INTERBUS IN Process Data Word

Figure 6 Sequence of the four INTERBUS IN process data words in the INTERBUS ring and

representation of the bits of a process data word

Bit Assignment of the INTERBUS IN Process Data Word

The 16 bits of the calculated measured value (16-bit ADC resolution) are used according to the

following table. 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 E004hex 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 E004hex of the

corresponding channel to be indicated.

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 E008hex 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 E002hex 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 E010hex

is entered in all process data input words.

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 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,
