###Installation and operation

-* * Installation * *: It is necessary to firmly install the selected terminal board, connect the terminal board connector directly to the PDIO I/O pack, use the threaded bolt next to the Ethernet port to mechanically fix the battery pack, connect one or two Ethernet cables according to the machine settings, and connect the connector on one side of the battery pack to the power supply.

-Operation: When applying input power, the soft start circuit increases the available voltage on the processor board, resets the processor, and turns on the local power supply in sequence. After completing the self-test program, the processor loads application code from flash memory specific to the I/O pack or module type, verifying that the application code, acquisition board, and terminal board are correctly matched. When the match is good, the processor initiates the Ethernet connection by requesting the network address. After the Ethernet is started, the CPU runs the application program, programs the onboard logic, and allows the acquisition board to start working.
