PLC Programming a First Scan Bit In Studio 5000 Version 32 | Batching PLC Day 27
Using a First scan bit in Studio 5000 in a ladder logic set of PLC code.
First scan bits are a very effective way to control system start-ups from power losses among other issues. They can be used for simple tasks like resetting common faults, turning off systems, setting systems to a default state, & much more.
As we are building out this batching station project for YouTube, we wanted to cover as much PLC programming as we can for this example.
If you haven't seen the videos leading up to this then feel free to subscribe to this playlist & watch all that we are teaching here.
Teaching:
✔️ PLC programming using Studio 5000
✔️ HMI programming using FactoryTalk View Studio SE
✔️ System communication using RSLinx classic
