Abstract
A checksum negotiation unit selects as a candidate polynomial, a candidate for a generator polynomial to be used in communication between a safety master device and a safety slave device from a plurality of polynomials. A communication cycle verification unit determines whether or not a calculation using the candidate polynomial is completed in each of the safety master device and the safety slave device by a predetermined deadline. The communication cycle verification unit designates the candidate polynomial as the generator polynomial when it is determined that the calculation using the candidate polynomial is completed in each of the safety master device and the safety slave device by the deadline.
