Task Number when Program
Stopped A294 This word contains the task number of the task that was
being executed when program execution was stopped
because of a program error. Read-only
Maximum Interrupt Task
Processing Time A440 Contains the Maximum Interrupt Task Processing Time
in units of 0.1 ms as hexadecimal data. Read-only
Interrupt Task with Max.
Processing Time A441 Contains the task number of the interrupt task with the
maximum processing time. Hexadecimal values 8000 to
80FF correspond to task numbers 00 to FF. Bit 15 is
turned ON when an interrupt has occurred. Read-only
IR/DR Operation between
Tasks A99.14 ON when index and data registers are shared between
all tasks.
OFF: Independent
ON: Shared (default) Read-only
Name Address Description Access Updated
Online Editing Wait Flag A201.10 ON when an online editing process is waiting. Read-only
Online Editing Processing
Flag A201.11 ON when an online editing process is being executed. Read-only
Online Editing Disable Bit
Validator A527.00 to
A527.07 The Online Editing Disable Bit (A527.09) is valid only
when this byte contains 5A. Read/write
Online Editing Disable Bit A527.09 Turn this bit ON to disable online editing. The setting of
this bit is valid only when A527.00 to A527.07 have been
set to 5A. Read/write
Name Address Description Access Updated
Output OFF Bit A500.15 Turn this bit ON to turn OFF all outputs from the CPU
Unit, CPM1A Units, and Special I/O Units. Read/write
Name Address Description Access Updated
Differentiate Monitor Com-
pleted Flag A508.09 ON when the differentiate monitor condition has been
established during execution of differentiation monitoring. Read/write
Name Address Description Access Updated
Sampling Start Bit A508.15 When a data trace is started by turning this bit ON from
the CX-Programmer, the PLC will begin storing data in
Trace Memory by one of the three following methods:
Data is sampled at regular intervals (10 to 2,550 ms).
Data is sampled when TRSM(045) is executed in the
program.
Data is sampled at the end of every cycle. Read/write
Trace Start Bit A508.14 Turn this bit ON to establish the trigger condition. The off-
set indicated by the delay value (positive or negative)
determines which data samples are valid. Read/write
Trace Busy Flag A508.13 ON when the Sampling Start Bit (A508.15) is turned ON.
OFF when the trace is completed. Read/write
Trace Completed Flag A508.12 ON when sampling of a region of trace memory has
been completed during execution of a trace. Read/write
Trace Trigger Monitor Flag A508.11 ON when a trigger condition is established by the Trace
Start Bit (A508.14). OFF when the next data trace is
started by the Sampling Start Bit (A508.15). Read/write
