7.8 STATUS, ERROR AND SRQ REGISTERS

7.8.1 General

This section describes the various status error and SRQ registers structure. The registers can be
read or set via the RS232/485 commands. When using the IEEE option, refer to the user manual
TM
for Genesys Power Supply IEEE Programming interface.
Refer to Fig.7-7 for the Status and Error Registers Diagram.

7.8.2 Conditional registers

The fault Condition Register and the Status Condition Register are read only registers that the user
may read to see the condition of the supply. Refer to table 7-8 for description of the Fault Condition
Register bits and Table 7-9 for the Status Condition register bits.

SRQ = "!nn",
nn = address
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
