You can read it and maybe write yours too.

๐ We talk a lot about #1oo2 and #2oo3, but most trips in plants still run on simple 1oo1 logic.
๐ Plain language:
1oo1 = โone out of oneโ must act to #trip.
You have a single sensor/input. If it goes into trip condition, the logic trips. No second opinion.
๐ Where you see 1oo1:
๐น Basic permissives and #interlocks
โ Simple trips on PLC/DCS
๐ก Low-risk shutdowns
๐ก Sometimes in SIS/ESD for non-critical or low SIL demands
โก Behavior with a single #sensor:
โ Sensor healthy + process safe โ
Attached: 1 image board_directors: Norwegian Boards of Directors (2002-2011) 224 networks of the affiliations among board directors due to sitting on common boards of Norwegian public limited companies (as of 5 August 2009), from May 2002 onward, in monthly snapshots through August 2011. Some metadata is included, such as director and company names, city and postal code for companies, and gender for directors. The 'net2m' data are bipartite company-director networks, while the 'net1m' are one-mode projections containing co-memberships among directors. This network has 1820 nodes and 1787 edges.
