Note
- The entry condition of
11OFF while the instruction is being run, the instruction will end in an incomplete condition. Once this condition occurs, a "communication jam" occurs when an instruction execution is attempted the next time, and the instruction will not run properly. To restore the condition, power OFF the PC, and turn it ON again.
-If the entry condition turns OFF, due to an instantaneous power failure, turn the entry condition to "latched relay" as a remedy. If, however, any power loss occurs while an instruction is being run using "latched relay," turning the power ON again will cause
