Keep Designation for Internal Relays, Shift Registers, Counters, and Data Registers
The statuses of internal relays and shift register bits are usually cleared at startup. It is also possible to designate all or a block of
consecutive internal relays or shift register bits as “keep” types. Counter current values and data register values are usually
maintained at powerup. It is also possible to designate all or a block of consecutive counters and data registers as “clear” types.
When the SmartAXIS is stopped, these statuses and values are maintained. When the SmartAXIS is reset by turning on a
designated reset input, these statues and values are cleared despite the settings in the Configure Keep/Clear Settings dialog box
shown below. The keep/clear settings in this dialog box are not maintained when restarting the SmartAXIS.
Since these settings relate to the user program, the user program must be downloaded to the SmartAXIS after changing any of
these settings.
