Should the conditions be such that a particular table (1, 2 or 3) has been selected as described
in Section 3.5.2, then the output from the selected table, at any given time, will be passed
directly to the Logic Output.
Therefore, up to three different responses to the same input, or three different responses to
different inputs, can become the input to another function block, such as PWM Output. To do
this, the “
Control Source
” for the reactive block would be selected to be the
‘Programmable
Logic Function Block.’
In order to enable any one of Programmable Logic blocks, the “
Programmable Logic Block
Enabled
” setpoint must be set to
‘True’
. They are all disabled by default.
Logic is evaluated in the order shown in the figure below. Only if a lower number table has not
been selected will the conditions for the next table be looked at.
The default table is always
selected as soon as it is evaluated. It is therefore required that the default table always
be the highest number in any configuration.
