PC to PLC Communications
The IO Table component permits the transferring of data to and from the PLC and allows comparisons to be
made between data stored on the PC and the PLC.
Transfer an IO Table from a PLC
The
Transfer from PLC
option loads the Registered Table into the CX-Server IO Table, replacing the currently
displayed setup. The IO Table can also be part of a general transfer which may, for example, include
transferring program and memory data from the PLC. Use the following procedure to transfer an IO Table
from the PLC.
1, 2, 3…
1. Ensure the PLC is online before activating the IO Table component.
2. Select
Transfer from PLC
from the
Options
menu to transfer an IO Table from the PLC.
The IO Table component is refreshed with the details from the PLC.
Transfer an IO Table to a PLC
The
Transfer to PLC
option loads the CX-Server IO Table into the Registered Table: this is only available to
C2000, CV and CS1-series PLCs. The table can be transferred to the PLC at any time (when the PLC is online)
but the operation can be delayed until other configuration settings have been made and then the complete
configuration can be transferred to the PLC via the PLC Setup component. Use the following procedure to
transfer an IO Table to the PLC.
1, 2, 3…
1. Ensure the PLC is online before activating the IO Table component.
2. Select
Transfer to PLC
from the
Options
menu to transfer an IO Table to the PLC.
Note:
If the PLC Setup area is either written to the PLC or to the IO Table area the PLC may
need to be powered down and powered up in order for settings take effect. If the
settings need to be changed without switching off the PLC, write the PLC Setup data
first, then either generate or write the IO Table. Refer to
Chapter 4 - PLC Setup
Component.
Comparing an IO Table
The Registered IO Table can be compared with the CX-Server IO Table and displays any differences. This
option is helpful to confirm that a table that has been set up in CX-Server and has been transferred to the PLC,
agrees with how the hardware is set up. Use the following procedure to compare a Registered IO Table with
the CX-Server IO Table.
1, 2, 3…
1. Ensure the PLC is online before activating the IO Table component.
2. Select
Compare with PLC
from the
Options
menu.
Any differences (if any) are displayed in the IO Table component.
