It is set correctly. I also have the Read Tags Directly from I/O checked. (see post above from Ben). This appears to be either
a. PacDisplay Issue or a Bug, Or
b. User Error (configuration/ Set-Up error).
This is a simple setup. I am using Version 8.5
[B]1. PacControl - Two Charts. [/B](Compiled charts Running in PacSim Ver. 8.5)
Chart 1 keeps track of Elapsed time and updates each second.
Chart 2 simply checks to see if I/O unit (EB1 Rack) is Online and if not sends “Enable Communication to I/O Unit” command to the controller. This chart runs at 5 second intervals.
Monitors One Input from EB-1 Rack.
Displays the Elapsed Time, Control Unit Errors, and Enabled Status of EB-1 Rack.
[B]3. EB-1 Rack (firmware Ver 9.xxx) with a 4 Point Input Card and a 4 Point Auto/ Manual/Off Output card[/B]
Couple Of issues.
[U]#1 Enabled Status of EB-1 Rack. (Incorrect on PacDisplay)[/U]
When EB1 Unit is [B]physically disconnected[/B] (Ethernet Cable Removed), from time to time, this displayed status changes from Disabled to “ENABLE” state when the rack is not even connected.
Where is it getting this change of state from? From the Enable command being sent from my Comm check chart?
[U]#2 I/O point(s) from EB1 is not correctly updated on PacDisplay screen when Comm’s go from Normal to Fail to Normal again.[/U] [I](This is true for both Inputs and Outputs)[/I]
That is unless I close the PacDisplay screen and reopen it again. Then the I/O status is correctly displayed. Screen shot below is after recovering from a Comm Failure. Same thing happens when going from Normal to Failure where point on screen shows normal until I open and close PacDisplay screen.
Any Ideas as to why this is happening?
