When an error occurs on a channel or module, a code is written to the corresponding input word that indicates the error cause. If the value E0xxh occurs in the process data this is not a measured value but an error message.

If the voltage value is outside the predefined range a module error message is released. The error code E008hex is entered into the process data input words instead of the temperature values. A timeout function checks the analog to digital converter (ADC). If the ADC fails, a module error message is released and the error code E010hex is entered in all process data input words. Checking the Data in the Non-Volatile Memory The configuration is not stored in the volatile memory of the EEPROM. If the configuration of the EEPROM is invalid, a module error message is released and the error code E002hex is written to all process data input words. 8 5080C IB ST (ZF) 24 PT 100 4/4 INTERBUS OUT Process Data Word HIGH and LOW Byte of the First Process Data Output Word B it 1 5 1 4 1 3 1 2 1 1 H IG H b y te 1 0 8 9 6 7 5 4 L O W 2 3 b y te 1 0 5 0 8 0 C 0 0 7 Figure 8 HIGH and LOW byte of the first process data output word The module can be configured with the INTERBUS master. For this, only the LOW byte of the first process data output word is used. The configuration is valid for all four channels. The process data output words of channels 2, 3, and 4 are not evaluated. During configuration, the measured temperature values continue to be entered in the process data input words of channels 2, 3, and 4 (for channel 1 see note below).

After the configuration is read/written, the 0000hex value must be written to the first process data output word. This causes the first channel to be reset to measuring operation. In the first process data input word, the measured temperature value is transmitted. The default upon module delivery is that all bits of the configuration bytes are set to zero. This leads to the following configuration: Process data format: °C, standard of the characteristic curve: DIN IEC 60751, sensor type: Pt 100, filter frequency: 50 Hz 5080C 9 IB ST (ZF) 24 PT 100 4/4 Assignment of the HIGH and LOW Byte in the First Process Data Output Word The control system transmits a request to the module to read or write the configuration through a corresponding process data output word.
