Modbus TCP Communication Request Table
A maximum of 255 requests can be configured in the Modbus TCP Client Request Table.
Notes:
• 10 bytes of the user program area are needed per each request.
• Request execution devices and error status data registers are allocated in the order of request numbers. When deleting a request or changing
the order of requests, the relationship of the request to the request execution devices and error status data register is changed. If the
allocated internal relays or data registers are used in the user program, those device addresses must be updated accordingly.
