Check length parameters and measurement

The system provides data related to two different bunch length measurements for the Operators, one for each pyrodetector. This is the PyDM screen that can be used to check the system:

The streaming of the waveforms can be turned on or off to reduce the data from the ATCA to the CPU. The Operator can choose 4 different status for the stream: Running, Maintenance, Test, and OFFLINE. The first 3 don't change the behavior of the streaming, they are used only for alerting other users. "OFFLINE" is the only status the effectively shut down the streaming.

The Sum and IMAX are calculated by the firmware. TMIT is provided by the BMP IOC and sent to the firmware as described earlier. The TMIT value is replied back by the firmware and the software publishes it as the PV we can see on the screen. IMAX can show "nan" in case an error flag is sent by the firmware. In the example above, the pyrodetector is disconnected and, so, Sum is calculated on noise, resulting in a negative number. IMAX was also negative and the firmware alerted us about this, what we can see as a "nan" inside a pink box.
