PLC Setup
When connecting to a CVM1/CV-series CPU Unit, set the following communications
conditions for the PLC Setup.
Communications speed
Stop bit
Parity
Data length
Unit #
Note: Set the Host Link communications speed (baud rate) to 9600 bps or 19200 bps with
Either set the PLC Setup directly from a Programming Device (e.g. CX-Programmer), or
transmit the PLC Setup made at a Programming Device to the CPU Unit.
For details on the PLC Setup, refer to the SYSMAC CVM1/CV500/CV1000/ CV2000
Operation Manual: Ladder Diagrams (W202-E1-@).
• Unit # (SW3, SW4)
• I/O port selection (selector switch)
• Communication condition setting (DIP SW1)
• Terminator setting (selector switch)
Item
the Communications Setting menu item in the CX-Designer and the System Menu for
the NS-series PT. For details, refer to 1-4 Settings for Host Link.
Set these switches to 0.
Set this to RS-422A.
Set this switch to OFF.
Communication is executed in accordance
with the CPU bus unit system settings made
at the PLC. The initial values for the system
settings are as follows.
- Communications speed: 9,600 bps
- Parity: Even
- Xon/Xoff control: Not executed
- Communication method: Full duplex
- Stop bits: 2 stop bits
- Data length: 7 bits
Set this to ON.
Set the same baud rate as set at the NS-series PT (See note.)
