.1 Easybus Specifications
EasyBus use more friendly language to control the relay module. With "easy to
understand" grammar and similarity to OS command lines, it's extremely easy to work with
it. Read the following materials and you will be ready to go with every detail in 10 minutes.
Not like any other field bus, you don't need to be an expert of automation or learn
programming to use it. This saves time for many people who wants to focus on more
creative works, and they can start to create application with BEM105 immediately, rather
than spend lots of time on learning the old-fashioned and very detailed industry
automation communication protocol before they can really start to do anything.
How to send a correct switch command?
Example - switch on relay channel 1:
K01 = 1;
Example
– set parameter 65, to value 1000:
setpara[65] = 1000;
Example
– read parameter 65 (value will be returned in module reply):
getpara[65] = 1;
