8.1.6ANALOG LOOP DIAGNOSTICS

8.1.6.1TC Command (Total Counts)

This command gives totals of node failures and powerups on the analog loop. See the EC command to get values broken down to individual devices.

>>tc

Transmit echo reception fail count 5 Total reply fail count 191

Total device powerups 0

“Transmit echo reception fail count” indicates the number of times the MXP has been unable to receive its own transmission on the analog loop. This should normally increment only when the loop is subjected to abnormal events, e.g. shorts. This value is not cleared when the MXP powers up, it is only cleared by the RS command.

“Total reply fail count” increments when a device does not reply to a poll, but has not already been deemed to have failed. When a device is removed this value will increment by 12. This value is not cleared when the MXP powers up, it is only cleared by the RS command.

“Total device powerups” increments when a device powers up. This should normally increment by one for each device when the loop first powers up, and by one each time a detector is plugged into a base with the loop powered up. If it increments at other times it is indicative of a problem which requires investigation. This value is set to zero when the MXP powers up.

8.1.6.2EC Command (Error Counts)

This command gives total error counts as per the TC command, and then also gives the reply fail counts for individual devices, and an indication of whether each device is deemed to be in “scan fail”. These individual counts are not cleared when the MXP powers up, but are reset by the RS command.

This command is also useful to determine which points are configured and what their type is.
