Omron CompoBus/D (DeviceNet) Communications Card 3G3FV-PDRT1-SIN Benutzerhandbuch

CompoBus/D is a multi-bit, multi-vendor network that combines controls and data on a machine/line-
control level and that conforms to DeviceNet open field network specifications.

Two types of communications are supported: 1) Remote I/O communications that automatically trans-
fer I/O between Slaves and the CPU Unit of a SYSMAC PC without any special programming in the CPU
Unit and 2) Message communications are performed between a CPU Unit to which a Master Unit is
mounted and Slaves by executing specific instructions (such as CMND and IOWR, depending on the
model of SYSMAC PC used) from the program in the CPU Unit.

A Configurator (sold separately) can be used to enable following. This allows the support of an even
larger control system.
