Expanded System Configuration Section 1-3
Note 1. The standard protocols are provided as standard features with the CX-Pro-
tocol and Serial Communications Boards.
2. Protocol macros not supported by the CPU Unit’s built-in ports.
Note CompoWay/F (Host Function)
A CQM1H CPU Unit can operate as a host to send CompoWay/F commands
to OMRON components connected in the system. CompoWay/F commands
are executed by using the CompoWay/F send/receive sequences in one of the
standard protocols provided in the protocol macros.
1-3-2 Communications Networks
With the CQM1H CPU Unit, networks can be created using the following
Communications Units:
• CompoBus/S Master Unit
• Controller Link Unit (CQM1H-CPU51/61 only)
CompoBus/S Network CompoBus/S is a high-speed ON/OFF bus for remote I/O communications.
Connecting a CQM1-SRM21-V1 CompoBus/S Master Unit (a Dedicated I/O
Unit) to the network allows remote I/O communications, without programming
in the CPU Unit, between the PC and Slaves. High-speed communications
are performed with 256 points in a cycle time of 1 ms max. With the CQM1H-
SRM21-V1, a long-distance communications mode is also available in addi-
tion to the previous high-speed communications mode, enabling communica-
tions on a trunk line of up to 500 m.
Controller Link Network The Controller Link Network is the basic network of the OMRON PC FA Net-
works. When using a CQM1H-CPU51/61 CPU Unit, the CQM1H can be con-
nected to the network using a Controller Link Unit. This enables the flexible
and simple transfer of large amounts of data with other OMRON PCs (e.g.,
CQM1H, CS-series, C200HX/HG/HE, CVM1, and CV-series PCs) or with per-
sonal computers. Data links can be created between PCs so that data can be
shared without programming and FINS message communications can be per-
