My friend, Client is the role to actively send or receive the data, it is MASTER . Server is role passive, it is SLAVE. Please see the link www.simplymodbus.ca/TCP.htm
So I need to split the string and send it separately? Addition, if I have the Siemens as a Client, which tag type (like 16#00C1) can transmit alphabet ？ Thank you so much in advacne!
