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 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 Controller Section can be set so that user-defined FAL
errors are not stored in the error log.
Provided on all models.
Accuracy: Ambient temperature
25°C
Note The accuracy will vary with the temperature.
Note Used to store the time when power is turned ON and
when errors occur.
2 ms
0 ms (fixed)
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 NSJ Controller 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.
FINS commands can be sent to a computer connected via
the Host Link System by executing Network Communications
Instructions from the Controller Section.
Host Link communications can be used for remote program-
ming and remote monitoring through a Controller Link Sys-
tem or Ethernet network.
Host Link communications can be used for remote program-
ming and remote monitoring from devices on networks up to
eight levels away (Controller Link Network or Ethernet Net-
work).
I/O comments can be stored as symbol table files in the
Memory Card in the Controller Section, EM file memory, or
comment memory (see note).
