Section 2: Configuration
April 2015
Configuration
1, Sensor 2, Differential, Average, First Good and Terminal temperatures. Min/Max Tracking only
records temperature maxima and minima obtained since the last reset, and is not a logging
function.
To track maximum and minimum temperatures, Min/Max Tracking must be enabled using a
Field Communicator, AMS Device Manager, Local Operator Interface, or other communicator.
While enabled, this feature allows for a reset of information at any time, and all variables can be
reset simultaneously. Additionally, each of the individual parameter’s minimum and maximum
values may be reset individually. Once a particular field has been reset, the previous values are
overwritten.
Configure min/max tracking with a Field Communicator
From the HOME screen, enter the Fast Key sequence.
Configure min/max tracking with a AMS Device Manager
1. Right click on the device and select Configure.
2. In the left navigation window select Manual Setup.
3. On the Diagnostics tab, there is a group box labeled Sensor and Process Diagnostics;
select the button for Configure Min/Max Tracking.
4. Follow the screen prompts to Enable and configure the settings for the diagnostic.
Configure min/max with LOI
Reference the figure below to find the path to Configure Min/Max in the LOI menu.
Figure 2-22. Configuring Min/Max Tracking with LOI
* Available only if option code (S) or (D) is ordered.
2.12 Establishing multi drop communication
Multi dropping refers to the connection of several transmitters to a single communications
transmission line. Communication between the host and the transmitters takes place digitally
with the analog output of the transmitters deactivated.
