Customized Network Data for Configuring a Comms Card
To be able to communicate between a PC running Hevday Interactive Logic, and a Logic Module fitted with a Communications Card (Comms Card), the Comms Card must be set up to use the correct IP address, and Hevday Interactive Logic must be told what IP address the Comms Card is using. These are two separate operations - Configuration | Configure Hardware The Network Hardware Configuration Dialog is used to set up the Comms Card by writing the allocated IP address and other network configuration information into the flash memory of the Comms Card. Configuration | Options | Communications Hevday Interactive Logic is told what IP address to talk to by entering the IP Address in the Logic Module IP Address field on the Communication tab of the Options dialog. The Comms Card stores two IP addresses, only one of which is used at any one time. One is the Fixed IP Address, and the other is the Custom IP Address. The latter can be set to any address you want to use. The Custom IP Address jumper setting selects which of the two addresses will be used.

The Fixed IP address is a private address which does not exist on the public Internet and is intended only for use during set-up operations. It is selected by removing the Custom IP Address Jumper located on the Logic Module. The Fixed IP Address settings are -
If you - make sure that your PC is set up consistent with the above settings, connect from your PC to the Comms Card attached to your Logic Module using a crossover cable, enter the Controller IP Address shown above on the Communication tab of the Options dialog. make sure the Logic Module Custom IP Address Jumper is removed, and cycle the power to the Logic Module, allowing a few seconds for start-up to occur, - your Hevday Interactive Logic software should be able to communicate with the Logic Module. You start the communication session by starting Interactive Logic and clicking the Project | Monitor Project in Hardware menu item, or the equivalent toolbar button. Using the Fixed IP Address is the standard way of gaining access to the Comms Module to set the Custom IP Address to the IP address you want to use for normal use, or to find out what it is set to if you don’t know. If your PC is on a network, and your network administrator can confirm that the Fixed IP Address is not used on the network and agrees to it’s use with the Logic Module, you can communicate during the above setup procedure using normal network cables to attach the Comms Card to a hub or switch on your network. Note: normal network utilization to support simple monitoring operations is well under 0.1% of capacity on a 100MHz network. Once you can communicate with the Logic Module you can set up the Custom IP parameters allowing you to use any other required IP address. Get your network administrator to provide Custom IP Address, Netmask, and Gateway parameter values suitable for your application. An example configuration might be -
To set up the Custom IP Address - Go offline, if necessary, by de-selecting Monitor Project in Hardware. Check that the associated Menu Icon and Button are not depressed. Leave power on and cables in place. Select the Configuration | Configure Network Hardware action, and fill in the new parameter values. When you click OK, the parameters will be written onto the Comms Card for use as the Custom IP. Note that until you replace the Custom IP Address Jumper and cycle the power you will still be communicating using the fixed values. When you see the message -
- you can click Yes and the software will be set up to communicate with the IP address you have just set into the Comms Card. Otherwise, you can open the Communication tab of the Options dialog and enter the IP Address manually. Finally, replace the Custom IP Address Jumper on the Logic Module and cycle the power on the Comms Card and Logic Module. You should now be able to communicate with the Logic Module using the Custom IP values, and if you are using a crossover cable, you should be able to dispense with it and connect to your network with normal network cables. The custom configuration defaults to the following private IP address settings -
If you have a good understanding of your network you may be able to avoiding the use of a crossover cable by using the default Custom IP Address if the Fixed IP Address is unsuitable. Caution: be careful not to put a device onto a network using an IP address the same as another device already on the network. Do get a properly allocated IP address from your network administrator. You can test whether an IP Address is active on your network using the Ping utility invoked from the Command Prompt. Ping is described in detail in your Windows Help system. You should see something like -
