Modifying the Configuration Files Manually

The steps to configure the EtherNet/IP Machine Adapter are:
1. Open the file com.ge.ac.machineadapter.ethernetip-0.xml for editing.
2. Edit the data contained within the dataNodeConfigs element:
Note:
Note:
EtherNet/IP Machine Adapter
• Each channel element corresponds to one EtherNet/IP Field Device.
The name attribute must contain a unique name given to this Field Device node.
—
The protocol attribute must specify the protocol ("CIP" or "PCCC") used by the Field
—
Device.
The Rockwell Automation CompactLogix uses the CIP protocol. The Rockwell Automation MicroLogix uses the PCCC
protocol.
The IPAddress attribute must be set to the IP address for the Field Device.
—
The Port attribute must be set to the port number for the Field Device (usually 44818).
—
• Each tags element contains all of the tag elements for one Field Device.
• Each tag element corresponds to one variable on the Field Device.
The tagName attribute must be set to the name of a variable on the Field Device.
—
For CIP protocol, the tagName is the symbolic variable name. For PCCC protocol, the tagName needs to be
formatted as follows:
[FileType][FileNumber]:[ElementNumber].[SubElementNumber]
or
[FileType][FileNumber]:[[ElementNumber]]
The TsTagName attribute is an optional parameter and can be set to the tag name that is
—
desired to be associated with the variable for sending data to Predix Time Series Database.
It must have a unique name relative to other tags in the same Predix Time Series Database.
If not specified, the above configured tagName will instead be used.
• Inside the dataSubscriptionConfigs element, each dataSubscriptionConfig element
corresponds to a desired subscription, which includes one or more tags configured to be
read at a given update interval.
The name attribute must be set to a text name that uniquely identifies this subscription.
—
This name is later used in the Hoover Spillway configuration file to configure the
subscription as data released to a given Data River.
The updateInterval attribute must be set to the desired time interval between consecutive
—
attempts to read the tags configured for this subscription. Specific format to be followed
is <NUints> where N is the interval numeric and Units can be ms (Milliseconds), s
(Seconds), m (Minutes), or h (Hours)
The startPointUnit attribute is the unit of measure applied to the startPointOffset
—
attribute. Possible values include "SECONDS" "MINUTES" and "HOURS". If this attribute is
not present, the default unit of measure is SECONDS.
The startPointOffset attribute is the amount of time to wait after the OSI PI Machine
—
Adapter starts to begin reading configured tag data. The unit of measure defaults to
