SET CARRY – STC(40)
Ladder Symbols
STC(40)
@STC(40)
When the execution condition is OFF, STC(40) is not executed.When the execu-
tion condition is ON, STC(40) turns ON CY (SR 25504).
Note Refer to Appendix C Error and Arithmetic Flag Operation for a table listing the
instructions that affect CY.

CLEAR CARRY – CLC(41)
Ladder Symbols
CLC(41)
@CLC(41)
When the execution condition is OFF, CLC(41) is not executed.When the execu-
tion condition is ON, CLC(41) turns OFF CY (SR 25504).
CLEAR CARRY is used to reset (turn OFF) CY (SR 25504) to “0”.
CY is automatically reset to “0” when END(01) is executed at the end of each
cycle.
Note Refer to Appendix C Error and Arithmetic Flag Operation for a table listing the
instructions that affect CY.

Description
When the execution condition is OFF, ADD(30) is not executed. When the exe-
cution condition is ON, ADD(30) adds the contents of Au, Ad, and CY, and places
the result in R. CY will be set if the result is greater than 9999.

Flags
ER:
Au and/or Ad is not BCD.
Indirectly addressed DM word is non-existent. (Content of
∗
DM word is
not BCD, or the DM area boundary has been exceeded.)
CY:
ON when there is a carry in the result.
EQ:
ON when the result is 0.
