Issue Unable to communicate as lights are solid red on the front panel. Environment All versions of I/Net Software. Cause The lights indicate that there is no communication to the device which can be caused by the failure of the power supply. This has been a known issue as those devices are not manufactured anymore and needs to be replaced. Resolution Replace the Legacy NPR 2000 with the Xenta 527-NPR.

Issue Xenta Server Error: Ethernet autonegotiation error (Error#: 59) Environment Xenta Server System Error log Xenta 527 Cause The Ethernet negotiation error comes from bad connection with the Ethernet switch. The negotiation is the low level negotiation between the PHY (physical layer) interface on the Xenta and the PHY on the switch. It negotiates speed (10/100 Mbps ) and duplex. This error can indicate a bad cable or other problems with the switch. Resolution Replace any patch cables Replace connectors on any suspected bad cables Use a different port on the ethernet switch. *Note that the Xenta Server Ethernet port is only capable of 10 Mbps. Speed negotiation is unnecessary if the port on the switch can be manually configured.

Issue Port 23 is opened through Telnet and can provide a security access breach into a system. Product Line TAC INET Environment All versions of I/Net Software on All Supported Operating Systems. Cause When the Delta Debug tables are set to 1 or 2, it opens up port 23 for use but also Telnet can be used as well. Resolution The following steps need to be followed to resolve this issue: Go to Run and type regedit Open up HKEY_LOCAL_MACHINE Expand the Software tab and expand CSI-Control Systems International On x64 Based Systems the above folder is located under the HKEY_LOCAL_MACHINE\Software\WOW6432Node Open up the Configurations tab and click on the Active Configuration that is currently running in I/Net On the right side window, scroll down to Debug Tables, right-click and modify the setting Change the value to a 0, close out of it, close I/Net and I/o server and restart it again. P.S. This should close that port but be aware that Telnet would not be able to function when this is done.

Issue Cannot restore SAV file to Controller be it a 7798, 7793, 7716, 7756, 7718, etc. and possibly cannot save controller in Netcon Environment I/NET site with controllers Cause Need to restore database to controller but cannot save in Network Configuration Resolution Problem is the database does not have what Network Configuration sees, then you have the + symbol in Cnf on the far right. If you save, then exit Netcon, then go back into Netcon and it still shows a + symbol in Cnf, then the save is not being saved to the database. Remove SQL database and create fresh clean database. Then save the controller in Netcon then you can restore the SAV file to the controller. 

Issue Can I use a uninterruptible power supply for controllers? UPS Environment site requiring constant power supply or unstable power from grid and need to take into account power supplies Cause Can I use the CX99-PSU-BATT for an ACX5720 controller? If not, then what can I use if the customer wants a UPS for each controller. Should I use a big UPS for the system and supply the controllers from it?   Resolution The CX99-PSU-BATT is 70VA 120/240VAC and really designed for the CX9900 PSU. It is suggested to get one of our APC UPS and run the proper voltage transformer to the ACX5720. The ACX 57xx series is rated with a 24VAC 90VA or 12-28VDC 50W on the power supply which I recommend due to devices which connect to this controller and require power. i.e. door readers UPS or uninterruptible power supplies are available from APC by Schneider Electric.  Background The power drawn by computing equipment is expressed in Watts or Volt-Amps (VA). The power in Watts is the real power drawn by the equipment. Volt-Amps is called the "apparent power" and is the product of the voltage applied to the equipment times the current drawn by the equipment. Both Watt and VA ratings have a use and purpose. The Watt rating determines the actual power purchased from the utility company and the heat loading generated by the equipment. The VA rating is used for sizing wiring and circuit breakers. The VA and Watt ratings for some types of electrical loads, like incandescent light bulbs, are identical. However, for computer equipment the Watt and VA ratings can differ significantly, with the VA rating always being equal to or larger than the Watt rating. The ratio of the Watt to VA rating is called the "Power Factor" and is expressed either as a number (i.e. 0.7) or a percentage (i.e. 70%). The power rating of the UPS UPS have both Watt ratings and VA ratings. Neither the Watt nor the VA rating of a UPS may be exceeded. In most cases, UPS manufacturers only publish the VA rating of the UPS. However, it is a standard in the industry that the Watt rating is approximately 60% of the VA rating, this being the typical power factor of common loads. Therefore, it is safe to assume that the Watt rating of the UPS is 60% of the published VA rating. How to avoid sizing errors Using APC sizing guidelines or and APC Configuration can help avoid these problems, as the load power values are verified. Equipment nameplate ratings are often in VA, which makes it difficult to know the Watt ratings. If using equipment nameplate ratings for sizing, a user might configure a system which appears to be correctly sized based on VA ratings but actually exceeds the UPS Watt rating. By sizing the VA rating of a load to be no greater than 60% of the VA rating of the UPS, it is impossible to exceed the Watt rating of the UPS. Therefore, unless you have high certainty of the Watt ratings of the loads, the safest approach is to keep the sum of the load nameplate ratings below 60% of the UPS VA rating. Note that this conservative sizing approach will typically give rise to an oversized UPS and a larger run time than expected. If optimization of the system and an accurate run time are required, use APC sizing and Worldwide Web configuration tools.  

Issue Cards added to a system are not working and this messages shows up in AMT. Environment All versions of I/Net. Cause There could be a change in the configuration that does not match up with the link causing the message to be generated once the information was sent down to the DPU. Resolution To resolve this issue, follow these steps: 1. Verify that the configuration used is correct as far as a direct connect or TCP/IP. 2. Make necessary changes if not to match configuration. 3. Connect to the system, select Access Doors and verify that it does not have "Link Lost" displayed. 4. Control a door and verify that the correct message is displayed in the Messages Window.

Resolution This issue has been rectified in 2.41A and above. I/NET Software are available for licensed Partners to download on The Exchange Download Center.

Issue User must not have access to change group access nor individual access. Environment All versions of I/Net software and OS. Cause If there are multiple Tenants in a building using the same software but the only changes that a user can make are those that they have access too and the others should be left alone. Resolution In order to resolve this, the following steps need to be followed: 1. Go to Edit/Host Computer/Passwords, select the user who the limitations would be set on. 2. Select Modify and on the bottom row there is a Tenant Button, it opens a Host Passwords - Tenants Editor. 3. Select a Tenant and verify that they have either Full or Limited Access. 4. If it is going to be limited, highlight and click on the Limited box, this brings up the Host Passwords - Groups Editor. 5. Select the box for Read Only access for which ever groups that access will be limited for and click on the OK buttons to close out. 6. Logoff then logon again as that user and verify that the limitations set about has been incorporated.

Issue Some managed switches have settings that have to be configured to match the communications type and speed of the connected devices. Environment Xenta 511, 527, 527-NPR, 555, 701, 711, 721, 731, 911, 913 Cause Some managed switches have to be configured to match the communications type and speed of the connected devices. Resolution Most switches automatically detect the speed and configuration of the connected devices. However, for those site where these configurations must be manually configured, the specs below should be noted. All Xenta Servers use a standard 10 Base T network port. These ports operate at 10 Mbits/sec. and are half duplex.

Issue Repeater for large distances between card reader and controller Environment Site with iBMS using Access Control Cause Site has large distances between card reader and access controller Example: maximum permissible cable length for a HID reader to the ACX controller - the length depends on the gauge of cable used: Wiring Distance Card Reader to ACX: 200 ft. (60.96 m) max using 22 AWG 500 ft. (152.4 m) max. using 18 AWG Resolution The communication between access controllers and card readers is using RS-422. Access controllers supply power as well as data to the card readers. To increase beyond the recommended guidelines a repeater can be used which extends the data length. A separate power supply would have to be installed to power the card reader.  Solutions for RS-422 data repeaters are: Westermo Cypress Computer Schneider Electric PSS in no way is endorsing nor including support of Cypress Computer & Westermo products in the following example: An example of a site using Continuum: the project used the Cypress SPX-1300 and was able to run the cables up to 3000 meters as long as the reader was powered from within the lift car, he utilised the Continuum elevator add on module with the Net11 and AC-1 Module per car.

Issue Command Error in AMT MCU lost in AMT Environment I/Net AMT Cause If the I/Site loses contact with its SCU and there are a Global / Indirect point associated with this unit a Command error will appear in AMT. Resolution There can be various reasons for a SCU to go offline, it can be either power loss or grounding problem. Check the unit and the cables, it can also be that the unit is broken and needs to be changed. Check TCON312 and TCON313 for installation help.

Issue A change is made to a public signal in TAC Vista Workstation, which was created in a Xenta Server XBuilder project, changed back to the initial value after performing a download to this Xenta Server. Environment Xenta Servers (Xenta 511, Xenta 515, Xenta 555, Xenta 527, Xenta 701, Xenta 711, Xenta 721, Xenta 731, Xenta 913) XBuilder Tested with Windows Server 2003, Window XP SP3 Cause If a path name is changed of a signal, for example, change the "the site name" folder name to another name, Vista consider this change as a major change, and Workstation will not be able to find the new path of the signal. Therefore, the signal will return to the initial value which is initialized in the Menta object. Resolution Suggestion is making all the infrastructure change at the beginning if you can. If there is a need to change the path, make sure all the initial values are reflect to the current values in Workstation. Then, make the download to the Xenta Server.

Issue Some users are unable to see I/NET values on a graphics page displayed in a 527 Environment Xenta 527 TGML Cause User permissions on the 527 must allow the user to access the I/NET links that are being displayed Resolution Log out of the 527 Log in as the root user In the Configuration folder, select User administration Modify the user that was having issues.

Issue Modbus TCP/IP Server is not an option when programming a Modbus Gateway in an Xenta Server. Environment Xenta 913 Xenta 7xx XBuilder Cause There are only 3 Modbus Interface configurations for Modbus in an Xenta Server. Modbus RTU Client ("Master"), Modbus serial line master on a network Server ("Slave"), Modbus serial line slave on a network Modbus TCP Client ("Master"), Modbus TCP client to a server or router on a network Modbus TCP Server is not possible. Resolution Modbus TCP/IP can only be configured to be a Client (Master) in an Xenta Server. A solution if TCP Server is absolutely necessary would be to use an IP to 485 converter, such as an EGX100, and use the RTU interface.
