Dialogue modulesDisplays, input modulesand camera systemsSystem descriptionIntroductionMost machines require an operator for the operating process. Machinestates must be indicated and operator inputs must be processed. The typicalstructure of an operating panel with light indicators, pushbuttons, switchesand – depending on the complexity of the machine – additional pointerinstruments was predominant in mobile machines and installations until afew years ago. Due to the higher requirements for machines and higherexpectations of the users as regards their “mobile workplace” these conceptsare no longer up to date.Depending on the size and complexity of the machine, modern dialoguemodules are fitted with text or full graphic displays and different operatingfields. One unit provides all functions which in case of conventional designscould only be implemented with time-consuming and cost-intensive mountingand wiring of individual components. Due to the individual programmingof the dialogue modules the user only sees the situation-dependentinformation which is relevant. For example the operator gets additionalwarnings and notes for fault elimination only in case of a machine fault. Dueto this situation-dependent display the operating panels have a clearer structureand the operator can concentrate better on the actual work function.Service and maintenance staff also use dialogue modules as an intelligentaccess to the machine. Due to special pages, which can be password-protected,parameters can be changed in the machine controller and the operatingdata stored. The maintenance history of the machine can also be read.Process dialogue monitor PDM360 and PDM360 compactThe dialogue monitor PDM360 is such a user interface. With its powerful32-bit controller and the flexible programming according to IEC 61131-3 itcan be used in almost all applications. Depending on the version the 5.7"graphic display is either a monochrome FSTN or TFT colour display.Due to its robust housing (protection rating IP 67) and the different mountingoptions the unit can be used outside as well as in the cabin. It is designedto be either panel or surface mounted.Communication is done via the CAN bus with the CANopen protocol. Theintegrated interfaces like Ethernet, USB, RS-232 and 2 x CAN together withthe Linux operating system form a universal platform for further networkingand communication with other CAN devices, networks or the PC. Due to theintegrated PCMCIA slot a standardised and flexible interface is available forsystem expansion.PDM360 compact.The central plugof the PDM360.Visit our website: www.ifm.com70
