General information for the connection to PLC
The BARTEC system of the BCS36x8ex series consists of a hand-held scanner (corded or Bluetooth) and an associated
universal supply module(USM) or base station.
The hand-held scanner can be connected to a PLC via these associated components.
All used interfaces of the USM (USB, RS232, RS422 and RS485) can be connected to a PLC.
There are a number of different manufacturers for PLCs. The connection of a hand-held scanner depends on the availability
of an interface to the PLC and the ability of the PLC to process the incoming data. The PLC must support the open ASCII
protocol.
There is no compatibility list existing.
The following must be observed when connecting the handheld scanner to a PLC:
What interfaces are available on the PLC/PLC?
The USM supports the following interfaces.
-
USB-SPP (virtual serial interface)
-
RS232
-
RS422
-
RS485
The PLC supports the open ASCII protocol.
What interface parameters are set on the PLC?
All interconnected components must be set to the same parameters. Otherwise, the communication can not work
correctly or not at all.
-
Baud Rate
-
parity
-
Stop Bit
-
Data Bit
-
Hardware/Software Handshaking
The way of processing the data at the PLC and what has to be set at the scanner is the responsibility of
the plant operator.
E.g. a serial interface has no intelligence of its own and cannot process incoming data independently. This
means that the controller must monitor the serial interface and process incoming data (read/write routine).
