Javier Galaz Posted January 28, 2022 Report Share Posted January 28, 2022 Hi, I've just joined this forum because I have a problem and I can't find the solution. I've a V700 HMI with a V200-18-E2B Snap-in I/O module. I need to use this HMI as a TCP/IP slave using port 502. I have a ladder that works on V130, but it doesn't work on this V700. could you please help me? ENAMI HMI 2 Solo Modbus.vlp is the trimmed down version of the program, because I wanted to remove every other variable in order to try to debug my program, I believe this should let me read and write every available modbus address (coils, input registers, etc), but when I try to read coils I get 0 bytes read.
