Functioning
The MB-LI-4 module is a four-channel one-way counter. Each
channel is independent and counts the impulses in accordance
with individual settings.
The results are presented in the form of a Number of pulses and
rescaled value in a range from 0 to ~4,29 billion. Reading of the
counter can be reset independently for each channel. Once the
maximum Number of pulses (overflow) is reached, counter au-
tomatically resets and counts from 0.
The module has configurable options of counting pulses with
low or high signal and with leading or trailing edge.
In addition, counting input can be used as a DI digital input with
the ability to read its state.
Reading the values of counted pulses, a rescaled value, ad-
justment of all counting parameters, communication and data
exchange is carried out via RS-485 port using Modbus RTU com-
munication protocol. Power is indicated by a green LED "U" light.
Correct data exchange between the module and other device is
indicated by the LED yellow "Tx" light.
