Data Interfaces
Connecting a printer
The COM1 standard interface, the optional UniCOM universal interface or both can
be used as a printer interface.
Use as a communications interface
The data protocol can be set to the following operating modes for operation as a
communications interface:
– SBI (factory setting)
– XBPI-232
– XBPI-485 (UniCOM only)
– MP8 binary (COM1 only)
– SMA
– Profibus
– Ethernet
Both communication interfaces can be operated independent of each other
(e.g. data transfer and control via a PC using the optional UniCOM interface with
simultaneous printing via the COM1 printer interface). During data communication,
each interface can use a different protocol, e. g. Com1 with SMA and UniCom with
XBPI.
In SBI operation, an indicator and connected weighing platform can be controlled
using ESC commands from the PC via the communications interface (COM1 or
UniCOM) (see page 105).
Each device can only be configured once for two interfaces (COM1 and UniCOM).
Device include:
– WP-2
– Analog output
If you attempt to reconfigure a device that has already been configured to another
interface (e.g. WP2 to COM-1) a second time (to UniCOM), the error message INF 74
appears.
