fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above men­tioned applications.

3 Safety Precautions

!WARNING Never attempt to disassemble a Unit or touch the inside of Unit while power is
being supplied. Doing so may result in serious electrical shock or electrocu­tion.
!WARNING Provide safety measures in external circuits, i.e., not in the Programmable
Controller (CPU Unit including associated Units; referred to as “PLC”), in order to ensure safety in the system if an abnormality occurs due to malfunc­tion of the PLC or another external factor affecting the PLC operation. Not doing so may result in serious accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• 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 countermeasure for such errors, external safety measures must be provided to ensure safety in the system.
• The PLC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a counter-
xvi
Operating Environment Precautions 4
measure for such problems, external safety measures must be provided 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 being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in
PROGRAM mode). Confirm safety thoroughly in advance before changing the status of any part of memory allocated to I/O Units, Special I/O Units, or CPU Bus Units. Any changes to the data allocated to any Unit may result in unex­pected operation of the loads connected to the Unit. Any of the following oper­ation may result in changes to memory status.
• Transferring I/O memory data to the CPU Unit from a Programming Device.
• Changing present values in memory from a Programming Device.
• Force-setting/-resetting bits from a Programming Device.
• Transferring I/O memory files from a Memory Card or EM file memory to the CPU Unit.
• Transferring I/O memory from a host computer or from another PLC on a network.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory area. Doing either of these without confirming safety may result in injury.

•EMC Directives

6-2 Concepts

EMC Directives
OMRON devices that comply with EC Directives also 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 EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic
Interference standards in the EMC (Electromagnetic Compatibility) standards are as follows:

DeviceNet products that meet EC directives must be installed as follows:
1,2,3...
1,2,3...
1. DeviceNet Units are designed for installation inside control panels. All De­viceNet Units must be installed within control panels.
2. Used reinforced insulation or double insulation for the DC power supplies used for the communications power supply, internal circuit power supply, and the I/O power supplies.
3. DeviceNet products that meet EC directives also meet the common emis­sion standard (EN50081-2). When DeviceNet products are built into equip­ment, however, the measure necessary to ensure that the standard is met will vary with the overall configuration of the control panel, the other devic­es connected to the control panel, and other conditions. You must there­fore confirm that EC directives are met for the overall machine or device, particularly for the radiated emission requirement (10 m).
The following examples show means of reducing noise.
. 1. Noise from the communications cable can be reduced by installing a ferrite
core on the communications cable within 10 cm of the DeviceNet Unit.

Overview of DeviceNet Section 1-1

1-1 Overview of DeviceNet

DeviceNet is a multi-bit, multi-vendor network that combines controls and data on a machine/line-control level and that conforms to DeviceNet open field net­work specifications.
Three types of communications are supported: 1) Remote I/O master commu­nications that automatically transfer I/O between slaves and the CPU Unit to which a DeviceNet Unit is mounted without any special programming in the CPU Unit, 2) Remote I/O slave communications that automatically transfer I/O between the Master and the CPU Unit to which a DeviceNet Unit is mounted, and 3) Message communications that read/write messages, control operation, or perform other functions for other CPU Units to which a DeviceNet Unit is mounted and slaves. Message communications are achieved by executing specific instructions (SEND (192), RECV (193), and CMND (194)) from the program in the CPU Unit to which the DeviceNet Unit is mounted.

The following functions are supported with a CS/CJ-series DeviceNet Unit.
a) I/O area words can be flexibly allocated for remote I/O Master and
Slave communications. Three types of fixed allocations as well as
user-set allocations through allocated DM Area words are possible. b) More than one DeviceNet Unit can be mounted under a single PLC. c) More than one DeviceNet Unit can be connected in a single network.
With the Configurator, remote I/O can be allocated in any order, i.e.,
not necessarily in the other of node addresses. Note The Configurator that is connected through a dedicated Board or
Card uses one node in the DeviceNet network. It does not use a node if it is connected by a serial line.
2. A CS/CJ-series DeviceNet Unit can function as either a master or slave in remote I/O communications. Both can be used simultaneously.
3. With a CS/CJ-series DeviceNet Unit, the DeviceNet network can be treat­ed exactly like a Controller Link, Ethernet, or other network for message communications or remote programming and monitoring by a CX-Pro­grammer.
