PLC และ SCADA Jobs

I am looking for an experienced Allen-Bradley PLC / Rockwell Automation engineer with Studio 5000 access. We have a folding machine with an Allen-Bradley controller. The clamp sequence often fails to validate unless the operator “double pumps” the pedal. Symptoms: Clamp reaches target pressure (~140–150 bar) Position and pressure are stable PLC does not always progress to next step Requires second pedal press to complete clamp Auto mode works more reliably than manual This strongly indicates a clamp validation timer / logic condition in the PLC. Scope of Work: Connect online to the PLC (local or remote) Monitor clamp sequence live Identify which condition or timer is preventing validation Adjust logic/timing if required (with backup) Verify correct operation...

I already have a complete running PLC program developed in Siemens TIA Portal V20 for: PLC: Siemens S7-1200 (CPU 1212C) HMI: Siemens HMI (compatible with TIA Portal V20 project) The machine is already operational. I now need specific modifications and corrections in the existing logic. Scope of Work 1 Open and fully review the existing PLC and HMI project. check the list of required changes that I have mentioned inside the project files. the required logic changes properly. there are no conflicts with existing blocks, functions, or interlocks. that all modes (Auto / Manual / Safety logic) behave correctly after modification. the updated project file with clean structure and comments where required. 7. Install the program remotely on PLC and HMI Important – Read Before Qu...
