Cat. No. Q103-E1-7
Maximum Communications Cycle Time of
Only 1 ms
(High-speed Communications Mode)
Exchanges 256 I/O points of data with a maximum
of 32 Slaves at a maximum communications cycle
time of only 1 ms per point.
Long-distance Communications Mode
With a trunk line length of 500 m and a total branch
line length of 100 m (2-conductor VCTF cable), you
can branch in any way required using a special flat
cable or a 4-conductor VCTF cable as long as the
total wiring length is 200 m or less. Communicate
at a cycle time of only 6 ms.
*The Long-distance Communications Mode is not supported by the SRT1 Series.
Complicated
wiring between
the PC and
repeater terminal
block.
System
expansion
is time-
consuming.
Connects through a single dedicated cable,
thus greatly saving wiring effort.
Cabtire or flat cable is selectable.
●
Cabtire cable is available for multi-drop, T-
branch, or multi-branch lines.
●
Flat cable connects to T-branch connectors, thus
ensuring ease of system expansion.
Note:
Cabtire and flat cables cannot be used together.
An Analog Input Terminal with four points
and an Analog Output Terminal with two
points are available.

of ON/OFF
signals is time-

A cycle
time of 1 ms
max. for up to
32 Slaves, 256
I/O points.

connects
sensors and
Slave Units.

System Design
With conventional High-speed Communications Mode, the following restrictions on the number of branching
points and cable length had to be considered when designing the system.
With a Special Flat Cable or a 4-conductor VCTF cable:
Main line length A: 30 m max. Branch line lengths B, C, and D: 3 m max. Total branch line length B + C + D: 30 m max.
SYSMAC CS1
Branch line length: 3 m max.

Expansion
Using CompoBus/S Long-distance Communications Mode (with a Special Flat Cable or a 4-
conductor VCTF cable) removes restrictions on main and branch line lengths. Branch freely up to a
total cable length of 200 m.

Repeater terminal blocks must be

Terminating resistance
* Baud rate: 93.75 kbps
* Connect a terminating resistance at the end of the cable furthest from the Master.
* With 2-conductor VCTF cable (in Long-distance Communications Mode), main line length: 500 m max.
2-conductor VCTF
cable allows multi-
branching, thus
easily allowing an
increase in the
number of Slaves.

Programmable Slaves combine devices, such as sensors and
actuators, into one functional unit that is treated as a DeviceNet slave.
Programmable Slaves greatly facilitate device distribution and
functional organization. They help standardize programming between
units and reduce the amount of programming required at the master.
I/O and operational checks can be performed for each functional unit,
rather than waiting for final system assembly, as with conventional
distributed I/O systems.
●
Functions
OMRON Programmable Slaves function as DeviceNet slaves, yet they
provide PLC functionality to enable easy system expansion and create
new potential.

NT Links
Host Links
Multiword I/O links and explicit messages are
used to control slaves from the master. Log
data for communications can be sent in one
operation whenever necessary using explicit
messages.
Expansion Units
(3 max.)
Just one Unit is required for each distributed block,
reducing the number of interfaces for multipoint
communications to, in turn, reduce costs.
