Important: When the alternate configuration file is used, it is essential that the information in the file be maintained so that it always accurately reflects the configuration of the actual device.
If the file defines a memory type that is too small and there are device points referencing memory locations beyond the range declared in the configuration file, but defined on the device, the point will be incorrectly declared invalid.
If the file defines a memory range that is too large, the result can be an intermittent loss of device communications where the root cause cannot be found based on environmental causes. This will occur if a device point is defined with a reference that is beyond the device memory of the device, but within the range defined in the configuration file.
