| The Trend graph object continuously monitors specific tags in the EZ series Touch panel and displays their value as they change over time. Up to 6 tags can be monitored per Trend Graph and up to 100 Trend Graphs can be programmed. This object actually acts like a VCR and using Arrow keys you could scroll forward or backwards along the graph. Trend Graph store up to 999 data points can can be set to increments of seconds, minutes, hours or even days. |
