Page 4: Operation
Operation Operation The programmable logic controller (PLC) is freely programmable. The controller is delivered without an executable application in the memory. The application must be developed sepa- ® rately for the desired purpose on a personal computer using ISaGRAF (programming as in IEC 61131-1) and then transferred to the controller. -
Page 5: Display
Operation Display The programmable logic controller has a plain text display. The display is automatically illuminated when entering or setting the controller. After connecting the controller to the power supply, “System is being initialized…“ appears briefly on the display. Should the display not be illuminated or the contrast is too strong/weak, you can adapt the dis- play illumination. -
Page 6: Adjusting The Contrast Of The Display
Operation Note! If no key is pressed for two minutes, the PLC returns to the normal display. The background illumination of the display is switched off automatically. Any settings that have not been confirmed are not saved and must be re-entered. 1.2.1 Adjusting the contrast of the display Activate the editing mode. -

Start-up Note! ® In ISaGRAF , internal variables can be assigned (integer or bool) network addresses. The status or value of the internal variable is written to the associated holding or coil register and can be read or written over Modbus. Important! The PLC application must be reloaded after a cold start. - Page 12 Start-up Confirm the key code.

Page 13: Configuring Universal Inputs
Start-up Configuring universal inputs There are 17 universal inputs, which may be used as binary inputs, analog inputs (0 to 10 V, 0/4 to 20 mA) or as sensor inputs. The hardware must be configured accordingly (sensor ini- tialization). Refer to page 38 for the resistance values of the PTC, Pt 100 and Pt 1000 sensors. You can also configure each universal input separately. - Page 14 Manual operation Select the type of universal input. The inputs are available in the following order: PT100↔PT1000, PT100↔PTC, NI2000, PT2000, PT500, 0 – 10V, BE, 1000 – 2000Ω, PT100, PT1000, NTC, PTC, NI1000, NI200, 4 – 20mA, 0 – 20mA Note! On selecting the universal input types PT100 ↔...

Page 20: Modbus Master Interface
Communication Modbus slave interface in combination with RS-232/RS-485 cable converters (for four-wire bus) Operating the PLC in combination with cable converters requires a permanent bus connec- tion (data cable). The bus line links the devices/control units in an open ring. At the end of the bus line, the data cable is connected to the control station using an RS-485/RS-232 con- verter (e.g. -

Communication Validity The values saved in the PLC, which have been sent by the slaves, have a time-dependent Validity . If the building control station polls the saved data within the valid period of time, the PLC sends the saved data directly to the building control station. However, if the polling to the PLC is outside of this valid time period, the PLC first polls the slaves and then sends these updated data to the building control station. - Page 24 Communication All settings that are made for communication with heat or Meter bus water meters are stored in Settings level > Meter bus > WMZ#1: EN1434/Cont. 250 WMZ#_.

Surge diverters must be installed at the control cabinet inlet. Noise suppression The TROVIS 5571 Controller with SAMSON actuator is interference suppressed according to VDE 0875. If different actuator makes are used, or moreover, further actuators with interfer- ence sources are used in a plant, the operator/supplier of a custom-made plant must make sure that the entire plant complies with VDE 0875 regulations due to the legal obligation of ensuring interference suppression. - Page 30 Electrical connection EB 5571 EN...
