Settings Other Than Those for Duplex Systems

Cases when settings must be changed
The input response time settings for Basic I/O Units must be changed in the
following cases:
• Chattering or noise occur in CS-series Basic I/O Units.
• Short pulse inputs are being received for intervals longer than the cycle
time.
Data in all regions of I/O Memory (including the CIO Area, Work Areas,
Timer Flags and PVs, Task Flags, Index Registers, and Data Registers)
must be retained when the PLC's power is turned ON.
The status of bits force-set or force-reset from a Programming Device
(including Programming Consoles) must be retained when the PLC's power
is turned on.
• You do not want the operating mode to be determined by the Programming
Console's mode switch setting at startup.
• You want the PLC to go into RUN mode or MONITOR mode and start oper-
ating immediately after startup.
• You want the operating mode to be other than PROGRAM mode when the
power is turned ON.
Disabling detection of low-battery errors when it is not required.
Detecting interrupt-task errors is not required.
Data files are required but a Memory Card cannot be used or the files are
written frequently. (Part of the EM Area will be used as file memory.)
5. This function is supported only by Duplex CPU Units with Unit Ver. 1.3 or
later.
6. As of October 2006, these settings can be selected with the Programming
Console only. The settings will be added to the CX-Programmer in the next
version upgrade. The settings will be added to CX-Programmer version 7.0
when its functions are expanded by auto-update.
When using CX-Programmer version 3.0 or higher, set the device type to
"CS1H-H" in the PLC Setup and select Duplex Settings from the Options
Menu on the PLC Settings Window to enable setting the PLC Setup for a
CS1D.
When using CX-Programmer version 4.0 or higher and the device type is set
to "CS1S-H" or "CS1D-S," is it not necessary to select Duplex Settings from
the Options Menu on the PLC Settings Window to enable setting the PLC
Setup for a CS1D.
The following table lists cases in which the PLC Setup must be changed for
aspects of operation not directly related to duplex operation.
