PART 2: CX-Server PLC Tools
CHAPTER 3 – IO Table Component
Single and Multiple Units
Points with an IO Type of Input, Output or Input/Output can be applied to the IO Table component. Each point
contains a name and an address indicating its position in PLC memory. The information contained within a point
can be read or updated by the controlling system and its status and content stored in the system's database. An
application accesses this point data by establishing a link between the application and the database. A point can
have the same address as another and any comment entered against this address applies to all points at that
location.
All PLC series support 8-point, 16-point, 32-point and 64-point Units. CV-series PLCs and CS/CJ/CP-series
PLCs also support 128-point and 256-point Units.
Refer to the Run Time manual for an introduction to points.
Counters, Position Controller, Numerical Control and ASCII Units
Use the following procedure to apply unit settings to Counters, Position Controllers, Numerical Control and
ASCII units.
1, 2, 3...
Additionally for Counters, Numerical Control and ASCII units, for CV-series PLCs and CS/CJ/CP series PLCs,
the CIO and DM Address range need to be specified; refer to Chapter 3 - Software Switches for further
information.
Interrupt Units
Interrupt units are automatically assigned until the maximum number of units has been reached.
Sysmac-Bus Master Unit and Remote Terminals
If the Sysmac-Bus Master option is selected from the context menu, the hierarchy in the IO Table component can
be further expanded to expose the Remote Terminals and IO Terminals that form part of the SYSMAC-BUS
option. Use the following procedure to apply unit settings to Sysmac-Bus Master.
1, 2, 3...
The Sysmac-Bus Master unit provides two types of slave units that can be applied to the slave rack in the same
manner as a normal rack:
♦ C500H Remote Terminal (RT);
♦ C200H Remote Terminal (RT).
Any units on the slave racks or other Remote IO Units connected to the master are allocated IO words according to
the slot where the master is located.
For C1000H and C2000H PLCs, Word multipliers are required to set the base address of IO Terminals on each
SYSMAC-BUS Remote Master.
SIOU/Communications Units
SIOU/Communications Units can only be set up for CV-series PLCs and CS/CJ/CP series PLCs.
For CV-series PLCs SIOU/Communications Units the following Unit Setup and Software Switches setup can be
performed:
♦ Basic (Software Switches setup only);
♦ DeviceNet Master (Software Switches setup only);

Note: Any slots allocated must be verified to ensure that the Real IO Table has been setup up
correctly.
1. Allocate a slot to be a Counter unit, Position Controller unit, Numerical Control unit or
ASCII unit. The Enter SIOU Details dialog is displayed.
2. Enter valid settings for the Unit Number field, Address per Unit field, Input Words field
and Output Words field. Valid settings exclude those settings that have already been used.
3. Select the OK pushbutton to complete the operation or the Cancel pushbutton to abort the
operation.
1. Allocate a slot to be a Sysmac-Bus Master unit. The Enter RM Number dialog is displayed.
2. Select a unit number from the Unit Number field, either 0 or 1.
3. Select the OK pushbutton to complete the operation or the Cancel pushbutton to abort the
operation.
