Herbid68 Posts: 59 Rating: (9)	I Have : - S7 1212 Ac/Dc/Relay V4.0 - Tia Portal V13 - Intellisys with Modbus TCP/IP via Ethernet (RJ45) - Modslave App - Modscan32 App I build/set up a MB Client in Network (details in attachment). My remote IP Address is set to my Laptop IP Address. By using Modslave App_with my Laptop IP Address configure in it, I can "Send / Change" the value and my 1212 CPU can read it (in Pointer, starting MW100). My Intellisys is fine and all holding register can be read by Modscan32. But when my S1212 CPU try to Read Holding Register of Intellisys, no luck. I have change the IP Address according to the Intellisys one, but still not work. Please someone help? Thx for you all. Attachment Jpg Attach Zip.zip (781 Downloads)

Just add the offset to 40000, which is 1 for your posted example.
