Abstract: Disclosed is an image forming apparatus configured to form an image based on a first print job transmitted from a first type information processing device, and form an image based on a second print job transmitted from a second type information processing device different from the first type information processing device, the image forming apparatus includes a memory configured to store a plurality of print jobs including the first print job and the second print job and a controller configured to control the image forming apparatus to execute image formation based on the plurality of print jobs in an order stored in the memory, with the controller being configured to control whether to execute the image formation based on the selected print job.

Abstract: A system design supporting device includes a file specification receiving unit, a file acquiring unit, and a parameter setting unit. The file specification receiving unit receives specification of a unique device information definition file from a plurality of unique device information definition files stored in the server. The file acquiring unit acquires, from the server, the unique device information definition file whose specification is received by the file specification receiving unit. The parameter setting unit sets a parameter for controlling operation of a unit, on the basis of the unique device information definition file.

Abstract: To collectively set multi-CPU parameters included in a project of each CPU having a multi-CPU relationship, a parameter setting device includes: unit configuration information used for managing, for each PLC, unit information in which a CPU and a project allocated to the CPU are associated with each other; a unit-configuration analyzing unit that extracts a list of unit information on CPUs provided in a same PLC that includes a CPU specified by a user from the unit configuration information; and a parameter writing unit that acquires each project of CPUs provided in a same PLC that includes the CPU based on the extracted list of unit information when a parameter of a project of the specified CPU is set, and sets a setting content, which is same as a setting content regarding a project of the specified CPU, to each of the acquired projects.
