5. Conditions for remote control
The device you intend to use in remote control can be in different control states:
1). It is currently controlled by the analogue interface (where featured) and thus not controllable via digital interface.
2). It is in local state (display shows “Local”) and thus locked from remote control in terms of writing to it.
3). It is freely accessible. Then the PC can take over remote control.
If the situation is according to 3), the device will accept remote control commands (write access). Otherwise, only the
actual values of voltage, current and power are read and displayed (resistance is calculated). In order to set the device
into remote control, any other external control or local state has to be canceled manually at the device. Afterwards, it
can be set to remote control with button “Remote on” in the app “Terminal” (see below). Details about device states ng
can be found in the user manual of the device.
5.1 Controlling multiple units at once
Since version 1.52 of this software there are two separate ways to control and monitor multiple devices:
 Control and monitoring in separate windows, one for each unit (feature included)
 Control and monitoring in one window (“Multi control”) (not free of charge, optional)
Both ways work differently. The separate handling in single windows for each unit is only recommended for a small
number of devices, let’s say up to 5. When wanting to control and/or monitor more units, the overview would be lost with
that many windows open at the same time. This is what to use “Multi control” for, which offers the option to have up to
20 units of different devices in a clear overview in a single window. One of the primary functions of “Multi control” is to
set values or status of output/input on the selected device at the same.
Note: the feature “Multi control” is included in EA Power Control from version 1.52, but cannot be used without prior
installation of a license code which is not free of charge. For more information refer to 11. License Management and 12.
App „Multi Control“.
Single window operation mode allows for up to 10 devices at once. This can be achieved by opening the control app
“Terminal” for every unit and switch between the windows. Those windows can be arranged at will on the PC screen. All
units and windows work separately, there is no interconnection. More details below.
Note: Remote control or even just monitoring devices on their actual values requires constant communication. The more
devices are controlled/monitored, the more communication traffic will be generated and depending on the overall load
of the PC with background tasks and other software running, EA Power Control might slow down because of too little
CPU time. This can result in delayed response to buttons clicks or delayed refreshing of actual values and status.
