Ben,
By default, FieldPoint Ethernet controllers (FP-160X, FP-20XX, cFP-20XX) will allow any number of clients (PCs or [c]FP-20XX controllers) which can read from or write to any of the data points on the FieldPoint bank. Currently, the only ability to restrict the access is on a per computer (IP address of Qualified Domain Name) basis. Thus if you have two computers that are both in the allowed read/write access list, they can both access ALL of the IO points on the modules, no exclusivity is required or enforced. The problem to avoid is that potentially each computer can overwrite the other on the output channels.
