I am currently engaged in controlling a specialized pump using Modbus TCP/IP protocol.
After obtaining the protocol from the manufacturer, I successfully programmed the system.
However, despite several days passing, every function seems to be operational except for the execution button, which appears to be related to a specific validation routine within the pump.
Interestingly, the program provided by the manufacturer continues to function flawlessly.
The manufacturer maintains a stance of unfamiliarity with the program I have developed, presenting a perplexing situation.
Is there a method to decipher the packets sent by the Modbus TCP/IP program into hexadecimal code, akin to the process of inspecting COM port traffic with a monitoring program?

You can use Wireshark · Display Filter Reference: Modbus/TCP to debug the traffic.
