6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives conform to the related EMC
standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan­dards in the system used by the customer, however, must be checked by the
customer.

EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN50082-2
EMI (Electromagnetic Interference): EN61000-6-2

6-3 Conformance to EC Directives

The CS1W-SLK11 and CS1W-SLK21 SYSMAC LINK Units comply with EC
Directives. To ensure that the machine or device in which these SYSMAC
LINK Units are used complies with EC directives, the SYSMAC LINK Units
must be installed as follows:

1,2,3...

1. In order to conform with EC Directives, the SYSMAC LINK Units must be
installed within a control panel. Use an SA20-712 (made by NITTO ELEC­TRIC WORKS) or a similar model.

2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.

3. SYSMAC LINK Units complying with EC Directives also conform to the
Common Emission Standard (EN50081-2). When a SYSMAC LINK Unit is
built into a machine, however, noise can be generated by switching devic­es using relay outputs and cause the overall machine to fail to meet the
Standards, particularly with radiated emission for 10-m regulations. The
customer must, therefore, take measures to ensure and perform final
checks to confirm that devices and the overall machine conform to EMC
standards.

Overview Section 1-1

1-1 Overview

The SYSMAC LINK is an FA network that can send and receive large data
packets flexibly and easily among the OMRON CS-series, C200HX/HG/HE,
CVM1, CV-series, C1000H, C1000HF, C2000H, and CQM1H-series Program­mable Controllers (PLCs), as well as IBM PC/AT or compatible computers.

The SYSMAC LINK supports data links that enable data sharing and a mes­sage service that enables sending and receiving data when required. Data
link words can be freely set to create a flexible data link system and effectively
use memory areas.

The network is connected using coaxial cable or optical fiber cable.

Coaxial System (Coaxial Cable)

Optical System (Optical Fiber Cable)

Internetwork Connections Communications across bridges or gateways can include up to three net-

works, including the local network. A CS-series, CVM1, or CV-series PLC can
be used as the bridge or gateway to easily and economically create networks
controlling multiple lines.

SYSMAC LINK Unit Features Section 1-2

1-2 SYSMAC LINK Unit Features

CS-series SYSMAC LINK Units are equipped with a variety of special features
including some developed from those incorporated by the C-series SYSMAC
LINK Unit. These features allow PLCs in a SYSMAC LINK Network to commu­nicate with or automatically exchange data with other PLCs in the same Net­work and to communicate with interconnected Networks.

High Speed, Reliability,
and Flexibility

The specialized communications LSIs used in all SYSMAC LINK Units deliver
high speed, reliability, and flexibility in an advanced data link system, while
optical fiber cable systems provide high-speed communications with unparal­leled immunity to noise.

In the event of an error or failure in the polling node, another node automati­cally takes over management of the SYSMAC LINK System without stopping
the entire network. The CX-Net within the CX-Programmer can monitor and/or
program PLCs anywhere in the network via the SYSMAC LINK System.

Distributed Control with
Data Links

The data link function transfers data to and from other nodes automatically,
establishing simple but powerful peer-to-peer links between nodes. Data links
can be generated automatically or the user can use the flexibility of manually
generating data links to eliminate unused link words, improve data link I/O
response time, and to even create several data link groups in one network.

The data link communications cycle time can be fixed at a constant value, so
even simultaneous remote programming/monitoring and NETWORK READ/
WRITE instructions (RECV(98)/SEND(90)) execution have no effect on the
data link I/O response time.

The data link function allows data exchange not only between PLCs but also
between PLCs and host computers in the network, making it possible to
develop communications software with ease.

Active Communications Communications can also be programmed using ladder-diagram instructions

(SEND(90), RECV(98), and CMND(490)) to facilitate communications with
other PLCs and host computers on an as-needed basis. Use of these instruc­tions enables the following:

1,2,3... 1. Broadcast transmissions

2. Response monitoring time setting (response time-out setting)

3. Transmit retry setting

4. Enabling/disabling responses

Internetwork
Communications

Routing tables can be set up in network PLCs so that communications are
possible with interconnecting networks or networks one network away from
the local network. This includes both bridging to other SYSMAC LINK Net­works or passing gateways to other OMRON networks, including those in
SYSMAC NET Link Systems or SYSMAC BUS/2 Remote I/O Systems.

Remote Access The CX-Net within the CX-Programmer can access PLCs on the local net-

work, on adjacent networks, or on networks one removed from the local net­work, including Controller Link and Ethernet Networks. Access can be used to
monitor operation and/or manipulate data and programs.

RAS Functions SYSMAC LINK Units are equipped with three RAS functions (RAS is an acro-

nym for reliability, availability, and serviceability). The Polling Node Backup
and Failed Node Bypass (optical systems only) functions prevent the network
from failing when one Unit fails. The Internode Echo Test function aids in com­munications troubleshooting.

Remote monitoring of the network’s operating status and error logs also aids
in troubleshooting and quick correction of communications problems.

work can be tested. The test settings are made using the Support Software.

Broadcast Test All the nodes within a specified network can be tested using the Support Soft-

ware broadcast test function.

Error Log
(See page 137)

If an error occurs in the Unit, the time of the error and the error contents are
logged in EEPROM within the Unit. The logged error information can be read
using the Support Software.

Polling Node Backup
(See page 143)

If an error occurs in the polling node, the Unit at another node automatically
becomes the polling node and rebuilds the network.

Node Bypass
(See page 143)

If a backup power supply is used with an Optical SYSMAC LINK System, any
node that goes down will be automatically bypassed, preventing the entire
network from going down.
