Duplex Settings - Omron CX-PROGRAMMER V9 Operation Manual

OMRON
If Peripheral Service is chosen, editing Peripheral Service Execution Time is possible, and the system sets the
default to 0.1. See also Instruction Processing (Peripheral Service Execution Time).
Specifying Asynchronous will disable the same options as Not Specified, and set the Execution mode to
Asynchronous processing. Synchronous likewise sets the Execution Mode to Synchronous processing.
Peripheral Service Mode
Instruction Execution Time - A value within and including the range of 5 to 255 or 0 can be entered as a valid
setting.
Peripheral Service Execution Time - A value within and including 0.1 to 25.5 can be entered as a valid setting. For
more information on when this option is available, see Sync/Async Comms, Execution Mode, above.
Target Unit (1, 2, 3, 4, 5) and SIOU - The default for this setting is Not Specified. There are five possible options
for this setting. After Not Specified, the next option is CPU SIOU. If this option is selected, the SIOU number
should be entered in the box to the right marked 'SIOU'. The next option is SIOU, and likewise with the CPU
SIOU option, the SIOU number should be entered in the box to the right marked 'SIOU'. The three remaining
options allow either the Inner Board, Host Link Port or Peripheral Port to be set as the 'Target Unit'.
Set time to all events
Set time to all events (default 4%) - By ticking the checkbox, the default as stated above will be set. If the
checkbox is not ticked, then a value between 0 and 255 inclusive can be entered, making a maximum setting of
25.5 (255 *0.1). This option is found in the Timings tab for all other CS/CJ-series PLCs.

Duplex Settings

The Duplex Setting tab is activated by selecting the Duplex Settings option from the PLC Settings Options menu.
With this option checked, use the Tabs scroll buttons to scroll to the right and click on the Duplex Settings tab to
bring it to the front. The options in this dialog can now be set to provide the appropriate communications setup
within the selected Communications Units. The dialog is divided into five sections as follows:
Note: The Duplex Setting tab is available for CS1H-H 65 & 67 PLCs but is only applicable to the CS1D series
PLCs.
Operation Settings
Run under Duplex Initial – This option should be selected if it is required to run two Units in parallel with Duplex
Initial execution. Note that this setting only takes effect at startup or at the start of an operation. It cannot be
changed during an operation.
Return Automatically – Select this option when it is required to execute a process that returns to Duplex Operation
automatically.
Communications Unit Duplex Setting
From the list of Communications Units select those that are to be run in duplex mode. If more than one Unit is set
to duplex mode the options selected will be applied to each Unit. It is not possible to set different options for
different Communications Units. To execute the Communication Duplex operation an IO table must be created or
transferred. Note that this setting only takes effect at startup or at the start of an operation. It cannot be changed
during an operation.
Hot Swap
Allow Plural Units - Selecting this option enables Units operating in Parallel or Duplex mode to be replaced while
online. The Units, which can be exchanged while online are, Basic IO Units, SIOUs, and CPU SIOUs of the
CS-Series PLCs. Note that this option can be selected while online.
