Auxiliary Area (A)
Section 4-7
Instead, use a configuration like the one shown below.
There are no restrictions in the order of using bit address or in the number of
N.C. or N.O. conditions that can be programmed.
4-7
Auxiliary Area (A)
The Auxiliary Area contains 960 words with addresses ranging from A0 to
A959). These words are preassigned as flags and control bits to monitor and
control operation.
A0 through A447 are read-only, but A448 through A959 can be read or written
from the program or the CX-Programmer.
Refer to
Appendix C Auxiliary Area Allocations by Function
and
Appendix D
Auxiliary Area Allocations by Address
for Auxiliary Area functions.
Forcing Bit Status
Read/write bits in the Auxiliary Area cannot be force-set and force-reset con-
tinuously.
4-8
TR (Temporary Relay) Area
The TR Area contains 16 bits with addresses ranging from TR0 to TR15.
These temporarily store the ON/OFF status of an instruction block for branch-
ing and are used only with mnemonics. TR bits are useful when there are sev-
eral output branches and interlocks cannot be used.
The TR bits can be used as many times as required and in any order required
as long as the same TR bit is not used twice in the same instruction block.
TR bits can be used only with the OUT and LD instructions. OUT instructions
(OUT TR0 to OUT TR15) store the ON OFF status of a branch point and LD
instructions recall the stored ON OFF status of the branch point.
Forcing Bit Status
TR bits cannot be changed from the CX-Programmer.
Examples
In this example, a TR bit is used when two outputs have been directly con-
nected to a branch point.
