6.5 LocalCAN universal interface
As an option, your PG-S balance can be retrofitted with a LocalCAN universal interface. As you can attach up to five
peripheral units at the same time, it offers you a high degree of flexibility in data interchange.
Peripheral units (see Section 7.3) from METTLER TOLEDO which have the connection cable as part of their standard
equipment can be attached in a simple manner to the balance.
The communication is particularly well supported by the commands of the standard and extended command set. The
reference manual (705184) that you received with the LC-RS or LC-CL cable describes the functioning of these commands
in an easily surveyed manner.
The features and benefits of the LocalCAN universal interface can be summarized
as follows:
- Attachment of up to five peripheral units to a balance at the same time.
- Support of standard interfaces such as RS232C or CL.
- Rugged, 4-pin connector with reversed voltage and pullout protection.
- Dependable data transfer thanks to built-in CAN controller.
- Open cabling system, i.e. each peripheral unit except auxiliary displays have
an additional connection.
- Simple configuration of the parameters without recourse to the operating
instructions of the PG-S balance.
The versatile features of the PG-S balances regarding documentation of the
results can not be utilized to the full until a printer, e.g. the LC-P45 from METTLER
TOLEDO is attached. The printed results make a decisive contribution to a simple
working procedure following GLP/GMP.
