Changing the Timer/Counter PV Refresh Mode Section 6-4
BCD Mode/Binary Mode Data Display
Note When using the CX-Programmer in either BCD or binary mode, if the numeri-
cal value is input without including the input/display symbol # or & indicating
the constant, (e.g., TIM 0000 0010), the timer/counter set value will be input
as an address (e.g., the value in CIO word 0010 will be used as the set value).
6-4-5 Restrictions
• BCD mode and binary mode cannot be used together in the same CPU
Unit.
• When the Programming Console is used to create a new user program, or
to clear memory, the timer/counter PV refresh mode is fixed in BCD
mode.
• When CX-Programmer Ver. 3.0 is used to place the CPU Unit online, the
set value that is stored in the CPU Unit’s user memory for the timer/
counter PV refresh mode will be automatically used. If the CPU setting is
different from the setting for the CX-Programmer project, an error will
occur, and the online connection will not be possible. The following mes-
sage will be displayed.
Select whether to change the CPU Unit setting to that for the CX-Programmer
project or change the CX-Programmer project property setting to that for the
CPU Unit.
• CX-Programmer Ver. 2.1 or earlier cannot read user programs in the CPU
Unit that are set using binary mode, but can read those set using BCD
mode.
