Our customer asked us to replace their old Red Lion HMI with a ProFace screen on their setting machine.
The existing screen was confusing to use as there was a lot of unnecessary information on key screens. We redesigned each screen so that the operators are only presented with information relevant to the task they want to undertake.
We chose the ProFace PFX SP5700TPD for this project. Its 15” widescreen format meant that we could fit some nice graphics on this.
As well as upgrading the HMI we also changed the PLC code so that the machine was no longer sequence-based. The new code allows the machine to be moved to any position in manual mode and can continue its process when switched back to automatic mode.
