Abstract

PURPOSE:To attain an operation confirming test of extension or remodeling without the entire stop of a system while utilizing advantages of a single bus by adopting two systems of computers for existing and standby systems, providing a computer connection module and a slave station connection module to a master station. CONSTITUTION:A circuit 9 adding a route number of a test control signal is provided to a computer side or a master station and a discrimination circuit of the added route number is provided in a slave station connection module 7. A computer outputting the route number A is referred to as a system A and a computer outputting a number B is referred to as the B system and the system A is used as the existing system and the system B is used as the standby system. In this state, if any remodeling takes place in the slave station No.2 and the revision of application software (8-1m, 8-2m) takes place, a reception route designation signal is outputted from the system A to set the reception enable route number of a slave station No.2 to the system B, the said revision is implemented by the system B, the installation of the slave station No.2 is operated directly and the system B conducts the operation confirming test. Even when, erroneous data such as an error in the slave station number takes place, so long as the route number is kept correct, the slave stations not being an object of test are not controlled in error.
