E Error And Arithmetic Flag Operation - Omron SYSMAC mini SP10 Operation Manual

The following table shows the instructions that affect the ER, CY, GT, LT and EQ flags. In general, ER indi-
cates that operand data is not within requirements. CY indicates arithmetic or data shift results. GT indicates
that a compared value is larger than some standard, LT that it is smaller, and EQ, that it is the same. EQ also
indicates a result of zero for arithmetic operations. Refer to Section 3 Instruction Set for details.
Vertical arrows in the table indicate the flags that are turned ON and OFF according to the result of the in-
struction.
Although timer and counter instructions are executed when ER is ON, instructions with a vertical arrow under
the ER column are not executed if ER is ON. All of the other flags in the following table will also not operate
when ER is ON.
