Communication Port PLC Parameters

Communication Port

• The Communication Port PLC parameter encompasses the Ch 1 and Ch 2 PLC parameters for serial communication.

Ch 1

Supported PLC Series
XPnF	XPnE	CPnE/F	CP4C/D/U	CP	PLC-S
✓	✓	✓	✓	✓	✓

• The default communication type for channel 1 is RS-232(C).
• The station number is a unique identifier typically used for Modbus.
  • The value range is 0 ~ 254.
• The baud rate is the communication speed in bit per second (bps).
  • The ranges are:
    • 300
    • 600
    • 1,200
    • 2,400
    • 4,800
    • 9,600
    • 19,200
    • 38,400
    • 57,600
    • 115,200
• The parity is used for error checking in data transmission.
  • This can be set to odd or even.
• The data bit specifies the number of bits in a packet.
  • This can be set to 7 or 8 bits.
• The stop bit defines the end of a packet.
  • This can be set to 1 or 2.
• The response delay is the time, in milliseconds, before the PLC expects a response from the serial device.
