Serial communication module UR20-1COM-232-485-422 (Order No. 1315750000)
Serial data can be exchanged between the PLC and a
data terminal device using the UR20-1COM-232-485-422
communication module. The device (e.g. barcode
scanner, printer) can be connected via an interface type
RS232, RS485 or RS422. The data transfer rate can be
parameterised between 300 and 115200bps. The process
data length can be parameterised to be 8byte or 16byte. A
terminating resistor can be parameterised for the RS485 and
RS422 interface respectively.
The communication status is indicated by two LEDs on the
respective plug.
The module electronics supply the connected data terminal
device with power from the input current path (I
IN
) either
with 5VDC or 24VDC (parameterisable). Both supply volta-
ge outputs are protected against overcurrent.
