The parameters that are used for component communications are shown with a gray background in the
following diagram. All of these parameters are displayed if you set the Protocol Setting parameter to
cmp
. (Some of the parameters are always displayed.)
This section describes the parameters that are used to calculate the set point. The other parameters
are the same as for programless communications. Refer to
6-2 E5

C Setup
. To use component com-
munications, the input type and, if an analog input is used, the decimal point position must be set to the
same values for all of the E5
@
C Controllers. The operation will not work correctly if the position of the
decimal point is different.
