Issue When adding points in 3 rd party OPC client from Vista OPC server for the 1 st time, the response speed is very slow. For example, for about 1000 points, there will be about 20 minutes to finish the 1 st time insertion. The LTA is Xenta server. Environment Vista OPC Server Xenta Server Cause A Xenta server can only read maximum 10 to 15 values per second on the Lonworks side. And for Vista OPC server, it will poll all the points for their values from controller when these points are added in 3 rd party OPC client for the first time. So the communication load will be very high for this process, especially for huge amount of points added simultaneously, which exceeds the LonWorks communication capability of Xenta server. Resolution To solve this issue, the OPC server computer can be disconnected from the LonWorks network first. Then add these points in OPC client when the OPC server is offline. The speed will increase greatly. Then connect the OPC server to the LonWorks network, and the fresh interval of the first will also be very quick.

Issue What voltage should be seen across conductors on an Infinet bus? Environment Infinet RS-485 Cause Communication issues on RS-485 bus. Resolution  Measuring Ground Potential Signal Potential refers to the horizontal plane along which signals are sent and received with respect to ground.  RS-485 requires that all devices communicating with each other be at a reasonable ground potential. Measuring the ground potential of any Infinet controller Use a voltmeter to measure between the earth ground connection (for power) and the Infinet shield connection.   Measuring the ground difference between the Infinet controller and the ground at the InfiLink or CX/NetController (shield grounding point). Set the multi meter to measure AC voltage; measure and record the AC voltage (ACV) between + and -. A reading higher than 2-3 volts indicates a grounding problem. Set the multi meter to measure DC voltage; measure and record the DC voltage (DCV) between +and -. A reading higher than 2 to 3V on either voltage indicates a grounding problem. Calculate the combined voltage using the following formula. (1.4 X ACV) + DCV = Combined Voltage. If the combined voltage is greater than 7 a grounding problem exists
