Hi there; I need to access MI area of a V1040 PLC through ethernet. I had written a code that communicate with PLC via serial port before for an another project. Now, I am planning to modify my code to run under TCP. At PC side, I am working with Delphi XE2 using Indy TCP client component. I tested these components on my network with another computers and they work properly. At PLC side, I am using socket 1, port #20256 and Protocol is TCP Slave.. (I think these are default settings of socket 1 so I don't need to add a socket init FB to my ladder, am i right?) PLC info mode says that card is initialized and socket is connected. In addition, when I send a PCOM string, RX counter increases which showed on info mode but the most important thing is missing: There are no replies. The string I sent is a valid PCOM message which returns answer while I sent it over serial port and plus 6 bytes of ethernet header at the leading. Can you please help me to figure out where is my mistake? With my best regards
