ASCII Commands
Parameter n specifies the event report number. Use the HIS command to deter-
mine the event report number of the event you want to display. If n is not speci-
fied, the device displays Event Report 1.
CHISTORY Command
(Compressed History)
The device generates the Compressed ASCII history in response to the CHI com-
mand, as shown in Table 7.15.
Parameter x is the number of events you want displayed. The device shows fewer
than x events if x is less than the number of stored events. If x is greater than the
number of stored events, the device displays all of the stored events.
CMETER Command
(Compressed METER)
The device generates the Compressed ASCII meter of fundamental, analog input,
math variable, remote analog, and signal profile data in response to the CME x
(x = FUN, ANA, MAT, REM) command, as shown in Table 7.16.
NOTE: Information displayed in
parenthesis is optional.
COMMUNICATIONS
Command
The COM x command displays communications statistics for the MIRRORED
B
ITS communications channels. For more information on MIRRORED BITS com-
munications, see Appendix G: Mirrored Bits Communications. The summary
report includes information on the failure of ROKA or ROKB. The Last error
field displays the reason for the most recent channel error, even if the channel
was already failed. We define failure reasons as one of the following error types:
➤ Device disabled
➤ Framing error
➤ Parity error
➤ Overrun
➤ Re-sync
➤ Data error
