Comprehensive diagnostics for fieldbus physical layer andpower supply

Plug-in Module for the FieldConnex Power Hub Precise measurements through passive circuits For commissioning, online monitoring and troubleshooting For FOUNDATION fieldbus and PROFIBUS PA Installation in Zone 2/Class I, Div. 2 System state and fault indication via LEDs Display of data in the safety of the control room Automatic setup of diagnostic system Full software integration into DCS and PAM possible

Function

Designed as a plug-in module for the FieldConnex PowerHub, this Advanced Diagnostic Module (ADM) is acomprehensive measurement tool for the physical layer of upto four fieldbus segments. It's passive input circuits leave thephysical layer untouched for exact data. The ADM detectsgradual or sudden changes and helps trace even intermittentmalfunctions.The ADM supports commissioning, online monitoring andtroubleshooting. It can be integrated tightly into the DCS andPAM via a separate diagnostic bus, making the fieldbusphysical layer itself a managable asset. Configuration toolsautomate setup of the ADM and of selected DCS.The Diagnostic Manager is the software for display andoperation from the safety of the control room. TheProfessional Edition provides powerful functions and wizardssimplifying and automating work procedures: Embeddedexpert system data historian and a built-in oscilloscope areincluded. (see datasheet DTM-FC.AD*).

Software User Interface for monitoring up to or including 100 fieldbus segments: Diagnostic Manager, Professional EditionDTM-FC.AD

Software User Interface for monitoring more than 100 fieldbus segments: Diagnostic Manager, Professional EditionDTM-FC.AD.1

KT-MB-GT2AD Diagnostic Gateway

Expert system Built-in expert system interprets behavior of each segment based on rules and givespointed information in clear text. Precisely diagnosis causes and suggests remedies,which are easy to understand.

Supply input voltage The supply voltage of the primary and secondary input is measured in a range of0 V ... 40 V.

Segment power redundancyintegrity

The health of the primary and backup fieldbus power supply is monitored. Mismatch ofredundancy pairs is detected and causes an alarm.

Fieldbus voltage The segment voltage is measured in a range of 0 V ... 35 V.Fieldbus current The current feed into a fieldbus segment is measured in a range of 0 A ... 1 A depending

on the used power supply.Unbalance detection A capacitive or resistive short between any fieldbus wire and shield is measured and

given in a range between -100% ... +100%.(-100% = short against - wire, +100% = short against +wire)

Termination Over- and Undertermination are detected and reported.Signal level Node specific signal levels are measured in a range of 0 V ... 2.5 V.Jitter Jitter is a measurement for the timing of each bit. Each component connected (power

supply, field instrument, cable, ...) to the segment influences jitter. It is an excellentindicator for segment health. The jitter is either segment- or device-specifically measuredin a range of 0 sec ... 8 sec.

Signal polarity For each node the polarity of the signal modulation is given.Noise measurement Noise is measured in a frequency range between 100 Hz ... 140 kHz. Noise measurement

is node-address-specific in order to detect device-specific noise.Communication errors statistics Segment-specific error counters, e. g. for CRC errors, framing errors.Oscilloscope function The built-in oscilloscope is a powerful tool for signal voltage behavior analysis. It allows

for analysis of specific frames and occurring communication errors. Trigger conditions, ase. g. different frame types, CRC errors, framing errors are either node-address-specific orunspecific. The frame contents detected in the sampled period are analyzed and shown.

Live list generation A list of all connected devices and additional status information is generated. The ADMdetects initial connection of a device to a segment in operation. A message reminds theuser to re-run the commissioning wizard.

Alarm management For all measured values, either segment- or node-specific, alarm limits exist. In addition,warning limits can be defined. When these limits are violated, alarms are generated.

History/trending function For up to 2 years, segment- and node-specific physical layer values can be stored andtime stamped in the Diagnostic Module, so trending analyses are possible over longerperiods of time.
