Connection to a PLC by the Host Link (RS-422A Type)
Section 2-5
Set the CPU Bus Unit settings directly from a Programming Device (e.g.,
SYSMAC Support Software).
For details on the CPU Bus Unit settings, refer to the
SYSMAC CVM1/CV-
series Host Link Unit Operation Manua
l (W205-E1-
@
).
Setting the Front Switches
Connecting to a CJ-series Serial Communications Unit
CJ-series: CJ1W-SCU41 (Port 1 is an RS-422A/485 port.)
Setting the Front Switches
Set the unit number of the Serial Communications Unit with the rotary switch
on the front of the Unit. Set the unit number with a flat blade screwdriver. Also,
set the communications mode switch to select 4-wire (RS-422A) communica-
tions and turn ON the terminator switch to enable the terminating resistance.
Allocation DM Area Settings for CPU Unit
Settings are written from the Programming Device (a Programming Console
or CX Programmer) directly into the allocated DM Area (PLC Setup) of the
Communications port 1
(RS-232C)
Communications port 2
(RS-232C/RS-422A)
I/O port selector switch
RS-422A
•
Unit # (SW3, SW4)
Set these switches to 0.
•
Communication condition setting (pin 1)
•
I/O port selection (selector switch)
Set this to RS-422A.
RS-232C
•
Terminating resistance setting (selector switch)
Set this to ON.
Set this pin 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.
- Baud rate: 9,600 bps
- Parity: Even
- Xon/Xoff control: Not executed
- Communication method: Full duplex
- Stop bits: 2 stop bits
- Data length: 7 bits
Unit number switch
Set the unit number between 0 and F
so that it will not duplicate the
numbers used in other Units.
Terminator switch
Turn ON to connect the terminator.
(Set terminator ON.)
Communications mode switch
Set the 2-wire/4-wire selector switch to
