CHAPTER 4 RS485 PARAMETER GUIDE
Parameter System
Every parameter on the FlowPulse is represented by a unique address and a
value. The parameters consist of two main types: output parameters and
configuration parameters.
Output parameters are read only and cannot be set by the user. Examples
are current flow reading and current signal strength.
Configuration parameters can be queried and set. With each parameter,
there is a factory default value, an associated access level which is required
for setting, and a valid range of values for each parameter.
The parameters are always stored and entered as whole numbers, and the
absolute range is from 0 to 65535, please refer to individual parameter for
individual range.
The naming syntax for the parameters is with a prefix of ‘p’ before the
address. For example, a parameter at address 102 is “P102”. The
value/content of the parameter is delimited by a colon “:”, such that
“P102:20” indicates that the parameter at address 102 has a value of 20.
The terms “parameter” and “register” are used interchangeably as the
parameter number is the actual address of the storage register.
Parameter Access
The parameters on the FlowPulse can be accessed using any of these
methods:
•
The parameters tab on FlowPulse PC (RS232 or RS485)
•
The manual setting terminal on FlowPulse PC (RS232 or RS485)
•
Modbus communication protocol (RS485)
It is recommended that only one method of access is used at any point in
time.
Note: When using methods (b) or (c), the parameter guide in this chapter
should be referred to as the value required may be different from the values
normally entered on FlowPulse PC with method (a).
