A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The slaves each have identification information. The control apparatus includes executes a first instruction to set specified identification information to each of one or more specified slaves. The control apparatus outputs first error information indicating which slave that the setting of the identification information to which is failed, among the one or more specified slaves.

A communication system includes a communication device functioning as a master device and a plurality of slave devices communicably connected to the communication device via a communication line, the communication device setting a prescribed address in an added slave device based on a position of the added slave device in a topology composed of a plurality of slave devices, judging whether a change has possibly occurred in the topology when the prescribed address is set in the added slave device, if there is an erroneously set slave device whose address was erroneously set, specifying that slave device, when it is judged that a change has possibly occurred, and resetting the address of the specified erroneously set slave device to an original address.

An automation system can generate a unique address for a newly connected device to optimize automated capabilities of the system. An automation system can have a first device connected to a host via a network where the first device has a processor. Connection of a second device to the host as part of the automation system prompts factory information from the second device to be imported with the processor r. A unique address is then generated for the second device with an address module of the processor based on the factory information. A first communication may be sent from the host to the second device using the unique address to allow at least one automated activity to be conducted with the second device in response to the first communication.

A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The slaves each have identification information. The control apparatus includes executes a first instruction to set specified identification information to each of one or more specified slaves. The control apparatus outputs first error information indicating which slave that the setting of the identification information to which is failed, among the one or more specified slaves.

Disclosed is a method for obtaining different addresses by changing internal logic values of a chip through light, the light containing address information is irradiated on a LED lamp bead, and then is transmitted to an IC chip inside the LED lamp bead, and after receiving electric current containing the address information, the IC chip automatically decodes to generate a logical address consistent with the address information carried by the light. Further disclosed is a programming device, including an MUC chip, an optical signal encoding modulator, an amplifier circuit, a light source and a software input module.
