Hydrogen Filling (MEGC, cylinders & bundles) is a demand-based process. Demand is created by the requirement to fill the asset(s) (MEGC, cylinders & bundles), placing the Filling Control system at the heart of the process. That is why we have designed our Filling control system (AiFill) to integrate with the other discreet Control Systems on a Hydrogen Filling Plant, in the most economical and efficient way possible.
Design
Standard configurations for fast software deployment; Developed with future expansion in mind; Flexible to support external interfaces;
Secure
Robust user management; Security hierarchy for system integrity; RFID compatible; Defense in Depth strategy;
Operate
Simple UI for operators; Full plant oversight for management; Layer based approach for detail; Full diagnostics for swift problem solving; Simple Recipe management;
Optimise
Comprehensive logging of fill data; Historical data for plant optimisation; Full trending capability at runtime; Dashboards of metrics;
Recipe based
Easy creation/modify by Client; parameters for filling; held in SQL database
Sequences
Easy creation/modification by Client; execution order of tasks for filling; held in SQL database
Sequence Design
Utilising a user friendly flow charting approach
Parameters creation
All technical parameters are explained in each step to ensure the correct values are entered.
Parameters history
Saved during commissioning meaning the user does not need to reengineer these every time
IRIS
Strategic advantage by saving costly engineering overheads to alter fixed sequences should operations change. Engineers can optimise the fill processes using historical data from past fills
Security
To ensure only authorised users can import recipes to the live system
Providing reliable and globally supported solutions is paramount to ensuring maximum operational uptime. Based on this, our systems are configured using World Leading brands;
Hardware
PLC’s Siemens S7-1500 based; long-term support; compact IO; direct mounting filling module
PLC Software
Siemens TIA PORTAL; Compliant with IEC61131-3 for programming Languages; IGAS use a mix of Ladder, S7-Graph, SCL and CEM
Ignition SCADA
HMI PC based using Windows 10 LTSC (Long Term Support Channel); Central system – changes reflected on each device instantly; 21” touch screen; Fixed or pedestal mount; RFID login option
Database
MSSQL database; Each Step of fill is recorded for later information
