Optimal have automated perhaps 50 Tablet Coaters for multiple major clients all over the world and are thus extremely experienced in with this technology. Systems supplied include machines with semi-automatic and fully automatic controls, new build and refurbished, solvent based and non-solvent based. Systems have ranged from those with very traditional push button controls through systems with HMI interfaces to those with full-blown Client Server SCADA and even DCS.
One specific type of system that we installed was for a blue chip pharmaceutical client and their requirement was for a fully automatic system and used a Siemens S7 400 PLC at its heart with GE iFIX client server SCADA at the top end. It had a full and comprehensive recipe system plus all the necessary CIP functionality. Batch reports were generated for use as part of the product’s life cycle documentation, and all salient parameters were recorded in the SCADA’s database for future use and process optimisation.
