Drawbacks

This uses lots of cycles through channel access gets to fill the array so it is not appropriate where your IOC is busy and your network is not

You must keep the file that specifies the channels synchronized with arrays - it contains the information for correlating array elements with specific channels

An alternative approach could be done in the device support, particularly if all channels are coming thorough the same hardware drivers - then the problem is to coordinate specific hardware channels with particular pieces of instrumentation
