ISO 11783 standard is supported by the Agricultural Industry Electronics Foundation (AEF) with the aim to promote the compatibility between agricultural products from different manufacturers. Several studies have been used it to develop automation for tractor-implement in industry. The main objective of this paper is to describe an application of ISO 11783 standard for a sprayer with the implementation of a Programmable Logic Controller (PLC). PLC was used as an electronic control unit to provide the integration between the sprayer control and the operator-user by means a universal terminal installed on a tractor. The ISOAgLib was used due its compatibility with the standard. The elements of the universal terminal were designed according to the ISO 11783 standard for agricultural operations of a sprayer. Some essential programming routines and computational tools were implemented based on the ISO 11783 standard that allowed its implementation for an agricultural application.
