Specification
Up to 20 errors are stored in the error log. Information
includes the error code, error details, and the time the error
occurred.
A CS1-H CPU Unit can be set so that user-defined FAL
errors are not stored in the error log.
Programming Console) connections, Host Links, NT Links
Built-in RS-232C port: Programming Device (excluding
Programming Console) connections, Host Links, no-proto-
col 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
(accuracy varies with the temperature)
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 Comple-
tion 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 Flag and PVs,
Index Registers, and the Data Registers will be
saved for up to 20 days.
FINS commands can be sent to a computer connected via
the Host Link System by executing Network Communica-
tions Instructions from the PLC.
Host Link communications can be used for remote pro-
gramming and remote monitoring through a Controller Link
System or Ethernet network.
Remote programming and monitoring using the Support
Software, as well as FINS message communications, can
be conducted across network layers, including other types
of network.
Pre-Ver. 2.0: Three layers
Version 2.0 or later: Eight layers for Controller Link and
Ethernet (see note). Three layers for
DeviceNet and SYSMAC LINK.
Note To construct a network of eight layers, it is necessary
to use the CX-Integrator or CX-Programmer (version
4.0 or higher) to set routing tables.
I/O comments can be stored as symbol table files in the
Memory Card, EM file memory, or comment memory (see
note).
Note Comment memory is supported for CS/CJ-series
CPU Units with unit version 3.0 or later only.
