  • Page 12: Introduction

    Introduction Introduction The ML77B module uses the internal bus (link) to access measured values from other system modules and “hand them over” to the Profibus. The Profibus output (e.g. taring, zeroing, clearing peak value stores, predefining limit value levels) is transmitted to the respective amplifiers via the internal serial interface in the form of single commands.
