MODBUS SUPERVISION PROTOCOL 12620101AN Rev04 Page 3/14 1INTRODUCTION The NO-BREAK KS machine can be equipped in option with a Modbus communication protocol to allow one to monitor the status and alarms related to the operation of the system. 2PROTOCOL AND WIRING. 2.1INTERFACE There are three possible variants for the Modbus Communication Protocol: ASCII, RTU or Ethernet. Please check which variant was ordered with your machine to configure your Modbus master. 2.1.1Modbus ASCII or RTU Connection : -RS-485typeinterface(screwterminals)insidethecontrolpanel,terminalsMDB(-),/MDB(+)andPGND (shield). -EachcontrolpanelCOPhasitsownmodbusprotocol,pleaseensurethatallsystemsonthebushavea different Modbus address. 2.1.2Modbus Ethernet (TCP/UDP) Connection : -Ethernet type interface (RJ 45) on a Modbus TCP/IP RTU converter inside the control panel or the DIP. -Depending on the site configuration,oeithereachcontrolpanelCOPandDIPhasitsownmodbusTCP-RTUconverter:oneIPaddress (dynamic per default or static) must be available for each control panel. ooronlyonemodbusTCP-RTUconverterisplacedintheDIPandallthePLCs(COPs and DIP)canbe accessed through this unique converter: only one IP address (dynamic per default or static) must be availableinthiscase.AllCOPsdatabasesareaccessiblethroughthatsingleentrypointonthesub Modbus RTU network. 2.2PROTOCOL 2.2.1Modbus ASCII or RTU: -Slave station address: 1 (default when the unit is shipped). The slave station number can be changed through the human/machine interface. -Communication parameters: 9600 bps, 8 bits, No parity, 1 stop bit (default). These parameters can be changed through the human/machine interface. -The remote supervisor must be configured as master. The slaves answer Modbus read requests only. Write requests will return an error code 41 (Rejected). This document is the property of EURO-DIESEL S.A. and may neither be disclosed nor reproduced without written authorization. Information provided is believed to be correct and reliable. EURO-DIESEL S.A. reserves the right to amend this document without notice.

MODBUS SUPERVISION PROTOCOL 12620101AN Rev04 Page 4/14 2.2.2Modbus TCP/UDP: -Slave station IP address: DHCP (default when the unit is shipped), or fixed (configurable). TheModbusIPaddresscanbechangedthroughathird-partysoftware,refertoseparateleafletin documentation files. -Communication parameters: TCP or UDP mode, port 502. The remote supervisor must be configured as master. The slaves answer Modbus read requests only. Write requests will return an error code 41 (Rejected). 2.3RESPONSE TIME Typical answer time to a request: < 500 ms 2.4REMARKS Please take the following remarks in consideration when programming your Modbus master: -in the PLC, data address begin at 0. Should the supervisor begin its data address at 1 all the addresses mentioned in this document have to be shifted of one unit. -this document describes all NO-BREAK KS-Vision existing data points and alarms. Some alarms or measures may not be present or active for a particular machine/installation. - in case of special functionalities requiring additional information available through the modbus interface, a separate document with the non-standard data will be issued. -for a parallel installation of n machines, the same data base is available in each of the machines, only their Modbus address is different. 3DATA ADDRESS INSIDE THE PLC In the following chapters, the following notations are used: -TheletterFstandsforFlag,i.e.adigitalinformation.TheModbusmastermustuseModbusfunction01 (Read Coils) to gather that type of information. -TheletterRstandsforRegister,i.e.asignedintegercodedon16bits.TheModbusmastermustuse Modbus function 03 (Read Holding Registers) to gather that type of information. -The addresses after F or R are given in decimal. 3.1DIGITAL DATA BASE 3.1.1KS status F 600 System OK F 601 Automatic monthly test F 602 Diesel automatic test F 603 Mains present and in tolerances F 604Normal mode F 605 Emergency mode F 606Manual by-pass open/closed This document is the property of EURO-DIESEL S.A. and may neither be disclosed nor reproduced without written authorization.
