In addition to the base load, the following handling times apply to the various I/O channels.
All times are in msec and per channel, where not otherwise indicated.

In addition to the base load of the PC interpreters (included in base load given above), the CPU
load generated by the PC system is composed of the following parts:
• PC element execution. The PC element manual contains information on the load from each
PC element.
• Reading and writing of data to/from the data base. Each time a value is read from the data
base to a PC element, or written to the data base from a PC element, 2 microsecs are spent.
When a process output channel is written, add the time for I/O handling.

(VALUE changed)
(1) Channels with NORMAL_TREAT = 1 (event handling selected) will give rise to
increased load when the event occurs, which means VALUE changed (DI) or
LIMIT exceeded (AI), this is not included in the table. However this is taken care
of by having the stipulated reserve capacity.
