PLC & SCADA Jobs

I need a complete PLC application—logic and HMI—that will fully automate both the Ultrafiltration (UF) and Reverse Osmosis (RO) sections of a water-treatment skid. The control scope covers every critical field device on the plant: pumps driven through VFDs, globe and on/off valves, flow meters, level transmitters (LT), level switches (LS), pressure transmitters/switches (PT/PS), and the pH / conductivity probes that protect membrane integrity. The sequence must manage start-up, normal production, back-flush and CIP where relevant, while enforcing interlocks on pressure, level and quality limits. Alarms, trends and manual-override features should be available from an intuitive touch-screen HMI so operators can see live values and step through maintenance modes without needing a...

I need a complete, reliable fingerprint-based door control for several designated rooms in our facility. Because we want true physical security, cards or PINs are off the table; fingerprint recognition is the single authentication method we will use. Scope • Advise on hardware (reader, controller, electric strike) that ships easily to Indonesia and is proven in small-to-medium deployments. • Install and configure the units on two interior wooden doors. • Set up simple management software so I can enrol users, assign them to specific rooms, and download entry logs in CSV or Excel. • Provide a short hand-over session and written guide in Bahasa Indonesia. Acceptance • Only authorised fingerprints open the doors; failed attempts stay locked. • Syste...
