5.17 Serial Communication Module EP-5261
Digital Interface Module 5261
Connection Diagram EP-5261
Serial data can be exchanged between the PLC and a data terminal device using the EP-5261
communication module. The device (such as a barcode scanner, printer) can be connected through
an interface type RS232, RS485 or RS422.
The data transfer rate can be parameterized between 300 and 115200 bps. The process data length
can be parameterized to be 8 byte or 16 byte. A terminating resistor can be parameterized 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
) either with 5VDC or 24VDC (parameterizable). Both supply voltage outputs are protected
IN
against overcurrent.
