The evolutionary steps that have been taken in automation technology in recent years and the demands placed on today's automation systems are considerable, necessitating, on a case-by-case basis, the migration of existing plant automation. The potential migration paths provide space for potential savings and offer considerable potential for optimization. In the recent past, the specialists of the BST team have put these requirements into practice so often that this has become a specialty of the engineers from Dithmarschen and Bremen. Whether from S5 to S7 or Teleperm M to PCS 7, every request made to the system technicians has been realized with the shortest and most optimal time expenditure. Please also note our brochure.
