To collapse the IO Table, select this icon.
For CV-series PLCs, SIOU units are shown on the IO Table tree as a separate rack. For CS1-series PLCs,
SIOU units are all integrated into the main rack.
Whilst in online mode operations can be selected that affect the PLC, for instance creating an IO Table. These
options are only available when the PLC is in the correct mode of operation for programming.
The IO Table component can be forced to be displayed in focus by selecting
Always on top
from the
Options
menu.
For moving, resizing, maximising, minimising and closing windows, refer to Microsoft Windows online help for
further information.
Access to the IO Table component is from the invoking application or via the CX-Net Network Configuration
Tool. Refer to
Chapter 8 - CX-Net Network Configuration Tool
for further details.
To close the IO Table dialogue, select the
Close
button in the title bar.
Unit Settings
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…
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.
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 CS1-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 CS1-series PLCs, C200H (including C200HS/X/G/E) PLCs and
CV/CVM1-series PLCs can be edited.
Note:
Any slots allocated must be verified to ensure that the Real IO Table has been setup
up correctly.
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 CS1-series PLCs
also support 128-point and 256-point Units.
Refer to the Run Time manual
for an introduction to points.
