Telematics

Telematics signal ID 19 data type real is showing up in our modem data stream as 0 when program is on a functioning machine. If the program is on our test bench that does not have any I/O, the value is exactly the value we would expect it to be. We have done lots of testing to narrow down the root cause. Our best understanding right now is that when the program is running on a real machine, the I/O is changing values. That seems to be the difference between the test bench and a real machine. Some of those I/O values are sent to display page items over the DIAG CAN from an MC43FS address tag of 0 to a display address tag 1. If we set up the display to never show a page on a real machine, signal ID 19 is the exact value we would expect it to be. Is this a known issue or has anyone else experienced something like this? We are using IQAN design 7.04.8.10088. We have also used IQAN design 7.05. The issue still exists.
