  • Page 15 Operating Operating Operating the device directly Port Switching The current switching state of the output is indicated by the corresponding plain text displays (port LEDs). If the green "on" LED is lit, the port is switched on, if the red "off" LED is lit, the output port is switched off.
  • Page 16 Operating The web page provides an overview of the switching state, energy measurement val- ues, as well as the external sensors, provided that they are connected. When a single port is clicked a panel with buttons to control a single port appear: The Port icon is green when the relay is closed, or red in the open state.
  • Page 17 Operating the time being. In addition to the panel, the Expert Power Control 8316 shows the measured values of the selected port: The ports can be switched manually with the "On" and "Off" buttons. If the port is turned on, it can be turned off by pressing the "Reset" button, until after a delay it turns itself on again.

  • Page 26 Configuration Configuration TCP/IP configuration by DHCP After switching on the device is scanning on the Ethernet for a DHCP server and re- quests an unused IP address. Check the IP address that has been assigned and ad- just if necessary, that the same IP address is used at each restart. To turn off DHCP use the software GBL_Conf.exe or use the configuration via the web interface.
  • Page 27 Configuration defined state after the device is turned on. The delay may last up to 8191 seconds. This corresponds to a period of approx. two hours and 20 minutes. A value of zero means that the initialization is off. Repower delay: When this feature is enabled (value greater than 0), the power port will switch itself on again a specified time after it has been disabled.
  • Page 28 Configuration Enable watchdog: Enables the watchdog function for this Power Port. Watchdog type: Here you can choose between the monitoring by ICMP pings or TCP pings. · ICMP Pings: The classic ping (ICMP echo request). It can be used to check the ac- cessibility of network devices (for example, a server).
  • Page 29 Configuration The option Repeat reset on booting host after x ping timeout has the following pit- fall: If a server, that is connected to the monitored port is in need for a long boot pro- cess (e.g. it is doing a file system check), the server would probably exceed the trip- ping time of the watchdog.
  • Page 30 Configuration If no DHCP server is available, the last IP address is used. However, the DHCP client tries to reach a DHCP server again every 5 minutes. The DHCP request lasts one minute until it is aborted. During this time the IP-address is not accessible! It is therefore essential to deactivate DHCP for a static IP addresses! Use IPv6 Protocol: Activates IPv6 usage.
  • Page 31 Configuration the remote terminal (e.g. the switch). 3.2.2 IP ACL Reply ICMP ping requests: If you enable this feature, the device responds to ICMP pings from the network. Enable IP filter: Enable or disable the IP filter here. The IP filter represents an access control for incoming IP packets.
  • Page 32 Configuration HTTP Server option: Selects whether access is possible only with HTTP, HTTPS, or both. Server port HTTP: Here can be set the port number of the internal HTTP. Possible val- ues are from 1 to 65534 (default: 80). If you do not use the default port, you must ap- pend the port number to the address with a colon to address the device from a web browser.
  • Page 33 Configuration Sever. Use locally stored passwords: Username and password are stored locally. In this case, an admin password and a user password must be assigned.

  • Page 43 Configuration Creating a simple timer If you activate "New Rule: simple Timer" the following dialog is displayed: You set here which port should be switched for which time period, and on which days of the week the rule is active. In this example the period 9:00 to 17:00 is changed to 9:30 to 11:00 compared to the default input mask.
  • Page 44 Configuration You can see here the extended representation of the first rule of the simple timer from the previous example. The action is started every day of every month at 9:30. The weekdays Saturday and Sunday are excluded. An existing rule can be removed with the "Delete"...
  • Page 45 Configuration The switching function can be set in more detail on the "Action PortSwitch" register. Port 1 is switched on. You could extend the rule and switch more ports on or off. Addi- tionally you can set a time for a batchmode in the field after "Between Action1 and Ac- tion 2 : wait", which starts "Action 2"...
  • Page 46 Configuration To change a field in this input mask without changing the state of the other fields, the Ctrl key must be pressed during the mouse click. For this rule, on the "Options" tab, the time period is limited to the range between 5.10.2021 and 5.4.2022.
  • Page 47 Configuration Instead of switching a port, one or more console commands can be executed. These commands are entered in the "Action CLI" register. The "Action Cli" tab can only be se- lected if the option "Perform CLI Cmd" is activated in "Options". Example Switching a Port on a Date If you want to switch on a timer on a certain date at a certain time and switch it off at a later time, you cannot do it directly with a simple timer.
  • Page 48 Configuration which the switching operation is to take place in the "Options" tab. Example blind control You can use the jitter e.g. for a shutter control. In the classic example of a shutter con- trol, you do not always want to raise and lower the shutters at the same time in order to confuse potential burglars.
