I have a telemetry system that currently has 37 RTU's and uses Lookout 6.0.2. We are adding an additional site ( pump station with controls) and I am experiencing a probleml when making the "connection" between a control object (00001) and a switch. With the RTU up and running without the switch connection, modbus statistics show valid response frames at 100% with no errors. Input states can be changed and the software works properly and dispays the correct state. AS SOON as I make the connection between the control object and the switch, modbus statistics show "no response" errors immediately and the software X's out all of the dispayed objects for that RTU. If I change the switch position, the RTU responds and turns on or off the corresponding output even though the software says the RTU in not responding. I have tried creating a new modbus driver and making a simple connection between a control object and a switch with the same result. If I re-address my RTU to a lower number that is not in use, such as 13, everything works normally. I do not have the luxury of just going to a lower number as the system is currently undergoing expansion and will continue to grow beyond the mark of 40 units in the field. Anybody seen this before?
Thanks
