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 othe
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
Low Voltage Directive
Safety standard: EN50178: 1997
(Radiated emission: 10-m regulations)
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 powe
supplies used for the communications power supply and I/O powe
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.

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: Pe-
ripheral 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.

ntroduction
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 follow-
ing 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

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 program” that is executed cyclically and the “interrupt programs” that are executed 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 parameter 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.

Caution The PLC continues to refresh I/O bits even if the PLC is in PROGRAM mode,
MONITOR Mode The program is executed in MONITOR mode and the following operations
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.

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.

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
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 communica-
tions 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)

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 (
clically).
