i am trying to make a modbus TCP communication between omni FC 6000 and Siemens PLC s7-300 (PN), But i have a problem when i was trying to access the 32-bit registers like registers number 5109, and 5110. I figured out the custom data packets can help me but i cannot understand how it work and how i access this packets, and if i can arrange multiple of 32-bit and 16-bit registers in one data packets and access all of them as a multiple of 16-bit registers and what address this data packets will took it?
