Initial Setup Procedure
Section 2-3
2-3-1 Selecting a unit number
1. Make sure that the PLC Power Supply is turned OFF before setting the Unit
number.
2. Set the switch to the desired unit number. Use a small screwdriver to make
the setting, taking care not to damage the rotary switch. The unit number
is factory-set to 0. Make sure that the unit number is unique on the PLC,
i.e. there must be no other CPU Bus Units with the same unit number.
3. Turn ON the PLC Power Supply.
After setting the unit number, the PLC CPU must now register the PROFI-
BUS-DP Master Unit, by creating an I/O table.
2-3-2 Creating an I/O table
An I/O table is used to identify Units connected to the PLC and to allocate I/O
to them. The I/O table is stored with the PLC CPU, and loaded at start up. If
any change is made to the Unit configuration of a CS/CJ-series PC, the I/O
table must be created again to register the Units to the CPU Unit.
Connecting a
Programming Device To create the I/O table, connect a Programming Device (such as a Program-
ming Console or Cx-Programmer) to the PLC.
Applicable Programming
Devices The following Programming Devices can be used with CS/CJ-series PLCs.
Programming Console
CX-Programmer and CX-Net
Model number: WS02-CXP @@ -EV2
The operations are explained here using a Programming Console. For details
regarding the Cx-Programmer and the Cx-Net, refer to the
Cx-Programmer
User’s Manual
.
Cx-Net is software that comes with Cx-Programmer and is automatically
installed when Cx-Programmer is installed.
Connecting Programming
Devices To connect a Programming Console, attach a CS/CJ-series Key Sheet and
then connect the Console to the CPU Unit’s peripheral port. (It cannot be con-
nected to the RS-232C port.)
Procedure for Creating an
I/O Table The procedure for creating an I/O table is shown here, taking as an example
an I/O table that is generated automatically for a PLC connected online. In this
example, a Programming Console is used for creating the I/O table. For an
explanation of how to create an I/O table using a Cx-Programmer, refer to the
Cx-Programmer User’s Manual .
Use the following procedure to create the I/O table.
