The paper deals with utilization of Ethernet interface of microcontroller MC9S12NE64 in automatic
control of hide soaking process. Microcontrollers are widely used in small or medium size technological processes.
Microcontroller is usable for controlling the process described in this paper. The presented algorithm was developed to
optimize the soaking process and prevent structural damage of hides that occurs while the hide is sunk and washed in
plain water. Such damage is caused by large osmotic pressure that tears the fine structure of the hide. The algorithm
was fully implemented into the microcontroller which controls the whole process. The Ethernet interface was used for
interconnection with a computer. Web server is also part of the microcontroller so that the whole application is saved
in the microcontroller`s flash memory. The computer only requires installation of a common web browser to provide
successful communication with the microcontroller.
