1. Address Settings The AnyNET I O platform allows you to connect up to six niam lt modules to a single network connection in what we call an AnyNET I O Stack The DIP switches behind the front panel cover are used to set the address of the module within the AnyNET I O Stack A module with a network interface such as the ANE2E for Ethernet networks com municates with the host and must have an address of zero This address is set by having all of the DIP switches in their OFF position If you are using a single module then it must have an address of zero The remaining modules in the stack should have their addresses set to their posi tion in the stack by setting the corresponding DIP switch to its ON position Figure 1 5 shows the correct address ing for three modules The module on the left is an ANE2E and has its address set to zero The remaining modules can be ANE2 modules with or without network interfaces and their addresses are set to one and two NOTE gt If an ANE2 with a network interface has its address set to any value other than zero its net work interface is disabled This allows you to use multiple modules with network interfaces in a single AnyNET I O Stack STATUS 1 2 Channel SSI Input 2 Channel SSI Input 2 Channel SSI Input Figure 1 5 ANE2 Front Panel Status LED s As shown in figure 1 5 there are two Status LED s on

The Preset Value parameter gives you the ability to offset the Data Value When you preset the Data Value the ANE2 calculates an internal offset The internal offset is the value needed to make the Data Value equal to the Preset Value The default Preset Value is zero Its range depends on the value of the Full Scale Count Parameter gt Ifthe Full Scale Count is zero the range of the Preset Value is 268 435 455 gt Ifthe Full Scale Count is not zero the range of the Preset Value is 0 to Full Scale Count 1 The type of internal offset that is generated when you preset the Data Value is also affected by the value of the Full Scale Count gt If the Full Scale Count is zero the internal offset is a linear offset The range of values that you will see in the Data Value will be shifted by the amount of the internal offset For example without a preset applied the Data Value ranges from 0 to 100 If you are at position zero and apply a Preset Value of 1 000 the Data Value will now range from 1 000 to 1 100 gt If the Full Scale Count is not zero the internal offset is a circular offset This offset shifts the zero point of the Data Value It does not change the range of values that you will see from the Data Value Programming this parameter does not change the Data Value There is a separate command for presetting the Data Value to the Preset Value This command uses the Apply Preset to Data Value bit in the Network Output Data as descri
