摘要:
A data collection apparatus enables to connect to a support center via a network. The data collection apparatus has a measuring section which measures a physical quantity, a data storing section which stores measurement data obtained by the measuring section, in association with at least one of sound data and image data, a data communicating section which transmits and receives data to and from the support center, and an outputting section which reproduces and displays the transmitted and received data.
摘要:
A home agent receives a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network. This home agent requests the mobile terminal, based on a measured result of internal resources, to bypass the home agent to perform a communication with a source terminal.
摘要:
A programmable controller is disclosed that incorporates a sequence control program adapted to input and output information to a variety of local intelligent appliances at a high velocity and a high efficiency in the field of factory automation for efficiently controlling factory production lines or the field of process automation for controlling multiple industrial processes. Provided for this purpose is an improved a change-over system associated with a 1-bit processor and an ordinary processor for executing the sequence control program. Also improved are functions for a user to particularly specify a BASIC program, software/hardware control functions for a group of I/O boards for transferring signals to receiving signals from the local appliances, and the ability to program the internally stored sequence control program.
