Item
Specifications
EM Area
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.
Data Registers
DR0 to DR15: Store offset values for indirect addressing. One register is 16 bits (1 word).
Index Registers
IR0 to IR15: Store PLC memory addresses for indirect addressing. One register is 32 bits (2 words).
Task Flag Area
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.
Trace Memory
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.
File Memory
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).
Parallel Processing
Modes
Program execution and peripheral servicing can be performed simultaneously.
Battery-free operation The user program and the system’s parameters are backed up automatically in flash memory, which is standard equipment.
Constant cycle time Possible (1 to 32,000 ms) (Unit: 1 ms)
Cycle time monitoring Possible (Unit stops operating if the cycle is too long): 10 to 40,000 ms (Unit: 10 ms)
I/O refreshing
Cyclic refreshing, immediate refreshing, refreshing with I/O REFRESH instruction
I/O memory holding
when changing
operating modes
Possible (Depends on the ON/OFF status of the IOM Hold Bit in the Auxiliary Area.)
Load OFF
All outputs on Output Units can be turned OFF.
Input response time
setting
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).
Startup mode setting Supported.
Automatically reading programs (autoboot) from the Memory Card when the power is turned ON.
Memory Card
functions
Format in which data is stored in Memory Card
User program: Program file format
PLC Setup and other parameters: Data file format (binary format)
I/O memory: Data file format (binary format), text format, or CSV format
Functions for which Memory Card read/write is
supported
User program instructions, Programming Devices (including Programming Consoles),
Host Link computers
Filing
Memory Card data and the EM (Extended Data Memory) Area can be handled as files.
Debugging
Control set/reset, differential monitoring, data tracing (scheduled, each cycle, or when instruction is executed), storing location generating
error when a program error occurs
Online editing
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.)
Program protection
Overwrite protection: Set using DIP switch.
Copy protection: Password set using Programming Device.
Error check
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.
Functions
Error log
Serial
communications
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
*3, and Modbus-RTU Slave *5
Clock
Provided on all models.
Note: Used to store the time when power is turned ON and when errors occur.
Power OFF detection
time
10 to 25 ms (not fixed)
Power OFF detection
delay time
0 to 10 ms (user-defined, default: 0 ms)
Memory retention
during power
interruptions
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.
Sending commands to FINS commands can be sent to a computer connected via the Host Link System by executing Network Communications Instructions from
a Host Link computer the PLC.
Remote programming Host Link communications can be used for remote programming and remote monitoring through a Controller Link System or Ethernet
and monitoring
network.
8-level
communications *2
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.)
Storing comments in
CPU Unit
I/O comments can be stored in the CPU Unit in Memory Cards *1 or EM file memory.
Program check
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.
Control output signals
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.
Battery service life
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
Self-diagnostics
CPU errors (watchdog timer), I/O verification errors, I/O bus errors, memory errors, and battery errors.
Other functions
Words in the Auxiliary Area store the number of power interruptions, time of the last power interruption, and total power ON time.
*1. CPU Units with unit version 3.0 or later only.
*2. 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.
*4. Use a replacement battery that was manufactured within the last two years.
