Modbus accessible parameter definitions
For definitions of the Modbus accessible parameters shown in Table 3–2 below.
For more detailed information, refer to “Measurement and Control
Parameters Defined” on page 2-15.
•
% ConvFactor 02 : Sets a custom conversion factor when the
parameter Concentration Unit = 2 (%) and this value is greater than
0.0. When it is equal to 0.0, the default conversion factor is used.
• 2 Way Com Port : Sets the port that allows two-way
communications, including Modbus and the diagnostic protocol.
• 4-20 mA Alarm Action : Determines the current loop state upon an
alarm condition.
• 4-20 mA Input Value : The current value of the 4-20 mA input for
pipeline pressure in mA’s.
• 4-20 mA Output Value : The current value of the 4-20 mA output
for concentration in mA’s.
• 4-20 mA Val Action : Sets the operation mode of the 4-20 mA
current loop during validation cycles.
• Alarm Flags : Bitwise value identifying the status of each individual
alarm in the analyzer, as listed in Table 3–2 below.
