STA Command Row and Column Definitions
FID FID is the firmware identifier string. It identifies the firmware revision.
CID CID is the firmware checksum identifier.
OS OS = Offset; displays measured dc offset voltages in millivolts for the current and
voltage channels. The MOF (master) status is the dc offset in the A/D circuit when a
grounded input is selected.
PS PS = Power Supply; displays power supply voltages in Vdc for the power supply
outputs.
TEMP Displays the internal relay temperature in degrees Celsius.
RAM, ROM, CR_RAM (critical RAM), and EEPROM
These tests verify the relay memory components. The columns display OK if memory
is functioning properly; the columns display FAIL if the memory area has failed.
A/D Analog to Digital convert status.
IO_BRD Extra I/O board status (model 0351x1 only - see Table 1.1 and Figure 2.4 and 2.17).
W (Warning) or F (Failure) is appended to the values to indicate an out-of-tolerance condition.
The relay latches all self-test warnings and failures in order to capture transient out-of-tolerance
conditions. To reset the self-test statuses, use the STA C command from Access Level 2:
=>>STA C <ENTER>
The relay responds:
Reboot the relay and clear status
