MELSEC iQ-R Series
GP-IB Interface Module
GP-IB (General Purpose Interface Bus) is a communication standard complying with IEEE 488.1 and used for variety of devices from computers to measuring equipment.
The module can be implemented into devices having an GP-IB interface utilizing its features and functions.
Connection to GP-IB devices
Up to 14 GP-IB-supporting devices can be connected when using the module as a controller. Features such as data exchange, reading the operating status, initialization of device dedicated functions, and startup from the programmable controller are supported. In addition, when used as a device, data send and receive requests from the GP-IB controller are supported, together with control by interface messages.
