3. Honeywell PlantScape Vista UMB Modbus RTU Interface Application Bulletin by Glenn Heidel INTRODUCTION This document is intended for use as a guide to connecting Honeywell recorder controller devices such as UDC DR DPR UMC VPR or VRX products to a PlantScape Vista system using the Modbus RTU communication protocol This document covers the configuration of the parameters in the PlantScape system related to monitoring or controlling Modbus RTU devices and their associated points It does not discuss hardware configurations wiring or any specifics for devices to be connected In order to monitor and or control points within a Modbus RTU device one must configure a project channel controller and points on the PlantScape Vista system This bulletin serves as an aide to configuring the required information especially regarding the addressing of the different entities to be configured REFERENCE DOCUMENTS 1 Modbus RTU Serial Communication User Manual 51 52 25 66 11 3 99 Revision 1 1 Page 1 of 6 Modbus RTU Serial Communications Link PlantScape Vista PROJECT CONFIGURATION The Quick Builder tool will be used to perform the necessary configurations starting with the project file that contains the configuration data for the generic interface Upon creating a new project file qdb the Quick Builder tool will present a set of tab cards in a window titled Setup Data needs to be entered in three t
