PRODUCT 1.4 Slave unit parts 10.7 Part name Description Indicates the status of the slave unit and network with RUN, ERR, L/A IN, Monitoring lamp L/A OUT, INFO, PW, and PW(V). Rotary switch: Sets the slave unit node address. Setting switches Slide switch: Sets the action taken in the event of a communication error.
PRODUCT 1.5 Switches and LED indicators CAUTION ● Discharge static electricity from your body before touching the product. Static electricity may cause damage to the product. 1) Switches The switches are used to set the slave unit node address and the action taken on the output in the event of a communication error.
CAUTION 2. CAUTION ● Be careful of the surroundings and ensure safety before turning on or off the power. The system or solenoid valve (cylinder) may start operating suddenly. ● For the delay time, refer to the instruction manual for the master unit. Transmission delay in the system varies depending on the PLC scan time and other devices connected to the same network.
OPERATION 3. OPERATION 3.1 Setting the Switches CAUTION ● Discharge static electricity from your body before touching the product. Static electricity may cause damage to the product. ● Set switches while unit power is turned off. Since switch settings are read when the power is turned on, changes made to the settings after turning on the power are not recognized.
OPERATION 2) Setting other switches Set the action taken on the output when there is a communication error. Switches Settings Set the action taken on the output when there is a communication error CLR HLD (such as disconnection error and time over). (output mode setting)...
OPERATION 3.3 Correspondence between Slave Unit Output Number and PLC Address Number 1) PLC address correspondence table This correspondence table uses Omron’s PLC as an example. The serial transmission slave unit address is set to "node address 1". N4E0-T7EC1, N4E0-T7ECT1 (16-point output) Output Bit 00 to 15 Assigned address in the PLC memory...

OPERATION 2) Example of valve number array corresponding to T7EC solenoid output number In the table below, each valve number (Valve no.) consists of a number (the station number) and an alphabet (a for a-side solenoid and b for b-side solenoid). For example, “1a” refers to 1st station a-side solenoid.

OPERATION N4E0-T7EC2, N4E0-T7ECT2 (32-point output) The figure below is an example of mounting 16 stations of double-solenoid type solenoid valves. For single-solenoid types, there is no solenoid on the b-side. Manifold station no. No.2 No.4 No.6 No.8 No.10 No.12 No.14 No.16 No.1...
OPERATION 3.4 Programming The master unit handles this unit as a slave device (T7EC1, T7ECT1 for 16-point output, T7EC2, T7ECT2 for 32-point output). There are two types of data: The PDO (Process Data Objects) output data sent from the master unit to a slave device (in case of this product;...
INSTALLATION 4. INSTALLATION The communication cable and power cable must be connected for the N4E0-T7EC to function. If these cables are incorrectly connected, the product might not function, or this product and the devices used simultaneously could be seriously damaged in some cases. Always read this manual and User’s Manuals enclosed with the PLC and other connected units, and confirm that the cables are correctly connected.
INSTALLATION 4.1 Connecting and wiring to the network connector socket Although the EtherCAT network uses a standard Ethernet cable and has flexible wiring methods, there are limits depending on the wiring material and equipment (master, hub, and other devices) used. Always understand their specifications thoroughly before wiring.
INSTALLATION 4.2 Connecting and wiring to the unit/valve power socket The power plug is supplied with the product. The unit/valve power cables are wired to the supplied power plug and that plug is connected to the power socket on the slave unit. <Unit power>...

INSTALLATION CAUTION ● Always check the polarity and rated voltage thoroughly before connecting cables. ● Calculate the current consumption to select the power cable. ● Consider the voltage drop due to cables when selecting and wiring the cables if power is supplied to more than one slave unit (remote I/O unit) from one power supply.
MAINTENANCE 5. MAINTENANCE 5.1 Removing the product (slave unit) (1) After confirming safety, stop network communication as necessary and turn off all peripheral equipment. (2) After confirming safety, turn off the unit power and valve power as necessary. Note that if there are other slave stations on the OUT side of this product, communication on the OUT side will stop.
Page 24
MAINTENANCE CAUTION ● Be careful of the surroundings and ensure safety before turning on or off the power. The system or solenoid valve (cylinder) may start operating suddenly. ● Check the slave unit node address and the setting made to specify which action to take on the output in the event of communication error before turning on the unit power.
MAINTENANCE 5.3 Troubleshooting Troubleshooting for this slave unit must be performed not only for the single unit but for the entire system. The system may start operating suddenly depending on the communication state. Use extreme care and ensure safety during maintenance. [Fault 1] PW, PW(V) does not light up.
MAINTENANCE 5.4 Maintenance of components This section describes the cleaning and inspection of the slave unit for daily maintenance and what to do when replacing the slave unit. 1) Cleaning In order to use the product under optimum conditions, clean and inspect the product periodically. (1) For daily cleaning, wipe the product with a soft dry cloth.
