Start screen Saver

The backlight turns OFF when the Start screen Save tag changes from OFF to ON. The panel backlight will turn ON again:

• When the panel touchscreen is touched
• When the screen is clicked in a Remote Access session
• When an Alarm Action in the Event Manager occurs (only when the Display setting of the Alarm Action is checked)
• When there is a screen Change by the PLC
• When an Error such as a Communication Error occurs

There is not a definite answer for this because it depends upon several factors. C-more updates each Object as the Data is received from the PLC in communication packets. So there really isn't a screen Update Time. There could be one communication packet for a screen or there may be many based upon how efficiently the PLC Addresses were chosen for each Object.

Other factors that affect Update Times are:

• The Poll Rate set for the particular protocol
• This is the time between each packet and is set by the programmer. It is used to reduce network traffic when many devices are on one network
• The network communication settings such as Baud Rate
• The network type such as Serial or Ethernet
• The number of PLC Nodes
• Background transactions such as Trend Graphs, Data Logging, Event Manager, FTP and Webserver (Secure HTTPs) transactions.
• Types of Objects on the screen (i.e., Animation, Transparency, Blinking and Overlapping Objects) all increase the screen Redraw Time
