The separa- tion of connection level and electronics sim- plifies maintenance considerably. Flexibility is enhanced because the user can choose be- tween base modules with different connection technologies. The electronic modules are completely inde- pendent of the higher level fieldbus through the use of gateways.

Edition • 2023-07-21T16:15:39+02:00 LED display LED Color Status Meaning D OFF No error message or diagnostics active. RED ON Failure of module bus communication. Check if more than 2 adja- cent electronic modules are pulled. Relevant modules are located between gateway and this module. RED FLASHING (0.5 Hz) Upcoming module diagnostics AO channel Not connected
Edition • 2023-07-21T16:15:39+02:00 Data mapping DATA BYTE Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Output m AO 0 LSB m+1 AO 0 MSB m+2 AO 1 LSB m+3 AO 1 MSB n = Offset of input data; depending on extension of station and the corresponding fieldbus. m = Offset of output data; depending on extension of station and the corresponding fieldbus. With PROFIBUS, PROFINET and CANopen, the I/O data of this module is localized within the process data of the whole station via the hardware configuration tool of the fieldbus master. With DeviceNet™, EtherNet/IP™ and Modbus TCP a detailed mapping table can be created with the TURCK configuration tool I/O-ASSISTANT.
