System Bit - Read/Write Tags (SBRW)

The following System Bit - Read/Write Tags are included in the Productivity Suite Programming Software. The Table provided below contains all the System Bit - Read/Write Tags organized by their System ID.

You may also view All the System Tags organized by their Purpose by selecting any of the following buttons.

CPU Tag Name	Type	System ID	Description	Update Interval
Initiate_New_Time	Bit	SBRW-001001	Bit to have CPU update the RTC, Times Only	1sec.
Initiate_New_Date		SBRW-001002	Bit to have CPU update the RTC, Dates Only.
Refresh Critical Error Log		SBRW-001003	Refresh the Critical Error Log.
Refresh Non-Critical Error Log		SBRW-001004	Refresh the Non-Critical Error Log.
Identify Module Request bit		SBRW-001005	Enable this Bit to have CPU query the Requested GBS Module Name.
Portable Memory Device Eject		SBRW-001006	On to eject portable storage device, "Portable Memory Device Ready" is off when ready to eject. Note: The portable memory device must be removed and reinserted to reactivate the writing device. Note: Should be used before removing a device to ensure all data is written to the drive prior to removal.	Event Based Note: System will reset to a low state when eject is completed.

Below is an example using a discrete bit to trigger the Portable Memory Device Eject system bit. Use an edge-triggered contact to SET the Portable Memory Device Eject bit. Once the SET goes high, the Portable Memory Device Ready bit will go low and the Portable Memory Device Eject bit will reset itself. RST instruction is not required.
