Creating an I/O Table Section 3-7
Note 1. Use a power supply that meets these specifications.
2. If the power supply is separate from a node, make sure that these specifi-
cations are met at the node’s terminal block.
3. Turn ON the Unit’s power supply either before or at the same time as the
CPU Unit’s power supply. If the CPU’s power is turned ON first, a commu-
nications error may be generated.
4. Use a power supply with double or reinforced insulation.
5. Confirm that the Power Status Bit is ON before starting communications.
(Refer to Power Status (Bit 15) in 4-3 CIO Area Allocations.)
6. In the IEEE802.3 standards, the transceiver power supply specifications
require a voltage of 11.28 V (12 V – 6%) to 15.75 V (15 V + 5%) at the
transceiver inputs. The voltage output by the Ethernet Unit takes into ac-
count a voltage drop at the transceiver cable.
3-7 Creating an I/O Table
After the hardware settings and connections have been completed, turn ON
the power supply to the PC and create an I/O table.
3-7-1 I/O Table Overview
An I/O table is used to identify Units connected to the PC and to allocate I/O
to them. If any change is made to the Unit configuration of a CS/CJ-series PC,
an I/O table must be created to register the Units to the CPU Unit.
3-7-2 Connecting Programming Devices to the PC
To create the I/O table, connect a Programming Device (such as a Program-
ming Console or CX-Programmer) to the PC.
Applicable Programming
Devices
The following Programming Devices can be used with CS/CJ-series PCs.
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.)
3-7-3 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 PC connected online. In this
example, a Programming Console is used for creating the I/O table. For an
Model number Key Sheet (required) Recommended cable (required)
C200H-PRO27-E CS1W-KS001-E CS1W-CN224 (cable length: 2.0 m)
CS1W-CN624 (cable length: 6.0 m)
