Issue OPRIF 11.6 runs in a Command Prompt window and does not maximize to a full-screen.  This is observed on a Windows 7 computer. Environment OPRIF 11.6 Windows 7 (any version) Cause By design Resolution The Command Prompt window does not work in full-screen mode in Windows 7 as designed by Microsoft. OPRIF 11.6 was designed to work within a command prompt window.  As a result, it cannot operate in full-screen mode. By accessing the Properties of the command prompt window, it can be enlarged slightly: The Magnifier program which comes with Windows 7 can also be used to enlarge the command prompt window running OPRIF 11.6.  Screen resolution will be somewhat compromised.

Issue Second door reader (09 Door) does not work on 7920 controller Environment 7920 DPU Cause If you have defined one door in a DPU-7920, and the door's exit reader parameter is set to anything besides NO, then the second reader port automatically becomes the exit reader. Resolution If you have defined two doors in a DPU 7920, neither door can have an exit reader defined. Set the door's exit reader parameter to NO.

Issue If I have a point that is flagged for Export what is the easiest way to determine what is causing it to be exported? Environment Cyberstation Cause Determine the cause of a point to be export.  Resolution The easiest method to determine what is causing a point to be exported is to send the site to an ASCII file from Continuum explorer. Then open the dump file and search the file for all occurrences of that point name. Review each occurrence to see if there is an alarm attached or a program in a different controller that references this point. NOTE This same method is the quickest method of finding various objects that may be reference by other objects as these are often not available in listview eg. Objects referencing Alarm Enrollments, Event Notifications, Trigger points, Alarm Points, etc.

Issue When adding a physical layer Xenta repeater, or Loytec smart-switch, to split a single channel into multiple segments, there is no need to represent that repeater/smart-switch in the LON network.  It will be invisible to the LNS database, and will function only on the physical layer. Environment LON Network with more than 64 devices on a single segment Xenta Repeater, Loytec Smart-Switch Cause A single LON segment can have up to 64 devices (though a conservative recommendation is typically closer to 50).  A segment is a single LON wire that is separated from another segment either by a physical layer repeater, smart-switch, or router.  A channel can have up to 3 segments separated by a repeater with a limitation of 128 devices (or nodes) total on the channel. Resolution There is no need to represent a physical layer repeater/smart-switch on the LON drawing or in the LNS network.  It will be operating on the physical layer either amplifying signals or filtering noise and bad data, and repeating messages on the wire.  The LON network will only see a single channel without any indication that there are 2 segments, other than the fact that there may be more than 64 devices on that channel.

Issue PE program in i28xx controller controls the VAV with TriState Triac output, and the Triac output gets damaged randomly. Environment i2 controller ( i28xx , i28xx-V ) with Triac output. Cause The output channel can get damaged / burned when Triac output value is changed to +ON from -ON ( or to -ON from +ON ) without setting the output value to OFF before the change. Resolution Check the VAV control PE program and make sure the program sets the Tri-state Triac output value to OFF before changing it to the opposite value.

Issue When tunnel through a UNC using an HTTP port other than 80 the Ax Serial Tunnel will not connect and locks up. Environment R2, G3 I/A Series tunneling Cause Including the port number after the IP address when entering the Host address in the Ax serial tunnel window will cause it to lock up trying to connect with the port entered. Resolution Do not include the port number after the IP address when entering the Host address in the Ax serial tunnel window.

Issue Controlling a Forta actuator from PLC system using 0-10V output. Environment TAC Forta actuator  PLC controller Cause The PLC system is using a 0-10V control output to control the TAC Forta (MX and X1 input), powering the TAC Forta (G and G0 input)using a separate transformer. Resolution As long as the PLC system and TAC forta units are fed from separate transformers, this should cause no problem, and galvanic isolators on the control signal should not be required. Make sure to not mix up G and G0 in case several TAC Forta actuators are fed through the same transformer.
