Click on the “Connection” tab to be able to connect to the Controller. The following screen will then be displayed:
There are two ways to communicate with the Controller (CTD):
1. over Ethernet: Only if the CTD has an Ethernet port – CTD10, CTD40, CTDMax, CTD01Em, CTD01E, CTD01E+, CTD02E, CTD03E.
2. via USB: possible with the following 'older' CTDs: CTD01Em, CTD01, CTD01E, CTD01E+, CTD02E, CTD03E
If you wish to communicate via USB, click on the USB option in the setup screen. Make sure that the selected communication ports are set (default from COM1: to COM8:)
There are 2 ways to connect to the CTD via an Ethernet cable:
1. If you are connecting to the CTD through a router, you must connect the controller to the router using a straight Ethernet cable (supplied with the CTD - usually yellow). It is important that the Ethernet cable is plugged in before the CTD is powered up. You will also need a straight cable to connect your computer to the router. If you have a wireless router, you can establish a wireless connection with your computer to this router.
2. If you connect the ethernet port of the CTD directly to your computer, a straight ethernet cable will suffice in most cases. However, if the computer is a bit older, a crossover network cable (not included) is required. It is important that the Ethernet cable is plugged in and the computer is powered before the CTD is powered up.
With a correct physical connection, the left LED on the Ethernet port will light up green and the right LED will flash green when there is data traffic.
To operate the device via Ethernet, an IP address must be assigned.
When a device is powered up, it will only search for an IP address if there is already a good physical connection. When the CTD is connected via a router, this router has integrated DHCP, which ensures that each connected device is given an IP address.
To assign the correct IP address to the CTD, uncheck the USB and check the Ethernet option in the setup screen, then click "Search for CTD’s and settings…".
When you click on "Search for CTD’s and settings…”, the System Manager will search for CTD’s in your network via UDP broadcast. If the table remains completely empty, select the network interface in which the controller is located. When the desired CTD has been found, double click on the desired line to establish communication. If successful, the settings screen disappears, the correct IP address is entered in the "IP address or host name" field of the setup screen and the connection is established.
If you connect through a router, you will get an IP address that usually starts with 192.168.
When you connect to the Controller directly from your computer (without a router with DHCP server), you will get an IP address that starts with 169.254
The (Not-)connected status is always visible at the top right. Clicking on this icon connects or disconnects the USB/Ethernet connection to the controller.
ATTENTION!!
- The local communication of the System Manager always takes place via port 8445, which is entered in the "setup" window, in the "Port" field next to the IP address.
Remark: Connect the network cable first, then power up the controller to request an IP address via DHCP. Of course, direct connection to a PC is possible, in which case a crossover cable is sometimes required (purchased separately at an IT specialist store).
Remark: you can give a fixed IP address to the Controller. In the TCP/IP Settings screen you can enter the desired IP address and then click on “Set IP / Gateway / DNS”. This is usually more interesting because in the event of a power failure, the CTD and other IP address can be assigned. Be sure to use an IP address that is not yet in use. If necessary, use the “PING” button to test this.
- To set a password for the Ethernet connection:
The controllers are delivered without a password. When the controllers are connected to the Internet and you want to make changes over the Internet, a password must be set for security. To set a password, enter the old password and the new password twice and send it to the interface. This is done via the screen shown above; when you have entered a password twice, click on the option "send new password to the current connection".
