MES 3.0
An MES enterprise network of Ignition gateways has one MES enterprise gateway designated as the root parent with root MES enterprise server-administration access.
MES enterprise server-administration includes managing the equipment on each server, server-hierarchy, and data syncing.
Setting Root or Parent Gateway sets the syncing hierarchy in the MES Enterprise Network within an Ignition Gateway Area Network (GAN).
In This Section
| Terminology | Definition |
|---|---|
| Root | The top level gateway commonly referred to as “the Enterprise”. It has no parent, ancestor or sibling. |
| Leaf | Any gateway that has no children. In the above screenshot, gateway server Site 2 is a Leaf. |
| Subtree | A part of the enterprise gateway network that has child and parent gateways, but does not include the Root gateway. In the above screenshot, Site Server 1 and Line Server is a Subtree. |
| Child | Any gateway that has a parent gateway. It may also have child gateways of its own. |
| Parent | The gateway directly connected to a gateway below it in the hierarchy. For example, the Root gateway is the parent to any site gateway directly connected to it. |
| Sibling | A gateway at the same level in the hierarchy as another gateway are siblings. In the above screenshot, gateway servers Site 1 and Site 2 are Siblings. |
| Ancestor | A gateway that is closer to the Root than the current gateway is, and is in the same path from the gateway to the Root. In the above screenshot, gateway server Site 1 is an Ancestor to Line Server. |
| Descendant | A gateway that is lower in the hierarchy than the current gateway and is in the same path. In the above screenshot, gateway server Line Server is a Descendant of Server 1. |
For discussion about architecture, see Understanding MES Architectures.
Defining Network Hierarchy:
Enterprise Root:
The top-root server handles the syncing of elements and data. The MES Monitor component provides sync-data information.
Enterprise Administration:
Bottom Up Distribution of Data
Top Down Distribution and Synchronization
Equipment and production requirements can be centrally configured
