(1)
Use the larger number for addresses beyond 2048 words in the controller’s data table.
(2)
Timing for immediate I/O instructions is the time for the instruction to queue-up for processing.
(3)
Calculate execution times as follows: (time) + (quantity of additional parameters)(time/parameter). For example: if you are passing 3 integer parameters in a JSR
within a PLC-5/11 controller, the execution time = 16.1 + (2)(3.8) = 23.7 ms
