Setting Communication Specifications (RS-232C/422 - Non-procedure)

Communication specifications such as communication speed and IP addresses are set for serial interface (RS-232C/422 connection) communication.
Setting Communication Specifications (Ethernet - Non-procedure)
Important
  • Use the same communication specification settings for the controller and the external device.
Note
  • During setting of communication specifications, input signals cannot be handled.However, the input status can be checked with [Confirmation].
    Checking Communication Status (Non-procedure)
  • When data is output via serial communication, output is suspended while communication specifications are being set.
  1. On the Main screen, tap the [System] menu - [Communication] - [Serial] - [RS-232C/422].
    The Serial window is displayed.
  2. Tap [Setting] to set communication specifications.

    Description
    Interface
    • [RS-232C]
    • RS-422
    Adjust to the PC communication specifications.
    Baud rate [bps] [Note 1]
    • 2400
    • 4800
    • 9600
    • 19200
    • [38400]
    • 57600
    • 115200
    Adjust to the PC communication specifications.
    Data length [bit]
    • 7
    • [8]
    Adjust to the PC communication specifications.
    Parity
    • [OFF]
    • Odd
    • Even
    Stop bit [bit]
    • 1
    • [2]
    Flow control
    [OFF]
    Flow control is not performed with software.
    If the time in which there is no response from external devices reaches the timeout setting time, a timeout error occurs and an error message is displayed in the window.The parallel interface ERROR signal also turns on.
    Xon/Xoff
    Flow control is performed with software.Data is sent according to the Xon/Xoff codes from external devices.
    Delimiter
    • [CR]
    • LF
    • CR+LF
    Adjust to the PC communication specifications.
    Timeout [s]
    1 to 120
    [5]
    Set the time in which a timeout error will occur in seconds.
    [Note 1]: If a speed of [38400 bps] or higher is selected, effective communication cannot be guaranteed depending on the cable length because speeds of over 20 kbps are not defined in RS-232C standards.In these cases, set the communication speed at [19200 bps] or lower.
  3. Tap [OK].
    The settings are confirmed and the Serial window closes.
