Creating an IO Table
Creation of an IO Table whilst connected to a PLC causes the Actual IO Table in the hardware to be written to the
Registered IO Table. An IO Table can also be edited offline and stored to file, this method is usually employed
when designing a PLC's IO Table.
To create an IO Table, Select Create from the Options menu.
Slot Allocation
Use the following procedure to allocate a unit to a slot.
1, 2, 3...
Slots can also be allocated by transferring the rack information from the PLC. Refer to IO Table Component in this
chapter for information regarding transferring IO Table information from the PLC.
For CS/CJ/CP series PLCs, the IO fields for racks, slots and units information can be edited directly in the IO
Table tree.
Only those units in the Registered IO Table for CS/CJ/CP series PLCs, C200H (including C200HS/X/G/E) PLCs
and CV/CVM1-series PLCs can be edited.
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. Select an empty slot in the IO Table component.
2. Click the right-mouse button and select a unit. For Single and Multiple IO Units a
secondary selection is required from the right-mouse button menu. The type of PLC series
and individual rack configurations determine the units that can be installed and therefore
the content of the right-mouse button menu. The types of unit that can be selected are
described in following paragraphs.
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.
