I have a question about the EX-RC1 remote I/O adapter. All of the documentation that I have available to me suggests that this adapter can be used to bring in data from expansion devices such as the IO-AI4-A02 to a Unistream PLC. I am aware that data structures for these need to be constructed in Visilogic and ported to Unilogic. However, the documentation further describes the porting of data structures back to Visilogic for deployment in Vision, et al PLCs. This is confusing! Can a Unistream PLC actually work with, assuming the data structures are as per the documentation, expansion devices and utilize the data from those devices in real time?
