Status Reporting 93
RI (Remote Inhibit)
Whenever a remote inhibit signal is received at the digital port (see appendix C - Digital Port Functions), the Agilent SAS
will receive an RI event at the Questionable Status register. By programming the status subsystem, you may use RI to
generate a service request (SRQ) to the controller and/or to create a DFI output at the digital port. By using RI/DFI in this
way, you can chain the power supplies to create a serial shutdown in response to the INH input.
To enable the OV, OC, OT, and the RI conditions to generate an FLT signal, program the Questionable Status register as
follows: STAT:QUES:ENAB 531
Using Device Clear
You can send a device clear at any time to abort a SCPI command that may be hanging up the GPIB interface. The status
registers, the error queue, and all configuration states are left unchanged when a device clear message is received. Device
clear performs the following actions:
The input and output buffers of the dc source are cleared.
The dc source is prepared to accept a new command string.
The following statement shows how to send a device clear over the GPIB interface using Agilent BASIC:
