mA Output Parameters (P201 to P219)
P201 mA Output Function (F = 1)
Alters the mA output/measurement relationship. Set independently from P001. This
determines the primary variable for HART/Profibus PA, and should not be changed if
using HART.
Selection can be done locally, or from the Master, using the Primary Variable exchange.
Independent mA Setpoint Parameters (P210 and P211)
Use these features as a reference for calculating the minimum and/or maximum mA
output to any point in the measurement range.
For HART/Profibus PA, 4 mA and 20 mA represent the upper and lower range limits for the
primary variable.
Values
0 manual
1 level
2 space
3 distance
4 volume
9 controlled by HART or Modbus
P201 (mA Function) Settings Response
Level, Space, or Distance
Enter the material level in Units (P005) or percent of Span
(P007) as referenced to Empty (P006).
Volume
Enter the volume in Maximum Volume (P051) units, or as a
percent of Maximum Volume.
Note:
• Ensure the master is off-line with the device when changing this value locally.
Changes will affect the mAmp Output directly, and can cause serious problems if
under automatic control.
• Selection also affects the secondary, tertiary, and quaternary variables.
• 0 (manual) setting is required to utilize P911. Remember to change back to previous
setting after P911 usage.
Note
:
Ensure the % symbol is displayed before entering a % value.
