This object contains attributes common to many Metasys system objects. These common attributes are described in the Common Object Attributes section. This section includes attributes of the Focus/Configuration tab and the Diagnostics tab. See the Object and Feature Tabs section for information on the attributes that appear on the other tabs of this object (for example, the Hardware and Options tab appear on point objects).

Note: In the Notes column, attributes marked with the letter C are configurable, and attributes marked with the letter W are writable.
Table 1. IP Field Controller Object Attributes - Focus/Configuration Tab

Attribute Name


Initial Value


JCI System Status


Reflects the current status of the system.

Alarm State


Indicates that the object transitioned into alarm or unreliable conditions.




If True, allows integration between the Metasys system and the IP field controller.

In Test



Displays True when a Control Sequence in the device is currently in a test mode. When True, the device is marked offline, although communication with the device is acceptable.




Indicates whether the IP field controller is offline.

Vendor Name



Identifies the manufacturer of the device.

Model Name



Indicates the product code for the device.

Startup Code Version


Specifies the version of the Startup code running in the controller. The Startup code is responsible for initial power up operations.

Fixed Boot Version


Indicates the version of the Boot code in the field device. The Boot code is responsible for loading the Main code.



Displays the device orderable product code.




Indicates the physical location of the device.

COV Min Send Time


15 seconds

Configures the object to send COV messages on a periodic basis instead of on every change of value that exceeds the COV Increment.

Local Time


*.*.*.0 (HH:MM:SS AM/PM)

Indicates the time of day. If the device has no knowledge of time or date, Local Time is omitted.

Local Date



Indicates the date. If the device has no knowledge of time or date, Local Date is omitted.

UTC Offset


0 minutes

Indicates the number of minutes offset between local standard time and UTC. The time zones to the west of the zero degree meridian are positive and those to the east are negative. Subtract the value of the UTC Offset from the UTC received in the UTC Time Synchronization service requests to calculate the correct local standard time.

DST Status



Indicates whether daylight saving time (DST) time is in effect (True) or not (False).



Object Name:


Indicates the graphic associated with the object.

Graphic Alias



Indicates a portion of the graphic’s item reference, up to and including the name of the folder containing this object or the controller containing this point.

Item Reference


Contains a unique reference name for the object that is the full path name of the object through the All Items navigation tree using the unique identifier you specified when you manually created the object.




Displays the version number of the object software code.

Table 2. IP Field Controller Object Attributes - Diagnostic Tab

Attribute Name

Initial Value


CPU Usage


Specifies a running average of CPU usage over the last 50 minutes. The value is updated every 30 seconds. The running average is calculated by adding or subtracting 1% of the difference between the current and average CPU usage. The value may not be meaningful until 50 minutes after a system restart. A value of 0% means the CPU is 100% idle. A value of 100% means the CPU is 0% idle. A value of 50% or less is considered OK, although other performance indicators should also be assessed. Under device simulation, the value is 0.

Flash Usage


Specifies the estimated percent of flash memory currently in use. The percentage is based on the portion of flash that is designated for use by the user’s database. The value is updated on device startup, after a database archive, sync or download from the SCT (offline mode), and by manual command (Update Flash Usage). A value greater than 100% can affect system reliability now or in future software releases. No restrictions are in place to prohibit use of flash over 100%.

Memory Usage


Specifies the percent of system RAM that is currently in use. It is calculated as follows:

Total commit charge x 100

Display Precision = 0.01

COV Increment = 0.1

Object Memory Usage


Specifies the percent of the object database that is currently in use. Each object created consumes memory within the object database. This attribute can be used to help determine the device’s capacity for additional objects; however, other performance indicators should also be assessed. Generally, the number of objects you define determines the object memory usage. This attribute is valid on the Engine hardware and under device simulation.

Note: If you have a large number of objects, the object memory usage increases and the archive.moi file size increases also. The archive.moi file is stored in flash memory.

Also, an attempt to create an object known to require X bytes of object database may fail even if more than X bytes are available in the object database. This is because the object database is composed of multiple blocks. If the free space of each block is fewer than X bytes, the request for X bytes fails even though the sum total of free space from all blocks is greater than X bytes.

Object Count


Indicates the number (count) of all of the object instances within the device. Objects of all classes are included.

Has Unbound References


Lists references that are not bound in the system. This attribute indicates that a process cannot find an object either because the device on which the object is located is offline, the object has been deleted, or the object reference is incorrect.
