CAUTION

 This is a Class A instrument. In a domestic environment, this instrument may cause radio

interference, in which case the user may be required to take adequate measures.

 This instrument is protected from electric shock by reinforced insulation. Provide

reinforced insulation between the wire for the input signal and the wires for instrument power supply, source of power and loads.

 Be sure to provide an appropriate surge control circuit respectively for the following:

- If input/output or signal lines within the building are longer than 30 meters.

- If input/output or signal lines leave the building, regardless the length.



This instrument is designed for installation in an enclosed instrumentation panel. All

high-voltage connections such as power supply terminals must be enclosed in the instrumentation panel to avoid electric shock by operating personnel.



All precautions described in this manual should be taken to avoid damage to the

instrument or equipment.

 All wiring must be in accordance with local codes and regulations.  All wiring must be completed before power is turned on to prevent electric shock,

instrument failure, or incorrect action. The power must be turned off before repairing work for input break and output failure including replacement of sensor, contactor or SSR, and all wiring must be completed before power is turned on again.



To prevent instrument damage or failure, protect the power line and the input/output lines

from high currents with a protection device such as fuse, circuit breaker, etc.

 Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid

electric shock, fire or malfunction.

 Tighten each terminal screw to the specified torque found in the manual to avoid electric

shock, fire or malfunction.

 For proper operation of this instrument, provide adequate ventilation for heat dispensation.  Do not connect wires to unused terminals as this will interfere with proper operation of the

instrument.

 Turn off the power supply before cleaning the instrument.  Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or

discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.

 To avoid damage to instrument display, do not rub with an abrasive material or push front

panel with a hard object.

 Do not connect modular connectors to telephone line.

NOTICE

 This manual assumes that the reader has a fundamental knowledge of the principles of electricity,

process control, computer technology and communications.

 The figures, diagrams and numeric values used in this manual are only for purpose of illustration.  RKC is not responsible for any damage or injury that is caused as a result of using this instrument,

This manual describes the specifications, mounting, wiring and setting of switch and data instructions for the COM-H.

1.1 Product Outline

The COM-H DeviceNet communication converter (hereafter called “COM-H”) is a communication converter used to connect the DeviceNet that is a multivendor compatible open field network to our RKC controllers (SR Mini HG SYSTEM, REX-F400/F700/F900, CB100/CB400/CB500/CB700/CB900, SA100/SA200, MA900/MA901, LE100, REX-PG410). On the DeviceNet, a programmable controller (hereafter called “PLC”) or personal computer becomes a master device, while the COM-H, a slave device.

MA900/MA901 can be connected together with the LE100. The maximum number of

controllers when connected together is 24 in total. However for the MA900/MA901, one

MA900 is counted as four controllers and one MA901, as eight controllers.

1.1.2 EDS file

As for the EDS file of COM-H, be attached to COM-H by a floppy disk. Use the EDS file when recognizing the COM-H on the DeviceNet by using a configurator (tool used to set a master or slave environment on the DeviceNet) of each manufacturer.

For details, see Configuration Tool Instruction Manual of each company or Instruction Manual of the master product.

4. WIRING

4.1 Wiring

To prevent electric shock or instrument failure, do not turn on the power until all the wiring is completed.

CAUTION

Power supply wiring

WARNING

• Use power supply as specified in power supply voltage range.

• Power supply wiring must be twisted and have a low voltage drop.

• Provide separate power supply for this instrument independent of other input/output circuits,

motors, equipment and operating circuits.

• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

− Shorten the distance between the twisted power supply wire pitches to achieve the most

effective noise reduction.

− Always install the noise filter on a grounded panel.

− Minimize the wiring distance between the noise filter output and the instrument power

supply terminals to achieve the most effective noise reduction.

− Do not connect fuses or switches to the noise filter output wiring as this will reduce the

effectiveness of the noise filter.

− Take into consideration the instrument power supply voltage and filter frequency

characteristics when selecting the most effective noise filter.

• To the instrument with power supply of 24 V, please be sure to supply the power from SELV circuit.

Ground wiring

4.2 Connections

To prevent electric shock or instrument failure, turn off the power before connecting or disconnecting the instrument and peripheral equipment.

CAUTION

 Connect connectors correctly in the right position. If it is forcibly pushed in with pins in

the wrong positions, the pins may be bent resulting in instrument failure.

WARNING

 When connecting or disconnecting the connectors, do not force it too far to right and left

or up and down, but move it on the straight. Otherwise, the connector pins may be bent, causing instrument failure.

 When disconnecting a connector, hold it by the connector itself. Disconnecting

connectors by yanking on their cables can cause breakdowns.

 To prevent malfunction, never touch the contact section of a connector with bare hands

or with hands soiled with oil or the like.

 To prevent malfunction, connect cable connectors securely, then firmly tighten the

connector fastening screws.

 To prevent damage to cables, do not bend cables over with excessive force.

 Cable

Use the communication cable (thick cable or thin cable) that matched specification of DeviceNet.

By thickness of a cable to use and connection method, usable connection connector type is different.

For cable specifications, connection method and vendor, see the home page of ODVA (Open DeviceNet Vender Association). URL: http://www.odva.org

Terminating

• Trunk/Drop lines

The trunk line refers to the cable that has Terminating Resistors on both ends. Cables branching from the trunk line are known as drop lines. Use the DeviceNet communication cable (thick or thin cable) for Trunk/Drop lines.

• Connection methods

Two methods can be used to connect DeviceNet nodes: The T-branch method and the multi-drop method. With the T-branch method, the node is connected to a drop line created with a T-branch Tap. With the multi-drop method, the node is directly connected to the trunk line or the drop line.

• Terminating resistors

In DeviceNet a terminating resistor must be connected to each end of the trunk line Specification of terminating resistor: 121 Ω, ±1 %, 1/4 W (Metal film resistance)

• Communications power supplies

To use DeviceNet, connect a communications power supply (24 V DC) to the communications connector of each node with a cable.

For network laying requirement of DeviceNet/method, see Instruction Manual of master product or DeviceNet specifications. DeviceNet specifications are available from ODVA (Open DeviceNet Vender Association). URL: http://www.odva.org

4.2.2 Connection to RKC controllers

Figures of the open-style connector type are used for the following description. However, those of the micro-style connector type can be similarly used.

(1) Connection to SR Mini HG

Communication interface can select either of RS-422A or RS-232C. (Specify when ordering) It is necessary for communication interface of SR Mini HG to correspond with COM-H. One SR Mini HG control unit can connect for one COM-H.
