C-T Digital Temperature Controllers Programmable Type Communications Manual (H186)
This section describes the settings necessary to start component communications and the set point
calculations that are used to perform target point calculations at the slaves.
To perform component communications, change the parameter settings in the communications setting
level to the values that are given below.
*
Parameter details are the same as for programless communications. Refer to
.
Note: To use component communications, 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-T/E5
@
C Controllers. The operation will not work correctly
if the position of the decimal point is different.
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.)
*
These parameters are displayed regardless of the setting of the Protocol Setting parameter.
Note: The Communications Data Length, Communications Stop Bits, and Communications Parity parameters in
the communications setting level are not displayed.
