Intro:
- Cross-platform (OS) server software platform for HMI/SCADA/MES applications that is web-based, web-managed and web-launched.
- Effective communications hub with PLC/DB/Historians.
- Other functionalities: reporting, PDF viewers, alarming (voice, SMS, email).
- Server License model with unlimited web-clients, tags, concurrent designers. Limits are generally hardware related.
- Four main parts: Gateway, Designer, Clients (Vision), Sessions (Perspective).
- Modules (plus third party modules, e.g., MQTT, MES, Edge, etc). The modules are installed/upgraded/managed from the GW.
Variations: redundancy, on-premise vs. cloud (GW/DB), GW split into back-end GW (Tags/IO) and front-end GW, multi back-end/front-end GWs with load balancer between front-end and runtime Clients, geographical spread architecture with central GW.
Linux Install:
- Download the Ignition - Linux Installer 64-bit (~2GB) from the website. Change the properties for the run file to be executable as a program (chmod +x ignition-linux-64-installer.run).
- Execute the run file (./ignition-linux-64-installer.run).
Gateway Performance:
- Allocate more memory to the gateway if needed (e.g., from 2GB to 4GB).
/usr/local/bin/ignition/data/ignition.conf
wrapper.java.maxmemory=4096
./gwcmd.sh -r- Deployment Modes: From the GW >System > Modes create at least two modes (i.e., Production, Development).
Allocate resources definitions (e.g., Network>GW Network>Settings, Connections>DB>Connections) to these modes by creating overrides and editing the settings for each mode as desired.
Activate the desired deployment mode by adding a new parameter to the wrapper in the ignition.conf file associated with the mode's name:
wrapper.java.additional.7(or the next available index)=-Dignition.config.mode=MODE_HERE(e.g., Production)
./gwcmd.sh -r
Backup/Restore:
- Project and GW Backup/Restore can be done from the GW and also a partial backup depending on selected items can be done from Designer.
