About Us


Design Technologies staff are experts at Siemens PLC installations. S5 or S7 ! If you are thinking about upgrading or converting, you should be talking to us.

Some Siemens S5 parts have already become redundant, and will no longer be available for supply, except as spare items. You should already be planning your upgrade path.

Design Technologies has many years' experience in both S5 and S7 installations, and can therefore offer you an optimum upgrade path, with minimal effect on your production.

We have developed upgrade paths for various installations, in order to minimise costs and also to reduce the impact on production.
