Please find a link to our conventional PLC upgrades here. Unfortunately, due to key hardware components being unavailable, we are unable to offer the S57 conversion but we are still converting many legacy systems from Rockwell and Siemens to the latest state-of-the art hardware

Siemens S5 to S7 Conversion

Rockwell PLC5 to Control Logix

You can find our legacy case study on the S57 processor here and here: S57 Upgrade presentation

A risk-free solution to Siemens S5 PLC replacement using our new S57 processor.

New for 2019 is the ability of the S57 processor to integrate with TIA Portal for the ultimate in future proofing! Only this controller allows the flexibility to upgrade complex automation plants from Step 5 to TIA Portal in controlled, planned stages. It can to be incorporated under Siemens TIA as a CPU416, emulating one of the most powerful processors in the TIA range. Full information is available here.

Sustainable and Eco-Friendly Drive Technology from Optima

The innovative sinamics G220 variable frequency drive from Siemens not only helps reduce harmonics (Gary Wilcock) but is also a more sustainable drive choice. Let us explain.

The animation below shows the draft panel layouts for 8 drives using the G120 drives along with the required input and output reactors due to the long cable lengths involved for this installation.

Shown on the right of the animation is the draft layout using the new G220 drives.

The new G220 drives, allow us to accommodate double the number of drives in one cabinet as no chokes are required.

It has helped Optima Control Solutions Ltd make this a more sustainable design.

Not only have we have reduced CO2 emissions in transit as the cabinet is lighter, we have also reduced the amount of minerals required to build by avoiding additional copper in the line chokes and steel in the chokes and cabinets.

The fusing for the other 8 drives has been moved to an adjacent cabinet where there are other drive sizes located. The control panel build is now underway.

A big thanks to Ben Poole, too for his timely demonstration of these excellent drives. Sustainability CleanTech
