3 Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing
so may result in electric shock.
!WARNING Do not touch any of the te r minals o r ter minal blocks while the power is bein g
supplied. Doing so may result in electric shock.
!WARNING Provide safety measures in external circuits (i.e., not in the Programmable
Controller), includin g the following items, to ensure safety in the system if an abnormality occurs due to malfunc tion of the PLC or anoth er external factor affecting the PLC operation. Not doing so may result in serious accidents.
• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnorm al signals caused by broken signal lines, momentary power interruptions, or other causes.
• Emergency sto p cir cuits, inter lock circui ts, limit circu its, and sim ilar safety measures must be provided in external control circuits.
xx
Operating Environment Precautions 4
• The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a counterme asure for such errors, external safety measures must be provided to ensure safety in the system.
• The PLC outputs m ay remain ON or OFF due to depos ition or bur ning of the output relays or destr uction of the output transistors. As a cou nter­measure for such problems, extern al safety measures must be provide d to ensure safety in the system.
• When the 24-VDC output (service power supply to the PLC) is overloaded or short- circuited, the voltage may drop and result in the outputs b eing turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Other wise, the input signals may not be readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or changing c ontents of the I/O memory ar ea. Doing either of these without confirming safety may result in injury.

1-1 Overview

1-1-1 What Is the Controller Link?

The Controller Link is a n FA network that can se nd and receive large data packets flexibly and easily among the OMRON C 200HX/H G/HE Programma­ble Controllers (PLCs), CS-series PLCs, CJ-ser ies PLCs, CVM1 PLCs, CV­series PLCs, CQM1H-series PLCs, and IBM PC/AT or compatible computers.
The Controller Link suppo rts data links that enable data shar ing and a mes­sage service that enables sending and receiving data when required. Data link areas can be freely set to create a flexible data link system and effectively use data areas.
High-volume data transmissions are possible at high speed and so a wide range of networks, from low-level systems to high, can be easily created.
There are two types of networks: networ ks connected with shielded twist ed­pair cable and networks con nected with optical fiber c able. Using a Repeater Unit in networks co nnected with t wisted-pair cable makes it possible to use a variety of different wiring configurations, such as T-branch wiring, long-dis­tance wiring, and partial conversion to optical fiber. (Refer to the CS1W-
CLK12, CVM1-CLK12 Optical Ring Controller Link Units Operation Manual
(W370) for detail on optical fiber connections.) The functions of a Controller Link Network are illustrated below.

Data Links
Data links allow the constant sharing of data in predetermined data areas between nodes, between PLCs, or between a PLC and an IBM PC/AT or com­patible computer on the network. Dat a lin ks do not requ ir e the use of commu­nications programs on the PLC (CPU Unit) or IBM PC/AT or compatible computer. Data written in the send area of the local node will be automatically sent to the receive area of other nodes.
The I/O area (CIO area), link area (LR area), DM Area area (DM area), an d extended DM Area area (EM area) c an be freely set in the send or rece ive area. (The area used for sending or receiving data using the data link function is called “data link area.”)
The data link area can be set automatically or manually.

Automatic Setting Used for simple data link processing. Data link can be performed by simply
setting parameters in the DM area of the PLC. Send data size per n ode is the sa me for all nodes. All no des par ticipating i n
the data link share the same data.
Manual Setting Used for flexible data link processing depending on each system.
Using the Controll er L ink Su pport Software, indivi dual data link tables can be set for each node and the data link area can be freely allocated for each node. Send data size per node can be fre ely set. It is als o possible to set nod es for only send or rece ive data. With the Controller Link Unit, the data link can be set to receive only a part of the data link area of other nodes.
Message Service
This function controls data transmission with particular nodes, reading or writ­ing of status data, c hangi ng of op eration mod es, etc., by executing communi­cations instruc tions on a program. The communications instr uctions include SEND/RECV instructions for data transmission and CMND instructions for issuing various commands.

Overview Section 1-1
k
SEND/RECV The SEND or RECV instruction sends or receives data in an area of a particu-
lar node. The SEND instruction sends data from an area of the local node and writes to
an area in the designated node. The RECV instructio n requests the designated node to send ar ea data and
writes the data to the local node.
CMND The CMND instruction issues a command to read or write data of other nodes,
control, or read erro r logs. With t he Control ler LInk Unit, O MRON’s command protocol called “FINS commands” is used.
Note Since the C200HX/HG/HE PLCs do not s upport the CMND instr ucti ons, arbi-
trary commands cannot be issued.
RAS
RAS performs real-time monitoring of the network status. If an er ro r oc cu rs i n the network, RAS records and displays the time and contents of the error.
Status Area Data Link Status Area
When the data link function is used, the data link status is reflected in the data link status area of the PLC.
Network Status Area Other than the Data Link: The network sta tus such as the sta te of node par ticipati on is reflect ed in the status area of the PLC.
