Description
Standard mode
(= Configuration mode)
In this mode, the digital indicator can be configured. Responses
will only be transmitted on request.
The current measured value can be queried via “A↵”.
Sending mode
Measured values are sent cyclically. The cycle corresponds to
the set measuring time.
Cancel sending mode
The sending mode is cancelled on receipt of “> ↵” and the instrument returns to
standard mode.
Activate sending mode
Restart the digital indicator or transmit the command “S ↵”.
Protocol structure
Display values are transmitted in ASCII format. Minus signs and decimal points can
be displayed directly on a terminal display or processed by a PLC. Leading spaces
are disabled with transmission. With an over- or underrange, hyphens are transmitted
“- - - - - ↵”.
Example: “0.00 ↵”; “-9.99 ↵” ; “999.99 ↵”; “-123.45”; “ - - - - - ↵”; “Lbr ↵”
The display values can be processed or stored on a PC via a terminal program.
