HART TAG
Measuring point tagging
• 8 characters
LONG TAG
Long tag: Unique label of the device in the plant (from HART 7)
• 32 characters
Address (Multidrop)
Address range in multidrop mode (HART 5)
Value range: 0 to 15 (0 means no multidrop mode)
Address (HART 7)
Address range (HART 7)
Value range: 0 to 63 (independent of Current Loop Mode)
Information HART 5:
• Address = 0 (Current Loop Mode enabled – Multidrop disabled)
• Address = 1 to 15 (Current Loop Mode disabled – Multidrop enabled)
Current Loop Mode
Only HART 7:
• Independent of the address
• Enabled = normal operation (output current depends on process variable (PV))
• Disabled = Constant output current (like Multidrop HART 5 address >0)
HART Burstmode
Select the
HART Burstmode
submenu
HART Resp.Preambles
Number of preambles to be used for sending
Value range: 5 to 20
Find Device
This option helps with finding a device
The HART master sends HART command #73 to search for the device.
Device answeres with HART initialize Command #0 (long address) - if found
Options:
• Disabled: no reaction HART command #0
• One Time: Once time reaction HART command #0
• Continous: Always reaction on HART Command #0 (long address)
HART Revision
Switch the device from HART 5 to HART 7 or from HART 7 to HART 5.
After the change of HART Revision a device restart is recommended.
Caution: Different driver for tools for HART 5 and HART 7 required.
