Bit 15 is the sign bit (SB). Celsius Scale (Table on page 6) The permissible temperature ranges for the characteristic curves are marked in the table on page 6 in the first three columns. The temperatures range from -200°C to +850°C for Pt 100 sensors and Pt 1000 sensors. The sensor characteristic curves for Ni 100 and Ni 1000 sensors range from -60°C to +250°C (DIN characteristic) and from -60°C to +200°C (SAMA characteristic). Temperature values outside the permissible range cause the error code E004 hex of the corresponding channel to be indicated. Fahrenheit Scale (Table on page 7) The permissible temperature ranges for the characteristic curves are marked in the table on page 7 in the first three columns. The temperatures range from -328°F to +1562°F for Pt 100 sensors and Pt 1000 sensors. The sensor characteristic curves for Ni 100 and Ni 1000 sensors range from -76°F to +482°F (DIN characteristic) and from -76°F to +342°F (SAMA characteristic). Temperature values outside the permissible range cause the error code E004 hex of the corresponding channel to be indicated.

IB ST (ZF) 24 PT 100 4/4 8 5080C Error Messages In normal mode, every process data input word contains the temperature value of the corresponding channel. 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. Figure 7 Bit assignment of the error code Checking the Supply Voltage The I/O supply voltage is permanently monitored. If the voltage value is outside the predefined range a module error message is released. The error code E008 hex is entered into the process data input words instead of the temperature values. 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 E002 hex is written to all process data input words. Monitoring Converter Activities A timeout function checks the analog to digital converter (ADC). If the ADC fails, a module error message is released and the error code E010 hex is entered in all process data input words. 15 14 13 12 11 10 9 87 65 4 3 2 10 Bi t Op e n c i r c u i t 50 80C 009 E0 hex R e a d e rro r i n E E P R O M O u t of m e as ur i ng r ange S uppl y v o l t age U S not pr es ent A D C def ec t i v e I n v a l i d c o nf i gur at i o n Re s e r v e d
IB ST (ZF) 24 PT 100 4/4 5080C 9 INTERBUS OUT Process Data Word HIGH and LOW Byte of the First Process Data Output Word 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). The format changes with every new configuration. Possible Configurations in the LOW Byte Figure 9 Possible configurations in the LOW byte The configuration is stored in the non-volatile memory of the EEPROM and is saved when the supply voltage is disconnected. After the configuration is read/written, the 0000 hex 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 15 14 13 12 11 10 9 87 65 4 3 2 10 Bi t HI G H b y t e LO W by t e 50 80C 0 0 7 7 6 5 4 3 2 1 0 Bi t S ens or t y pe 5080C 008 000 - P t 100 001 - P t 1000 010 - N i 100 011 - N i 1000 100 - N i 1000 ( L a n d i s & G y r ) S t andar d 0 - D I N I E C 751 ( P t ) DI N 4 3 7 6 0 ( N i ) 1 - SAM A
