PROBLEM TO BE SOLVED: To simultaneously output plural announcement messages to various kinds of PLC, according to an operating state. SOLUTION: A communication protocol through an exclusive network 5 between a PLC 3 and a programmable display 2 is converted into a communication protocol through a common network 4 between the programmable display 2 and a personal computer 1, by using the data for protocol conversion of a conversion data storing part 2f by a data processing part 2a. Also when a distribution condition which is preset beforehand in a data distributing part 2g by a distribution setting part 1c is established, a data communication processing part 1a simultaneously outputs messages for announcing the generation of an abnormality or the instruction of a work or the like in different configurations, such as a voice or text display based on plural announcement information (voice or text) preset beforehand in an application part 1f (the table of data base software or the like).
