1-3 CompoBus/D System Configuration
CompoBus/D is a
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.
SI/O area words can be flexibly allocated for remote I/O communications.
SMore than one Master Unit can be mounted to a single PC.
SMore than one Master Unit can be connected in a single Network.

C200HX/HG/HE PCs: | 64 nodes max. (including the Master Unit) |
C200HS PCs: | 33 nodes max. (including the Master Unit) |
Note 1. The Master Unit occupies one node of the CompoBus/D Network.
Note 2. If C200HS PCs are used, only remote I/O communications are possible.
Note 3. If one node uses more than one word, the maximum number of nodes will be reduced by one node for each extra word that is used.
