CPU Overview
CS1 CPU Specifications
J Function Specifications
Item
Specification
Constant cycle time
1 to 32,000 ms (Unit: 1 ms)
Cycle time monitoring
Possible (Module stops operating if cycle is too long): 1 to 40,000 ms (Unit: 10 ms)
I/O refreshing
Cyclic refreshing, immediate refreshing, refreshing by IORF(097).
I/O memory holding when
changing operating modes
Possible (Depends on ON/OFF status of IOM Hold Bit in Auxiliary Area.)
Load OFF
All outputs on Output Modules can be turned OFF.
Input time constant setting
Time constants can be set for inputs from CS1 Basic I/O Modules. The time constant can be
increased to reduce influence of noise and chattering or it can be decreased to detect shorter pulses
on inputs. (CS1 Basic I/O Modules only)
Mode setting at power-up
Possible
Memory Card functions
Automatic reading programs from Memory Card (autoboot).
Memory Card Storage Data User program: Program file format (binary)
PC System Setup: Data file format (binary)
I/O Memory: Data file format (binary), text format, CSV format
Memory Card Read/Write
User program instructions, Peripheral Devices (such as Programming Console), Host Link computer.
Filing
Memory Card data and EM (Extended Data Memory) Area can be handled as files.
Debugging
Force-set/reset, differential monitoring, data tracing (scheduled, each cycle, or when instruction is
executed), instruction error tracing.
Online editing
One or more program blocks in user programs can be overwritten when CPU is in PROGRAM or
MONITOR mode. This function is not available for block programming areas.
Program protection
Overwrite protection: Set using DIP switch.
Copy protection: Password set using Peripheral 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 execution time and logic of each programming block.
Error log
Up to 20 errors are stored in error log. Information includes error code, error details, and time error
occurred.
Serial communications
Built-in peripheral port: Peripheral Device (including Programming Console), Host Links, NT Links
Built-in RS-232C port: Peripheral Device (excluding Programming Console), Host Links, no-protocol
communications, NT Links
Communications Board (sold separately): Protocol macros, Host Links, NT Links
Clock
Provided on all models.
Note: Used to store 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 protection
Held Areas: Holding bits, contents of Data Memory and Extended Data Memory, and status of
counter Completion Flags and present values.
Note: If IOM Hold Bit in Auxiliary Area is turned ON, and PC Setup is set to maintain IOM Hold Bit
status when power to PLC is turned ON, contents of CIO Area, Work Area, part of Auxiliary
Area, timer Completion Flag and PVs, Index Registers, and Data Registers will be saved.
