The transaction group items were set to OPC Read Data Mode to ensure that the data was consistent, and time-synchronized.This consisted of multiple event queues on the PLC, and a trigger tag for the PLC to set off transaction groups within Ignition.Handshake-based event-logging framework between Ignition and more than 40 Rockwell PLCs.To achieve robust traceability as samples moved throughout the lab, DMC created the following architecture within Ignition: Supporting rapid development and shifting requirements. Ignition facilitated multiple tiers of users and associated permissions.Ĥ. Providing intuitive operator interfaces and dashboards to control, monitor, and support performance of the lab. The lab equipment is not able to communicate directly with PLCs, so Ignition relays commands from PLCs to the lab equipment and statuses from the lab equipment to the PLCs.ģ. Acting as an information broker between PLCs and lab equipment. This ensures all steps of the process can be traced without any potential for lost data.Ģ.
Ignition processes them and sends them all to a database. Events occur multiple times per second throughout the lab across many PLCs. Providing event logs and sample traceability. The most important challenges Ignition solved were:ġ. Ignition is the only SCADA platform that could have allowed DMC to hit a moving target at this scale and pace. With more than 40 separate PLCs all triggering actions that impacted the samples, Ignition was critical to unifying the process data and allowing Ginkgo to extract meaningful testing results.Īll of this occurred while the biological process, physical lab layout, and system requirements were changing daily. Sample traceability is of utmost importance.
#INDUCTIVE AUTOMATION IGNITION BIND TO ALL INTERDFACES SERIES#
The lab is highly automated once a rack of samples is placed on the line by an operator, it makes its way through a series of work cells with no human intervention. Ginkgo designed and built a new sample-processing lab very quickly. Ginkgo Bioworks expanded its automation capabilities in response to the COVID-19 pandemic and the need for increased nationwide diagnostic testing capacity.
