Master is a device that is “The Boss” of the communication. The purpose of the Master is to mea-
sure a Grid status, DC voltage and by the DC Voltage it counts a reference value of the DC. By the
Grid status master works with Grid standards. Master sends values to slaves and TA70 touch panel.
The TA70 touch panel is response to these values and commands the slave units to ON or OFF
states, if there is any. Usually in a device combination there are more than one similar devices con-
nected to each other. In these cases one of the devices must be set to be as master and the rest as
slave.
Slave is a device that is a “listener” of the communication. The purpose of the Slave is to listen val-
ues and commands coming from the Master device.
All units are send status information to the TA70 touch panel.
When the system is stopped there is an arrow indicating which unit will start as a master next time.
