The
Source is a display only field that allows the user to view the current input source for the monitor point. In
order to change the input source and access other settings for the monitor point, press the
“Setup” button. This
will provide access to the
“Monitor Point Settings” screen.
The
Tagname field is used to enter a specific name for the monitor point, up to 11 characters in length. This
name will be used throughout the MCT runtime application and can be used to provide a more detailed
description as to the value the input indicates in the application. Default tagnames are Monitor1, Monitor2, etc.
NOTE: It is not necessary to wire or use all inputs of the monitor input modules (or second input of control
loops) if they are not required for the application. Unused inputs will be ignored by the MCT. The
MCT will only utilize the inputs individually configured as monitor points.
4.3.1 Monitor Point Settings
The Monitor Point Settings screen provides a drop-down menu selection that allow the user to set the Input
Source for the input (monitor card 1 or card 2) and which input to use from the selected card. In addition,
certain CM software versions such as the
“FD30”, also allow the second input of the loop controls to be
configured as monitor points. These versions will allow the selection of
“Loop Input 2” from the input source
drop-down menu.
Once the input source selection is made, the
Input Number selection will provide the corresponding input
selections for the source selected. These will be inputs 1-6 for RTD cards, inputs 1-8 for analog and
thermocouple cards or the individual loop names for all loops configured in the system. If the selected monitor
card is not used, or loop input 2 is selected but is not available on the current CM version, the selection will be
cleared and the user will be alerted to make another selection.
NOTE: It is possible to assign the same monitor card input or loop to more than one monitor point.
The
Eng Units field is used to enter the engineering units for the input up to four characters maximum. This
value is shown on the loop and overview screens in the MCT runtime application. When the monitor input
module is an RTD or Thermocouple type, the MCT will change the units between
“C” and “F” based on the units
selection on the Offline\Setup\Units screen. If the monitor input module is an analog input type, the engineering
units entered here will remain as entered regardless of the temperature units selection.
The
Decimal Pos field is used to select the decimal point resolution for the monitor point. All readings in the
MCT will be displayed using the selected resolution. Temperature input types have a maximum resolution of 1
decimal point. The analog input types can be displayed with a resolution of up to 3 decimal points.
