Status, Error, And Srq Registers - TDK-Lambda Genesys User Manual

8.11. Status, Error, and SRQ Registers

8.11.1. General Description
This Section describes the structure and operation of the six status, error, and SRQ
registers. The registers can be set or read via the RS-232/RS-485 commands.
Refer to Fig. 8-7 for the Status and Error Registers Diagram.
NOTE: these registers operate in a way that is similar to the IEEE-488 and SCPI
registers (as used by the Genesys™ with the "-IEMD" option), but the structure and
command set is different.

"Inn" and CR
One SRQ when SEVE goes
from all zeroes to any bit set.
Setting more SEVE bits does
not cause more SRQs.
Positive Logic:
0 = No Event
1 = Event Occured
