Improvements and fixes

Linyang battery alarms name their condition, Phoenix Contact WebVisit park controllers report their limits and setpoints, and blue'Log loggers stay connected at plants with many strings and sensors.

• Alarms from Linyang containers now name the condition, such as a charge over-temperature, instead of only an alarm level.
• A Phoenix Contact park controller with a WebVisit interface now reports grid and marketer limits, and the setpoints applied.
• blue'Log loggers no longer drop in and out at plants with many strings and sensors.
