USING THE ERROR AND STATUS REGISTERS
The SCPI error and status registers report many conditions, statuses and events into short
numeric codes. Momentary events may be latched so the remote computer can read about
them at a later time. A "fan out" architecture is used to summarize all the data into one
Status Byte register
The Genesys™ power supply, with the LAN option, does not support the service request
feature defined in the Status Byte register
There are three types of registers. Data, as in a bit is set high or low, flows top to bottom in
the following list. See Figure 6 for the diagram
Condition Registers: contain bits that are set when a condition or error occurs. The
bits are only cleared when the condition or error is cleared. The contents may be read
but not changed
Enable Registers: individual bits may be set to allow the status and errors to be
latched for reading even after the status or error condition has cleared. The power-up
default is all zeroes, that is, no latching occurs
Event Registers: bits that are set when an event or error occurs. The bits are
cleared when the contents of the register are read or when a clear status command is
sent
7.8.4. Clear Status
This command resets the error, status and message registers in the LAN board. No power
supply settings are changed
The *CLS command will:
− Erase any response message in the output queue
− Erase any errors in the SYSTEM:ERROR queue
− Reset all event registers to zeroes
− Will not change any Enable or Condition register bits
