TB bits are used in the following cases.
Note In the following cases, there are either no LD instructions after the branch points, or any LD instructions
Timer Area
The 256 timer numbers (T0000 to T0255) are shared by the TIM, TIMH(015), and TMHH(540) instructions.
Timer Completion Flags and present values (PVs) for these instructions are accessed with the timer numbers.
When a timer number is used in an operand that requires bit data (e.g., in LD, AND, or OR instructions), the
timer number accesses the Completion Flag of the timer. When a timer number is used in an operand that
requires word data (e.g., in MOV(021) or CMP(020) instructions), the timer number accesses the PV of the
timer. Timer Completion Flags can be used as often as necessary as normally open and normally closed con-
ditions and the values of timer PVs can be read as normal word data.
Timer Completion Flags can be force-set and force-reset.
Timer PVs cannot be force-set or force-reset, although the PVs can be refreshed indirectly by force-setting/
resetting the Completion Flag.
There are no restrictions in the order of using timer numbers or in the number of NC or NO conditions that can
be programmed. Timer PVs can be read as word data and used in programming.
Note It is not recommended to use the same timer number in two timer instructions because the timers will not
I/O Memory
• Each TR bit can be used only once in one program section.
• The status of TR bits cannot be changed from the CX-Programmer.
• When there are two outputs with different LD instructions after the last branch point:
• When there is no LD instruction on the lower rung after a branch point:
are on the bottom rung. TR bits are not required in these types of branches.
operate correctly if they are timing simultaneously. (If two or more timer instructions use the same timer
number, an error will be generated during the program check, but the timers will operate as long as the
instructions are not executed in the same cycle.)
