Hi. I want to communicate with UDC2500 Honeywell controller with Matlab via Ethernet cable. The UDC2500 setups on the process training system(TE3300) which works with Modbus over Ethernet protocol.This system has a software(specview).I analyse the packets via wireshark.I found that the TE3300 works with TCP/IP,Modbus,Modbus/TCP and some other protocols. Matlab has the command to connect with TCP/IP protocol but it hasn’t any commands for Modbus. I need a library for Modbus and Modbus/TCP. I thanks you a lot if you help me.
