The data above are collected with compressed data function of Datalink. The tag is an amps of a motor. As you see above, the motor stops at 7:08:45 and starts back up 8:30:25. But since we set 'step attribute' off, there is an interpolated line between these two dots. Why does not PI record the prior event to 8:30:25?
Below are the setting of the tag in SMT:
typical value:100 zeo:0 span:200
Scan: On Archiving: On Step: Off Shutdown: On Compression: On
Exception Dev: 1 Eng. Units Compression Dev: 2 Eng. Units
ExpMin: 0 ExpMax:10mins CompMin: 0 CompMax: 8hrs
Thanks
