4 Programmable parameters
The MFC-400/I-IAC and MFC-400/I-IDC were developed to provide the user with the
greatest possible flexiblity, such that all supervision and configuration can be executed
on-site or remotely through the existing communication channels.
We define all user-configurable parameters below.
4.1 General parameters
Parameter
:
Sampling Factor
Options
: 1 to 1000.
Description
: ratio between the current displayed by the MFC-400/I-IAC or MFC-400/I-
IDC and the sampled current.
Parameter
:
AC frequency
Options
: 60 Hz, 50 Hz.
Description
: input current frequency (only applicable to the MFC-400/I-IAC).
4.2 Current outputs (option)
Parameter
:
Output Scale
Options
: 0-1, 0-5, 0-10, 0-20, 4-20 mA
Description
: refers to the various configurable current loop scales.
Parameter
:
Full Scale
Options
: 0.01 to 10.00 A, in increments of 0.01 A.
Description
: input current corresponding to the current loop’s full scale output. For
example, if
Full Scale
= 5.00 A and
Output Scale
= 4-20 mA, the current loop output will
be 4 mA for a 0.00 A input and 20 mA for a 5.00 A input.
4.3 MODBUS protocol
Parameter
:
Baud Rate
Options
: 9600, 19200, 38400, 57600, 115200 bps.
Description
: baud rate for the RS-485 link.
