Unexpected value

If a PI point is receiving a value that is unexpected, set the point's Location5 attribute to 3. Then, PI SNMP will print information to the message log regarding the value it received from the SNMP device and the value that it sent to the UniInt interface template. For example,

25-Oct-04 13:23:00
PI SNMP- 1> pt (localhost_sysUptime_abs), rx data type: not explicitly checked for
25-Oct-04 13:23:00
PI SNMP- 1> val.integer is 1598036
25-Oct-04 13:23:00
PI SNMP- 1> pt (localhost_sysUptime_abs), t=1061583780.03 drval=0.185 ival=0 istat=0 returned to UniInt

The above indicates that the interface:

• received a value of 1598036 from the SNMP device

• sent a value of 0.185 to the UniInt interface template

(The point's conversion attribute is 0.00000011574, which is 0.185 divided by 1598036.)

It may take up to 2 minutes for the interface to be aware of the change to Location5. The interface will have to perform the scan associated with the point before a new value is recorded.

Be sure to set Location5 back to 0 afterwards. Otherwise, the interface will continue to write the debug messages to the log.
