This sensor type (potentiometer) does not have defined upper limits of the measuring range. Depending on the

gain, however, an open circuit is detected at approximately 400 Ω or at approximately 20000 Ω.

Please note for the potentiometer (No. 13) and linear resistor (No. 14 and 15) sensor types that below 0.8% of the

nominal range (e.g., 0 Ω to 3 Ω for the "linear R: 0 to 400 Ω" type) the diagnostic messages "Overrange" and "Un-

derrange" can be generated.

If the measured value is outside the representation area of the process data, the "Overrange" or "Underrange" er-

ror message is displayed.

Please note for the potentiometer (No. 13) and linear resistor (No. 14 and 15) sensor types that below 0.8% of the

nominal range (e.g., 0 Ω to 3 Ω for the "linear R: 0 to 400 Ω" type) the diagnostic messages "Overrange" and "Un-

derrange" can be generated.

16 PCP communication

By default upon delivery, the terminal is configured accord-

ing to the default settings on page 10. The terminal can be

configured using process data or PCP to suit your applica-

tion.

In PCP mode, the terminal is configured with the "Config Ta-

ble" object.

For information on PCP communication, please

refer to the IBS SYS PCP G4 UM E and

IBS PCP COMPACT UM E user manuals.

The IBS CMD (for standard controller boards)

and IBS PC WORX (for Field Controllers (FC) and

Remote Field Controllers (RFC)) programs are

available for the configuration and parameteriza-

tion of your INTERBUS system.

For additional information, please refer to the

"IBS CMD SWT G4 UM E" user manual and the

documentation for the version of PC WORX

used.
