ensures a stable LAN connection even with an unstable WiFi AP
The PowerCable Modbus 101x smart power extension cable is designed for semi-industrial applications, where the Modbus/TCP protocol is the de-facto M2M standard. Modbus/TCP is supported by a majority of PLC, RTU, HMI, robots or smart home / smart building applications.
The metered power socket can be controlled over Modbus/TCP as a “coil” or with commands such as “Short ON”, “Short OFF”, “Toggle”. All measured values can be read over Modbus/TCP.
To ensure a basic level of security, the built-in IP FILTER can be used to limit the range of IP addresses allowed to access the device over Modbus/TCP.
Application of M2M protocol Modbus/TCP
Modbus/TCP was originally designed for communication between a PLC (an industrial controller) and its sensors and actuators. It is considered an industry-standard, and it is very wide-spread thanks to its simplicity. There are many test utilities available and various smart building systems or audio/video presentation systems support it, too.
ZCS (Zero Current Switching)
PowerCable Modbus connects or disconnects its 110/230VAC output using a relay when the immediate current value is close to zero.
IOC (Independent Output Control)
Output control is completely independent of the WiFi communication subsystem.
it is important to set the power outlet status immediately after the device is powered on (or the power is restored after a failure)
PowerCable Modbus 101x measures the most important electrical parameters. All measured values are shown in the device web interface and can be read over Modbus/TCP. Use the device e.g. as a WiFi power meter.
Output power [W]
TPF (True Power Factor)
Mains grid frequency [Hz]
Quick WiFi connection setup
NETIO PowerCable creates a WiFi network that you connect to with your PC or mobile phone.
It then scans for WiFi networks in the vicinity, and lets you choose from a list and type the password
NETIO PowerCable then confirms the connection to the network and displays the assigned IP address
NETIO PowerCable devices can be discovered in the LAN using the NETIO Discover tool.
PowerCable Modbus 101x
NETIO PowerCable Modbus 101x is a smart WiFi power socket by NETIO products. The output smart power outlet can be turned on/off over a web interface. The web interface also shows measured electrical values (V, A, kWh, W, Hz, TruePF). PowerCable Modbus 101x supports the industry-standard Modbus/TCP protocol for M2M communication. This protocol makes it possible to measure energy consumption and control the output from PLCs, SCADA systems, smart home applications, and so on.
PowerCable can be used for metering or on/off switching of computer power supplies up to the electrical socket rating (10/16A according to version).
As a unique feature, the metered power socket supports ZCS (Zero Current Switching). This makes it possible to connect capacitive loads (switching power supplies) or inductive loads (transformers, motors) to the PowerCable.
The output can be switched on with a delay, in order to avoid circuit breaker tripping when power is restored after an outage. The metered power outlet can be switched on/off at any time with the button on the device (press 3 times).
PowerCable Modbus connects to the network using WiFi (internal antenna). The initial WiFi connection is very simple: PowerCable works as a WiFi AP, searches for available WiFi networks and asks the user to select from them.
The web interface is used to configure the product and switch the output on or off. Measurements of immediate current [A], voltage [V], energy consumed [Wh / kWh], grid frequency [Hz], input power [W] and TPF (True Power Factor) are also displayed in the web interface and can be read over the Modbus/TCP M2M protocol.
