No chance for bacteria:
KS 98 and KS 98plus used in pasteurizing equipment

Pasteurizing plays an important role in many processes of the foodstuffs industry.During pasteurizing, the process-dependent "pasteurizing value" (PV) must be maintained accurately, in order to ensure reliable results.

Previously, the process was controlled by means of a PLC with integrated loop-control software. Computation of "PV" in the PLC requir ed considerable programming expense and places a high working load on the PLC, because the computation is complex and includes natural logarithms. Moreover, a local operating terminal is necessary.

The multi-function units KS 98 and KS 98plus now enable the manufacturer to install a single device that provides loop control, sequencing, visualization, and operation of all the process values concerned.

The KS 98 computes "PV" quickly and accurately, and handles the complex control tasks. Due to its graphic display, no local operating and visualization terminal is required. Similarly, the PLC functions and the communication with supervisory systems via a field bus (PROFIBUS-DP, INTERBUS) are standard features of the KS 98 and the KS 98plus.

For the manufacturer, this solution has two main advantages: Firstly, the hardware costs are greatly reduced because a single unit replaces several PLC versions with operating terminals. Secondly, the consistent automation concept enables the pasteurizing equipment to be installed even in small dairies. Larger plants are fitted with the KS 98plus and its flexible I/O extension facilities.

Furthermore, the engineering is quicker and simpler, because both controller versions are matched to the required task by means of the same convenient, graphical engineering tool.
