  1. I want to make a connection Modbus TCP slave. For this I use a Arduino libraries. I am using the EK-TM4C1294XL Kit The could enter and take the example they have in the library, the example compiles correctly. Board is connected to a switch and a PC is connected also has disabled the Windows firewall. I use a Modbus TCP client program on the PC to read the records of the kit through Modbus. I can not read the values, tells me it can not connect to the target computer, the connection was denied. If I make ping the IP of the plate answer me well. Someone can help me solve the problem The code
  2. Hi, I am trying to implement Modbus RTU slave over TCP/IP using TIVA Tm4c1294 connected launchpad. The code has been successfully tested using Arduino. However, when I use the same code in energia, the launchpad gets pinged, but Modbus RTU does not work . Is there any library, hardware configuration which I need to change while migrating fro Arduino to TIVA? MgsModbus_test_Slave.rar
  3. Hello, In the case there's no internet and I'm trying to connect to a TCP Server on the CC3200 using the following statement tcp.connect(remote_ip, remote_port) // WiFiClient.connect My program hangs for 30 SECONDS on the above statement. Is there a library file where I can reduce this timeout to something more reasonable like 5 seconds? Thanks!
  4. I try to make a TCP connection between EK-TM4C1294XL and Labview. The microcontroller is the client, and in Labview there is a server. I use Energia's standard functions (like client.connect())., and success to make connection with Hercules. I also success to make connection between Hercules and Labview. But I don't success to make the final connection - microcontroller to Labview. there is a difference between the Energia's functions and the standard?
  5. Hi, I want to implement a code for Modbus RTU over TCP/IP usng TM4C1294NCPDT launchpad. Does anyone know a library which can be used to implement it. Also is it possible to obtain data from a PLC using modbus TCP/IP and send it to a Server on cloud using the same ethernet port? Please help. Thanks.
  6. Hello Everyone, I have used the TCP protocol to connect with a EK-TM4C1294XL, to send and received data, but my Problem, I can not close a connection.
