Other functions
*1.
CPU Units with unit version 3.0 or later only.

CPU Units with unit version 2.0 or later only. (Communications across three network layers is supported for Pre-Ver. 2.0 CPU Units.)
*3.
CPU Units with unit version 3.0 or later only or Serial Communications Board/Unit with unit version 1.2 or later only.

*5.
Serial Communications Board/Unit with unit version 1.3 or later only.
32K words per bank, 13 banks max.: E0_00000 to EC_32767 max. (Varies by CPU Unit model.)
Used as a general-purpose data area for reading and writing data in word units (16 bits). Words in the EM Area maintain their status when
the PLC is turned OFF or the operating mode is changed.
The EM Area is divided into banks, and the addresses can be set by either of the following methods.
Changing the current bank using the EMBC(281) instruction and setting addresses for the current bank. Setting bank numbers and
addresses directly.
EM data can be stored in files by specifying the number of the first bank.
DR0 to DR15: Store offset values for indirect addressing. One register is 16 bits (1 word).
IR0 to IR15: Store PLC memory addresses for indirect addressing. One register is 32 bits (2 words).
32 (TK0000 to TK0031): Task Flags are read-only flags that are ON when the corresponding cyclic task is executable and OFF when the
corresponding task is not executable or in standby status.
4,000 words (The maximum amount of data that can be traced in a data trace is 500 samples for 31 bits and 6 words.
Memory Cards: Compact flash memory cards can be used (MS-DOS format).
EM file memory: Part of the EM Area can be converted to file memory (MS-DOS format).
Program execution and peripheral servicing can be performed simultaneously.
The user program and the system's parameters are backed up automatically in flash memory, which is standard equipment.
Possible (1 to 32,000 ms) (Unit: 1 ms)
Possible (Unit stops operating if the cycle is too long): 10 to 40,000 ms (Unit: 10 ms)
Cyclic refreshing, immediate refreshing, refreshing with I/O REFRESH instruction
Possible (Depends on the ON/OFF status of the IOM Hold Bit in the Auxiliary Area.)
All outputs on Output Units can be turned OFF.
Time constants can be set for inputs from Basic I/O Units.
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 (CS1 Basic I/O Units only).
Supported.
Automatically reading programs (autoboot) from the Memory Card when the power is turned ON.
Format in which data is stored in Memory Card
Functions for which Memory Card read/write is
supported
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 Unit is in MONITOR or PROGRAM mode.
(This function is not available for block programming areas.)
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.
Up to 20 errors are stored in the error log. Information includes the error code, error details, and the time the error occurred.
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, and Serial Gateway *3
Serial communications board (order separately): protocol macros, Host Links, no-protocol communications *3, NT Links, Serial Gateway
Provided on all models.
Note: Used to store the time when power is turned ON and when errors occur.
10 to 25 ms (not fixed)
0 to 10 ms (user-defined, default: 0 ms)
Held Areas: Holding bits, contents of Data Memory and Extended Data Memory, and status of the counter Completion Flags and present
values.
Note: If the IOM Hold Bit in the Auxiliary Area is turned ON, and the PLC Setup is set to maintain the IOM Hold Bit status when power to
the PLC is turned ON, the contents of the CIO Area, the Work Area, part of the Auxiliary Area, timer Completion Flags and PVs, Index
Registers, and the Data Registers will be saved.
FINS commands can be sent to a computer connected via the Host Link System by executing Network Communications Instructions from
the PLC.
Host Link communications can be used for remote programming and remote monitoring through a Controller Link System or Ethernet
network.
Remote programming and monitoring across up to eight network layers (Controller Link or Ethernet) by using Host Link. (They are possible
between different types of networks.)
I/O comments can be stored in the CPU Unit in Memory Cards *1 or EM file memory.
Program checks are performed at the beginning of operation for items such as no END instruction and instruction errors.
Programming Devices (except for the Programming Consoles) can also be used to check programs.
RUN output: The internal contacts will be ON (closed) while the CPU Unit is operating in RUN mode or MONITOR mode.
These terminals are provided only on C200HW-PA204R, C200HW-PA209R, and CS1D-PA207R Power Supply Units.
The battery life is 5 years at an ambient temperature of 25°C, although the lifetime can be as short as 1.1 years under adverse temperature
and power conditions. (Battery Set: CS1W-BAT01) *3 *4
CPU errors (watchdog timer), I/O verification errors, I/O bus errors, memory errors, and battery errors.
Words in the Auxiliary Area store the number of power interruptions, time of the last power interruption, and total power ON time.
