4. WIRING

This chapter describes wiring cautions, wiring layout and wiring of terminals.

4.1 Wiring Cautions

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

• To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric equipment.

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

WARNING

− 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.

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

• For an instrument with 24 V power supply, supply power from a SELV circuit.

• A suitable power supply should be considered in the end-use equipment. The power supply must be

in compliance with a limited-energy circuits (maximum available current of 8 A).

• Use the solderless terminal appropriate to the screw size (M3).

Do not separate the module mainframe from the terminal base with the power turned on. If so, instrument failure may result.

WARNING

5.1 Node Address Setting

To identify each device connected to the network, it is necessary to set a different address to each device (node). For the DeviceNet, as it is possible to connect up to 64 devices including a master to the network, node address (MAC ID) from 0 to 63 can be set. For this setting, use a small blade screwdriver.

Set the address such that it is different to the other addresses on the same line. Otherwise, problems or malfunction may result.

5. SETTING

The number of communication words when conducting polling I/O communication can also be set via Explicit message communication, or by the configuration tool or rotary switch. However, when the number of communication words is set via Explicit message communication, or by the configuration tool or rotary switch, the value set by the DIP switch may be ignored.

5.4 Communication Environment Setting by Rotary Switch

Set communication environment of polling I/O communication of DeviceNet by using the “Node address setting switch” and the “DeviceNet communication speed setting switch” which are the rotary switch of the COM-JH.

The setting details cannot be check afterwards. When checking the details thus set, check them via Explicit message communication. In addition, as each switch position is moved during the setting, record the switch setting state before making the setting.

 Setting procedure

1. Turn off the power supply.

2. Before communication environment, record the switch positions of node address setting switch

and DeviceNet communication speed setting switch. (When this module is used for the first time, no recording is required.)

3. Set all the values of a node address setting switch

and a DeviceNet communication speed setting switch to “9.”

5. Select a setting item number with MSD of the node address setting switch, and set data with LSD

of the node address setting switch.

See  List of communication environment setting items (P. 24).

6. Set the DeviceNet communication speed setting switch in the order of “9,” “0” and “1.”

The RUN lamp turns on and then it turns off after registration of the set data is complete (after a lapse about 3 seconds).

7. Repeat the steps from 5. to 6. of above, and set other setting items.

However, set the DeviceNet communication speed setting switch in the order of “1,” “0” and “1” from the second setting.

8. First check that the RUN lamp goes off, and then turn off the power.

9. Return the switch positions of node address setting switch and DeviceNet communication speed

setting switch to the positions already recorded.

10. Turn on the power again.

The set data valid if the power is turned on again.

6. DeviceNet COMMUNICATION

6.2 Communication Method

COM-JH has supported “Polling I/O communication” and “Explicit message communication” as a communication method of DeviceNet.

6.2.1 Polling I/O communication

Polling I/O communication is the communication that master and slave always execute transmission and reception of data. Used always when checking data items such as measured values, etc. Set the following items before communication start.

• Communication data items (setting data items and measured data items)

• Number of communication controllers

• Number of communication words

• Controller address

• Action mode

• Automatic acquisition of controller address

Polling made once enables the following data items to be read or written via polling I/O communication.
