OPPERMANN_T_MOD_I_XXX (FB)

FUNCTION_BLOCK OPPERMANN_T_MOD_I_XXX

Representation

General

This is a temperature transmitter for ventilation ducts and for measurement in pipelines / containers

XXX = 50: 50mm XXX = 100: 100mm XXX = 150: 150mm XXX = 200: 200mm XXX = 250: 250mm XXX = 300: 300mm XXX = 450: 450mm

The Modbus interface and other parameters are configured via NFC and app when a display is present (variant 1). The Modbus interface and other parameters are configured via buttons when a display is present (variant 2).

The measured value offset can be set in 10 steps using a rotary switch on the device. A terminating resistor (120 ohms) can be activated / deactivated.

The Modbus interface is parameterized as follows without any further settings:

RTU 9600 baud 8 data bits even parity 1 stop bit device address = 1
