TROVIS 5500 Automation System TROVIS 5571 Programmable Logic Controller (PLC) Application Freely programmable plants and applications for HVAC systems. Modbus master interface for communication with other Modbus devices (e.g. TROVIS 5576, 5579). Inputs and outputs extendable using Modbus I/O module (accessories) Functions •• Freely programmable according to IEC 61131 using ISaGRAF® Electronics from SAMSON •• Six programming languages –– Ladder Diagram (LD) –– Function Block Diagram (FBD) –– Structured Text (ST) –– Instruction List (IL) –– Flow Chart (FC) –– Sequential Function Chart (SFC) •• Fully graphic, illuminated display with user-friendly operation and plain text display •• Ready-programmed standard applications: –– Boiler control (Kes71) –– Ventilation control (Luft71) –– Heat exchanger sequence control (WT71) •• Ready-programmed default functions/function modules (see ISaGRAF® documentation) •• Over 50 special functions/function modules for extensive program generation in HVAC applications –– Boiler plants –– Heat exchanger sequence control –– Ventilation systems –– Hot water generation –– Heating circuits etc. •• Simple operation in various levels –– Operating level: Application from ISaGRAF® (user configurable) Fig. 1: TROVIS 5571 Programmable Logic Controller (PLC) •• Sensor calibration for each sensor input •• Binary inputs can be added to the error status register –– Information level: Analog inputs, binary inputs, analog outputs, binary outputs and meter bus •• Modbus communication over Modbus master function and Modbus slave function –– Setting level: Date/time levels, Modbus slave, Modbus master, meter bus and universal input type •• Alarm notification by fax or text message •• Individually configurable universal inputs •• Modbus slave connection, also over modem (RS-232) •• Meter bus communication with a maximu

Technical data Electrical connection and installation The controller consists of the housing and the back panel. The electronics are integrated into the housing. The back panel contains the terminal block. Two wires of 0.75 mm2 may be connected to each terminal. For wall mounting, fasten the back panel with the terminal block to the wall. After installing the connecting lines, attach the housing. For panel mounting, insert the housing into the prepared panel cut-out and secure it. After installing the connecting lines, attach the housing. Ordering text Programmable Logic Controller (PLC) TROVIS...

Note: If the universal inputs are used as current or voltage inputs, terminal 13 must be used as ground GND (not terminal 10). Do not connect terminals 9, 10 and 13! Fig. 2: Terminal assignment of TROVIS 5571 Programmable Logic Controller (PLC)
