Introduction057-248 ISSUE: 1 Page 6 of 501.1 CLARIFICATION OF NOTATIONClarification of notation used within this publication.NOTE: Highlights an essential element of a procedure to ensure correctness.CAUTION! Indicates a procedure or practice, which, if not strictly observed, couldresult in damage or destruction of equipment.WARNING!Indicates a procedure or practice, which could result in injury topersonnel or loss of life if not followed correctly.1.2 GLOSSARY OF TERMSTerm DescriptionApplication The application is the program that allows the DSEM840 to control themachine it is connected to.The Application within the DSEM840 is designed and provided by themanufacturer of the complete machine.Bootloader The Bootloader is the program within the DSEM840 responsible for loadingthe Operating System.CAN Control Area Network. A high-speed data transmission system usedextensively within the Automotive and Off-Highway industries.CODESYS(Previously stylisedas CoDeSys)Integrated Development Environment for programming controllerapplications according to the international industrial standard IEC 61131-3.DSEM840 supports CODESYS V3.5ECU Electronic Control Unit. For example the DSEM840 device.Firmware The Firmware of the DSEM840 is the Operating System of the DSEM840that reads and executes the Application program.FSD Full Scale Deflection. For example 0 mA to 20 mA is the Full ScaleDeflection of a current sink input.I/O Input / Output. For example “The I/O is taken out to an external terminalstrip in the user panel”.IDE Integrated Development Environment. For example the CODESYS V3.5application that runs on the host PC is an IDE.Ixyyy An Input, where x is the connector and yyy is the input number. Forexample IA003 means Input 3 on Connector A.PLC Programmable Logic Controller. Industrial computer used primarily for theautomation of electromechanical machinery.PWMPWMiA digital signal is used to represent an analogue value by using PulseWidth Modulation. The mark-space ratio of a square wave changes torepresent the value.Used for many control applications including proportional valves.PWM= Voltage control.PWMi = Current control.Off-Highway An industrial vehicle used primarily “off road”. For example constructionand farm machinery. A wider interpretation includes on road accessplatforms, emergency vehicles and other industrial machinery, used eitheron the road, or off road.Pin A male or female pin connection in a housing (plug or socket).Qxyyy An Output, where x is the connector and yyy is the output number. Forexample QA002 means Output 2 on Connector C.
