Abstract

PURPOSE:To connect a programmable controller to a universal bus, by providing a means which takes out transmission data from a shared memory by applying HALT on the programmable controller, and a means which supplies a transmission request to a communication controller for universal bus based on the transmission data. CONSTITUTION:When data is received by the communication controller 3 via the universal bus 4, the data is taken out by an intermediate device 1. When HALT ready is issued from the programmable controller 2 in such state, a HALT signal is sent from the intermediate deice 1 to the programmable controller 2. In such a way, the intermediate device 1 takes out the transmission data from the shared memory 21, and also, writes reception data on the shared memory 21. And the intermediate device 1 supplies a data transmission request to the communication controller 3 following a HALT canceling processing based on the transmission data.
