Detailed I/O table error information is stored in A261 whenever the I/O tables
cannot be created for any reason.
It's possible to confirm if the first rack word has been specified for the system on
the Programming Console display.
The first rack word is specified from the CX-Programmer, making it previously
impossible to confirm the setting from the Programming Console.

CPM2A-BAT01
Starting or not starting (standby) the CPU Unit in MONITOR or RUN mode even
if a Unit has not completed startup processing can be specified in the PLC
Setup.

CX-Programmer
Ver. 7.1 or higher).
Supported (enabling standard deviation calculations).
Supported.
Floating point can be converted to ASCII for display on PTs.
ASCII text strings from measurement devices can be converted to floating-point
decimal for use in calculations.
Supported (enabling high-precision positioning).
Data processing can be performed normally or in the background (specified for
each instruction).
(Using time slices to process instruction over several cycles reduces the effect
of these instructions on the cycle time.).
Supported.
Effective for tracking workpieces on conveyor lines.
