channel number and the channel offset.
^
....
E means that the information returned should be in engineering
units. N means normalized.
^^^
....
Three-digit command number 100 to 999. Not all the numbers are
implemented and more info is forth coming.
^
....
Carriage return character (decimal 13 or hex 0D ).
