Provided is a management device or the like that can flexibly set a task cycle of a master device. The management device is a management device that manages a network including a master device and a slave device connected to the master device, and comprises: a transmission delay time prediction unit which predicts a transmission delay time on the basis of network configuration information and node information; a transmission delay time measurement unit which measures the transmission delay time in the network; and a transmission delay time setting unit which presents to the user, a predicted value predicted by the transmission delay time prediction unit and a measured value measured by the transmission delay time measurement unit, and sets a cycle setting transmission delay time for setting a task cycle in which the master device transmits a signal to the slave device, according to the selection operation of the user.

Management device, management method and recording medium

The present invention provides a management device that assists in setting a ring topology in a design network configuration. This management devicemanages a network that includes a master deviceand a plurality of slave devicesconnected to the master device, the management deviceincluding a ring topology assessment unitfor assessing, on the basis of design network configuration information Dcreated by a user and slave information Dthat represents the unique information per type of each slave device, whether a ring topology configured from a plurality of slave devicescan be generated.

Network management device, management method, and recording medium

Provided is a management device that makes it possible for a user of a device different from the management device to smoothly assist troubleshooting in the management device. A management deviceis a management device that manages a network including one or more nodes, and includes: a data acquisition portion that generates first data in binary format which indicates a state of the network, and a data conversion portionthat converts the first data into second data in viewer format.

Management device, assistance device, management method, and recording medium for converting data into viewable format

A control system includes a master device and one or a plurality of slave devices connected to the master device via a field network. In a storage unit of each slave device, a node address is arranged in a unique region for each model of the slave devices. The control system further includes an information providing part which provides, in any slave device, information for specifying the region in which the node address is stored in the storage unit to the master device.

Control system and control method

A control system synchronizes input timing and output timing between functional units, while achieving the contradictory aspect of shortening the communication cycle of data frames transferred on a network. An information processing apparatus calculates parameters for the functional units included in a slave device in accordance with a mode selected from a plurality of available modes. The modes include a first mode in which timing to obtain a status value from the control target and timing to update an output value for the control target are synchronized between all the functional units included in the slave device, and a second mode in which the timing to obtain a status value from the control target and the timing to update an output value for the control target are synchronized between specific functional units included in the slave device.
