PRECAUTIONS

8 EC Directives

8-1 Applicable Directives

•EMC Directives

•Low Voltage Directive

8-2 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 the overall machine. 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 on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

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

EMS (Electromagnetic Susceptibility): EN61800-3

EMI (Electromagnetic Interference):

EN50081-2/EN55011

(Radiated emission: 10-m regulations)

Low Voltage Directive

Safety standard: EN50178: 1997

8-3 Conformance to EC Directives

The 3G3MV series products comply with EC Directives. To ensure that the machine or device in which the PLC is used complies with EC Directives, the PLC must be installed as follows:

1, 2, 3... 1. The PLC must be installed within a control panel.

2.You must use reinforced insulation or double insulation for the DC power supplies used for the communications power supply and I/O power supplies.

3.OMRON PLCs complying with EC Directives also conform to the Common Emission Standard (EN50081-2). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.

SECTION 1

1-1 3G3MV-P10CDT Features and Functions

1-1-1 3G3MV-P10CDT Features

The 3G3MV-P10CDT PLC Option Units are compact CPM2C PLCs that have been equipped with a 3G3MV-Inverter interface. The 3G3MV-P10CDT incorporates a variety of special features just like the CPM2C, including synchronized pulse control, interrupt inputs, pulse outputs, and a clock function.

•The Inverter interface reduces wiring, and saves space. Instead of using a CPM2C with CIF11 to communicate to an 3G3MV-Inverter, the P10CDT communicates directly to the Inverter without the overhead.

•The 3G3MV-P10CDT itself can handle a wide range of machine control applications. In addition, the 3G3MV-P10CDT is capable of communications with devices such as personal computers and OMRON Programmable Terminals so it is ideal to use to expand or upgrade existing systems.

•The 3G3MV-P10CDT CPU Unit has a total of 10 I/O points: 6 inputs, 3 transistor outputs and 1 relay output.

•The communications port can be used simultaneously as two ports: Peripheral and RS-232C. The peripheral port supports Programming Devices, Host Link, and no-protocol communications. The RS-232C port supports Host Link, no-protocol (serial), 1:1 PLC Link, and 1:1 NT Link communications.

•Included is also an RS-422/485 interface (not all models) which allows for a cheap connection to other 3G3MV-P10CDT’s, other Inverters, NTterminals, etc.

Example System Configuration

A basic standalone application with HMI:

Introduction	SECTION 1
	A typical winder application:

The 3G3MV and PLC Option Unit take care of diameter calculation, dancer PID, user input, etc. The other simply run in speed control. This type of application uses both RS-232C and RS-422 communication.

Loss of Inverter functionality

Whenever the 3G3MV-P10CDT is attached to a 3G3MV Inverter, the following functionality of the Inverter is lost:

• Modbus communication through the RS-422 interface of the Inverter is disabled. The Modbus communication through the RJ-45 connector is still available.

Inverter-interface restriction

The following resources have limited control:

•Only one analog input can be read directly. The other input can be read by using the Transfer command in combination with PID with feedback.

•The analog outputs cannot be controlled by the 3G3MV-P10CDT

Note Minimum Inverter firmware version requirement: 24

I/O Memory	The program reads and writes data in this memory area during execution.
	Part of the I/O memory contains the bits that reflect the status of the PLC’s
	inputs and outputs. Parts of the I/O memory are cleared when the power is
	turned ON and other parts are retained.
Program	This is the program written by the user. The 3G3MV-P10CDT executes the
	program cyclically. (Refer to section 1-3-4 Cyclic Operation and Interrupts for
	details.) The program can be divided broadly into two parts: the “main pro-
	gram” that is executed cyclically and the “interrupt programs” that are exe-
	cuted only when the corresponding interrupt is generated.
PLC Setup	The PLC Setup contains various startup and operating parameters. The PLC
	Setup parameters can be changed from a Programming Device only; they
	cannot be changed from the program.
	Some parameters are accessed only when PLC’s power supply is turned ON
	and others are accessed regularly while the power is ON. It will be necessary
	to turn the power OFF and then ON again to enable a new setting if the pa-
	rameter is accessed only when the power is turned ON.
	Note Refer to 4-1 PLC-setup for details on the PLC Setup.
Communications	The Communications Switches determine whether the peripheral port and
Switches	RS-232C port connected through the communications port operate with the
	standard communications settings or the communications settings in the PLC
	Setup.
Inverter Interface	The PLC core communicates to the Inverter through IR-, DM-memory, either
	by direct mapping or through the Transfer command.
	Note Refer to section 5-4 Transfer command for more details.

Introduction

SECTION 1

1-3-2 Operating Modes

3G3MV-P10CDT Units have 3 operating modes: PROGRAM, MONITOR, and RUN.

PROGRAM Mode The program cannot be executed in PROGRAM mode. This mode is used to perform the following operations in preparation for program execution.

•Changing initial/operating parameters such as those in the PLC Setup

•Writing, transferring, or checking the program

•Checking wiring by force-setting and force-resetting I/O bits

Caution The PLC continues to refresh I/O bits even if the PLC is in PROGRAM mode, so devices connected to output points may operate unexpectedly if the corresponding output bit is turned ON by transferring I/O memory or forcesetting output bits from a Programming Device.

MONITOR Mode	The program is executed in MONITOR mode and the following operations
	can be performed from a Programming Device. In general, MONITOR mode
	is used to debug the program, test operation, and make adjustments.
	• Online editing
	• Monitoring I/O memory during operation
	• Force-setting/force-resetting I/O bits, changing set values, and changing
	present values during operation
RUN Mode	The program is executed at normal speed in RUN mode. Operations such as

1-3-3 Operating Mode at Startup

The operating mode of the 3G3MV-P10CDT when the power is turned ON depends upon the setting of pin 2 on the DIP switch on the front of the 3G3MV-P10CDT, the PLC Setup settings in DM 6600, and the Programming Console’s mode switch setting if a Programming Console is connected.

PLC Setup setting			Operating mode
Word	Bits	Setting
DM 6600	08 to 15	00 (Hex)	See note 1.
		01 (Hex)	Startup mode is the same as the operating
			mode before power was interrupted.
		02 (Hex)	Startup mode is determined by bits 00 to 07.
	00 to 07	00 (Hex)	PROGRAM mode
		01 (Hex)	MONITOR mode
		02 (Hex)	RUN mode

Note 1. The operating mode at startup depends upon the setting of DIP switch pin 2 and the Programming Device connected to the communications port (peripheral port).

Programming Device	Pin 2 OFF	Pin 2 ON
None	PROGRAM mode	RUN mode
Programming Console	Operating mode set on the Programming Console’s
	mode switch
Other device	PROGRAM mode

The default setting for bits 08 to 15 of DM 6600 is 00. If this default setting is used and pin 2 is OFF, the 3G3MV-P10CDT will automatically start operating in RUN mode when the power is turned ON.

Note 2. If pin 2 is OFF and only an RS-232C cable is connected to the communications port (i.e., there is no peripheral port connection), the 3G3MV-P10CDT will automatically start operating in RUN mode when the power is turned ON. Example Cable Connections:

CS1W-CN118 and XW2Z-200S/500S CS1W-CN118 and XW2Z-200S-V/500S-V

CPM2C-CN111 and XW2Z-200S/500S (no peripheral port connection) CPM2C-CN111 and XW2Z-200S-V/500S-V (no peripheral port connection)

1-3-4 Cyclic Operation and Interrupts

Basic CPU Operation	Initialisation processing is performed when the power is turned on. If there
	are no initialisation errors, the overseeing processes, program execution, I/O
	refreshing, and communications port servicing are performed repeatedly (cy-
	clically).
