PON (Power ON) bit
The PON bit (bit 7) in the event status register is set whenever the PAT is turned on.
The most common use for the PON is to generate an SRQ at power-on keeping track
of unexpected loss of power or power line failure. To do this, follow the steps shown
below.
1
Set *PSC (Po w er-on Stat u s Clear) to 0 (or OFF).
Enable the backup function of the event status enable register and service request
enable register (*PSC 0).
2
Set the PO N bit (bit 7) of the event stat u s enable register.
Permit the transmission of a power-on event to the upper layer (*ESE 128).
3
Set the ESB bit (bit 5) of the stat u s byte enable register.
Permit the generation of an SRQ caused by a standard event (*SRE 32).
*PSC 0;*ESE 128;*SRE 32
When using the RS232C interface, the PON bit cannot be assigned to the service
request, because SRQs are not generated.
Though the SRQ feature itself is provided by the USBTMC Interrupt-IN endpoint
on the USB interface or LAN interface, a Connection Lost error in the VISA I/O
session occurs immediately before the power-on event. It may be difficult to handle
PON events when using the USB interface.
