The percentage tolerance values refer to the respective positive measuring range final value. Unless stated other- wise, nominal operation (nominal voltage, preferred mounting position, default format, default filter setting, identi- cal measuring range setting for channels) is used as the basis. The tolerance values refer to the operating temperature range specified in the tables. The operable range outside this range is not taken into consideration. Please also observe the values for temperature drift and the tolerances under influences of electromagnetic inter- ference. The maximum tolerance values represent the worst case measurement inaccuracy. They contain the theoretical maximum possible tolerances in the corresponding measuring ranges as well a the theoretical maximum possible tolerances of the calibration and test equipment.

The data contains the offset error, gain error, and linearity error in its respective setting (4-wire technology). See separate table for additional temperature values and possible tolerances under EMI. All errors indicated as a percentage are related to the positive measuring range final value. The data is related to nominal operation (preferred mounting position, Us = 24 V, etc.) using 4-wire operation for RTD inputs. The maximum tolerance values represent the worst case measurement inaccuracy. They contain the theoretically maximum possible tolerances in the corresponding measuring ranges. The maximum tolerances of calibration and test equipment, which are theoretically possible, have also been taken into consideration. This data is valid for at least 24 months.

Even under EMI indicated above is the accuracy class of 0.1 retained. Additional low tolerances may occur due to the influence of high-frequency electromagnetic interference caused by wireless transmission systems in the near vicinity. The values specified refer to nominal operation in the event of direct interference to components without addi- tional shielding such as a steel cabinet, etc. The above mentioned tolerances can be reduced by providing further shielding measures for the I/O module (e.g., use of a shielded control box/control cabinet). Please refer to the recommended measures in the IL SYS INST UM E Inline system manual. Activation of the "open circuit detection sensitivity" (ODS) function is possible with firmware version 1.10 or later. When activating this func- tion, please observe the “Notes on diagnostic behavior in the event of an error” on page 33.

High current flowing through potential jumpers UM and US leads to a temperature rise in the potential jumpers and in- side the terminal. To keep the current flowing through the potential jumpers of the analog terminals as low as possible, always place the analog terminals after all the other termi- nals at the end of the main circuit (for the sequence of the Inline terminals: see also IL SYS INST UM E user manual).

13 Process data
The module has five process data words. The first word is the control word, which is used to execute all actions. As confir- mation for an action, the first input word contains a partial copy of the control word. The error bit indicates whether a com- mand was carried out without errors. For the command codes 4x, 5x, and 60, a set error bit indicates an invalid configuration. For the commands used to read the measured values (command codes 00 ... 09), the error bit represents a group error mes- sage. If the error bit is set, there will be an error message on one or more channels. The terminal has five process data words and one PCP word. Figure 9 Order of the PCP word and the process data words
14 OUT process data words
Five process data output words are available. Configure the terminal channels via the OUT process data words OUT1 and OUT2. In this context, the output word OUT1 contains the command and the output word OUT2 contains the parameters belonging to this command. Configuration errors are indicated in the status word. The configuration settings are stored in a volatile memory. If you change the configuration, the message “Measured value invalid” appears (diagnostics code 8004hex), until new mea- sured values are available. Please note that extended diagnostics is only possible if the IB IL format is configured as the format for represent- ing the measured values. As this format is preset on the terminal, it is available as soon as the voltage is applied.

14.3 Parameters for configuration
The module can be configured either via process data or PCP. The error code “Measured value invalid" is output during con- figuration. If the configuration is invalid, the error bit is set in the status word. The configuration is only stored in a volatile mem- ory. The first output word must contain the command, the second output word must contain the configuration value. Default settings are marked in bold.

The terminal only needs to be configured if the channels are not to be operated with the default values (see “Parameters for configuration” on page 17). You can either configure the terminal via process data or via PCP and transmit analog values accordingly.

24 Notes on diagnostic behavior in the event of an error
24.1 Diagnostic behavior in the event of an error with ODS = 0 or ODS = 1
The following error states are detected and indicated by the terminal itself. The errors are partly represented via the process input data and/or the corresponding diagnostic LEDs on the terminal.
24.2 Diagnostic behavior in the event of an error with ODS = 3
For applications with particularly high EMC requirements (significantly higher than the standardized limit values) the ODS function can be set to value 3. This deactivates the open circuit detection function and allows for error-free measurements even under particularly high EMI. The diagnostic system detects and reports single interrupted sensor wires or multiple interrupted sensor wires as well as completely disconnected sensor cables, see 24.1 to 24.4. Malfunction/error Indication in the process data or other messages Diagnostic and status indication UL (7.5 V) is missing None, bus error No LED is on. Measured value is above the valid mea- suring range (e.g., 500 Ω at Pt100 input). 8001hex, overrange Error bit set in the first process data input word. The LED of the relevant channel (1 ... 8) is red. Sensor connector is not plugged in and/ or the sensor cable is completely inter- rupted. 8002hex, open circuit Error bit set in the first process data input word. The LED of the relevant channel (1 ... 8) is red. Measured value invalid (e.g., during the reconfiguration of a channel) 8004hex, measured value invalid Error bit set in the first process data input word. The LED of the relevant channel (1 ... 8) is temporarily red. U ANA (+24 V) is missing or failure of in- ternal I/O voltages. I/O error message is triggered. The D LED is green and flashes at 2 Hz. Internal component faulty 8040 hex, self diagnostics Component error and error bit set in the first process data input word. Measured value is below the valid mea- suring range (e.g., 5 Ω at Pt100 input). 8080hex, underrange Error bit set in the first process data input word. The LED of the relevant channel (1 ... 8) is temporarily red. Malfunction/error Indication in the process data or other messages Diagnostic and status indication Sensor connector is not plugged in and/ or the sensor cable is completely inter- rupted. 8001 hex, overrange Error bit set in the first process data input word. The LED of the relevant channel (1 ... 8) is red.

During this time the measured values are either rising or falling.
