TCP SOCKET NEEDS TO CLOSE and REOPEN FOR EACH MESSAGE
Mariangela Camarda posted a topic in NJ Series / Sysmac StudioGood Morning, I connect using a TCPSocket a remote node with my NJ501-1300. In order to test communication with the remote node I use a telnet communication and send from it messages to the remote node: it work correctly opening the connection and then sending all messages I want; the connection will close only at the end of the communication session. WHAT HAPPEN ON NJ? On NJ Open connection whit remote node; Connection is open; Send first message to remote node; Receive correct answer from remote node; Send another ore the same message to remote node; Receive an unknown command answer from remote node. WHY??? To solve previous problem I need to: Close the open connection; Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; Close connection Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; close connection and so on... Could someone help me to solve this problem opening the connection only once and then close it at the end of the end of communication session?! THANK YOU

wallace113 posted a topic in Allen Bradley / Rockwell AutomationHi everyone, I want to receive signal from E+H flow sensor to Rockwell PLC( module MVI69-HART attached to PLC). I tried to use local 4 which is new local opened when I added successfully MVI69-HART(INT type variable) but it not work. Sensor's monitor display mA values (4mA -> 20mA). Could you please show me how to receive mA signal in PLC software or give me some documents related to this issue? Thanks. Have a nice day. ^^
