1 to 32,000 ms (Unit: 1 ms)
Possible (Module stops operating if the cycle is too long): 10 to 40,000 ms (Unit: 10 ms)
Data links for Controller Link Modules and SYSMAC LINK Modules, remote I/O for DeviceNet Modules,
and other special refreshing for CPU Bus Units is performed at the I/O refresh period and when the CPU
Bus Unit I/O REFRESH (DLNK(226)) instruction is executed.
Depends on the ON/OFF status of the IOM Hold Bit in the Auxiliary Area.
All outputs on Output Modules can be turned OFF when the CPU is operating in RUN, MONITOR, or
PROGRAM mode.
Time constants can be set for inputs from Basic I/O Modules. The time constant can be increased to
reduce the influence of noise and chattering or it can be decreased to detect shorter pulses on the
inputs.
Supported.
The CPU will start in RUN mode if the PLC Setup is set to use the Programming Console mode (default)
and a Programming Console is not connected.
The user program and Parameter Area data (e.g., PLC Setup) are always backed up automatically in
flash memory.
Automatically reading programs (autoboot) from Supported.

ON.
Program replacement during PLC operation
Supported.
Format in which data is stored in Memory Card User program:Program file format
PLC Setup and other parameters: Data file format
I/O memory: Data file format (binary format), text format,
or CSV format (except pre-version-1 CS1 CPUs)

Functions for which Memory Card read/write is
supported
User program instructions, Programming Devices
(including Programming Consoles), Host Link
computers, AR Area control bits, simple backup
operation
Memory Card data and the EM (Extended Data Memory) Area can be handled as files.
Control set/reset, differential monitoring, data tracing (scheduled, each cycle, or when instruction is
executed), storing location generating error when a program error occurs
User programs can be overwritten in program--block units when the CPU is in MONITOR or PROGRAM
mode. This function is not available for block programming areas. With the CX--Programmer, more than
one program block can be edited at the same time.
Overwrite protection: Set using DIP switch.
Copy protection: Password set using Programming Device.
User--defined errors (i.e., user can define fatal errors and non--fatal errors)
The FPD(269) instruction can be used to check the execution time and logic of each programming block.
FAL and FALS instructions can be used with the CS1-H CPUs to simulate errors.
Up to 20 errors are stored in the error log. Information includes the error code, error details, and the time
the error occurred.
The CPU can be set so that user--defined FAL errors are not stored in the error log.
Built-in peripheral port: Programming Device (including Programming Console) connections, Host Links,
NT Links
Built-in RS-232C port: Programming Device (excluding Programming Console) connections, Host Links,
no-protocol communications, NT Links
Serial Communications Board (sold separately): Protocol macros, Host Links, NT Links
Provided on all models. Accuracy: ± 30 s/mo. at 25°C

Note: a.) The accuracy varies with the temperature;
b.) Used to store the time when power is turned ON and when errors occur.

2 to 5 ms (DC power supply)
0 to 10 ms (user-defined, default: 0 ms)
