5.1.9 Digital Output
There are two mode selections for the digital output circuit; one being alarm
mode, and the other being energy output mode. For alarm mode, action of
digital output circuit is controlled by whether the alarm is triggered or not. For
energy output mode, digital output circuits can output various types of energy,
such as import active energy, export active energy, import reactive energy and
export reactive energy. When outputting energy pulses, pulse width can be set
from 20 to 1000ms. The minimum interval between two pulses is 20ms.
Parameter Setting:
Take AXM-IO21 (AXM-IO2 module in logic NO.1) for example.
“DO working mode (10a5H)” register: this register determines the working
mode of DO circuits. If the register is “0”, then DO1 and DO2 will work in energy
output mode. If the register is “1”, then DO1 and DO2 will work in alarm mode.
“DO pulse width (10a6H)” register: when DO circuits work in energy output
mode, this register determines the width of energy pulses.
“DO1 output type (10a7H)” register: when DO circuits work in energy output
mode, this register determines the energy output type for DO1. If this register
is “0”, DO1 outputs nothing. If this register is “1”, DO1 outputs import active
energy. If this register is “2”, DO1 outputs export active energy. If this register
is “3”, DO1 outputs import reactive energy. If this register is “4”, DO1 outputs
export reactive energy.
“DO2 output type (10a8H)” register: when DO circuits work in energy output
mode, this register determines the energy output type for DO2. The value of
this register is defined as the same as “DO1 output type” register.
