Most of the plug-in modules have defined events that are logged in the Module Event queue. For module-specific event definitions, see Plug-In Module Event Register Information.
Once a bit is set, it remains set until cleared by reading the event register or the *CLS (clear status) command.
Return Format
The command reads the event register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register. For example, if bit 1 (decimal value = 2) and bit 8 (decimal value = 256) are set, this command will return "+258".
Example
The following command reads the event register (bit 7 is set).
STAT:MOD:EVEN?
Typical Response: +128
