What are the data storing & viewing capacity for Alarms, Event Log and trend viewer? How many alarm, event lines I can store in PcVue? What is the maximum limit of Historic trend viewer in terms of hours and days?

Alarm Viewer
Real-time buffer - The maximum number of lines that can be displayed. Range 1 to 32000.
In On-line mode, it is the maximum number of alarm transitions that can be temporarily stored.
In List mode, it is the maximum number of alarms.
Log Viewer
The maximum number of lines that can be recorded in the display buffer. The display buffer has a maximum size of 64 Kbytes which should be taken into account when configuring this property. One character is one byte.
Trend Viewer
The maximum number of values that may be recorded in the display buffer. Normally this will be left at the default value of 10,000. However, if the application has any special requirements (for example, reducing the amount of memory required) this property may be changed. The maximum value is 36,000. Values are discarded when either the time capacity is reached or the display buffer is full.
You can check the clear explanation in the help.
Regarding the data storing, it depends your archives capacity

Thank You for your reply. In continuation with that, I would like to know that if my archive capacity is more and I have stored more number of alarms, events, trend than that of viewing capacity of the respective viewer. Then how I can read that data?
