Chapter 11 Module Troubleshooting
• Local:7:I.HART.Ch0PVStatus – 16#C0 is good. 0 is bad. This could be a
communication problem or something wrong with device. For example,
with SVStatus, this could mean the device does not support more than one
measurement.
When working with the HART Device Info dialog for troubleshooting, use these
tips:
• HART Initializing means that HART is enabled, but not communicating.
If this persist for 10 seconds after you click Refresh several times, suspect a
HART communication problem or no device.
• Be sure a channel is HART Enabled.
• Be sure values appear, meaning HART communication is okay.
• Check PV values Local:7:I:HART.Ch0PV or Local:12:I.Ch00.Data for
changing numbers.
• Check analog values Local:7:I:Ch0Data or Local:12:I.Ch00.Data for
changing numbers; for the 1756-OF8H module, check that is valid.
• Note that you must have a Logix connection for asset management, as this
delivers the configuration to the module. From the Module Properties
dialog, click HART Device Info to see if it shows information.
The words ‘HART Initializing’ appear here.
Be sure a channel is HART enabled.
