6.3 MT-SICS Interface commands and functions

Many of the balances and scales used have to be capable of integration in a complex

computer or data acquisition system.

To enable you to integrate balances in your system in a simple manner and utilize their

capabilities to the full, most balance functions are also available as appropriate

commands via the data interface.

All new METTLER TOLEDO balances launched on the market support the standardized

command set “METTLER TOLEDO Standard Interface Command Set” (MT-SICS). The

commands available depend on the functionality of the balance.

Basic information on data interchange with the balance

The balance receives commands from the system and acknowledges the command

with an appropriate response.

Command formats

Commands sent to the balance comprise one or more characters of the ASCII character

set. Here, the following must be noted:

• Enter commands only in uppercase.

• The possible parameters of the command must be separated from one another and from the

command name by a space (ASCII 32 dec., in this description represented as /).

• The possible input for “text” is a sequence of characters of the 8-bit ASCII character set from 32

dec to 255 dec.

• Each command must be closed by CRLF (ASCII 13 dec., 10 dec.).

The characters C

, which can be inputted using the Enter or Return key of most entry

keypads, are not listed in this description, but it is essential they be included for

communication with the balance.

Example

S – Send stable weight value

Command S Send the current stable net weight value.

Response S

/WeightValue

/Unit

Current stable weight value in unit actually set

under unit 1.

/I Command not executable (balance is currently

executing another command, e.g. taring, or

timeout as stability was not reached).

/+ Balance in overload range.

/- Balance in underload range.

Example

Command S Send a stable weight value.

Response S

//////////

/////100.00

The current, stable weight value is 100.00 g.
