What is the Number of simultaneous query from SCADA server that WR21 can handle ?
Could you please provide more detailed information about this question and environment? For example, exactly how would the SCADA server be querying the TransPort? Through what method(s)/protocol(s)? What would be connected to the TransPort in this scenario (and how? serial? Ethernet? something else). The more details the better, so we can better understand your question.
