FUNCTIONS AND BASIC OPERATIONS
6.1
Overview
DevCom2000 allows the user to monitor and configure a single device at a time in the field. Each device is
associated with the DD when the device information is present. A DD may contain any of the following
parameters/elements:
Variable
A variable is defined as the data contained in the device (e.g. Device Firmware Version). There are two types of
variables:
Editable Variable – It allows the operator to modify the value and download it to the device.
Non-Editable Variable – It is a read-only data from the device.
Edit Display
This option is used to view a group of parameters. You can also modify a single parameter from this group, based
on which other parameters of the device get altered.
For example, if the Engineering Unit of the device is modified, the corresponding Low Limits and High Limits
change as per the Engineering Unit set.
Method / Standard Operating Procedure (SOP)
This option helps to perform various tests on the device for instance, Self Test and Loop Test. A Method or SOP is
a series of steps that are executed in a sequence results in the completion of some device related tasks. When a
method gets invoked, it gives various warning messages and options to the user, by which the user can thoroughly
test the device. If a test is aborted by operator command at any stage of the sequence, the method invokes
additional steps to bring the device back to its original state before the test.
