Module EP-5261
Figure 145: 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 (IIN) either with 5Vdc or 24Vdc (parameterizable). Both supply voltage
outputs are protected against overcurrent.
