12 1-1 NU-DN1 Overview 1 Overview Before Using The NU-DN1 operates as a slave unit of DeviceNet communication. Using DeviceNet communications, the sensor amplifiers and other units connected to the NU-DN1 can transmit their ON/OFF control signals and current values as communication data to PLC or other equipment. The NU-DN1 supports DeviceNet I/O communication (polling) and explicit messaging. I/O polling enables data communication without the need of a ladder program. Explicit messaging allows for reading/writing sensor amplifier parameters and issuing operation commands to the sensor amplifiers. System configuration example KV-DN20 MS NS ON TERM. PLC or other host device (DeviceNet master unit) NU-DN1 Device Net slave unit N-bus compatible sensor amplifier The NU-DN1 can connect sensor amplifiers (expansion units) which support N-bus. ("N-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.) Different types of sensor amplifiers with N-bus support can be connected up to 16 units to the single NU-DN1 unit. (The number of connectable units depends on sensor amplifiers.) "Types and Number of Connectable Sensor Amplifiers" (page 2-2) 1-2

17 Connection and Configuration This chapter explains the procedures for connecting sensor amplifiers to the NU-DN1 and the communication settings Installation and Connection to Sensor Amplifiers Wiring Communication Settings

18 2-1 Installation and Connection to Sensor Amplifiers This section provides the procedures for installing the NU-DN1 on the DIN rail and connecting to sensor amplifiers. 2 Connection and Configuration Types and Number of Connectable Sensor Amplifiers The NU-DN1 can be connected with the sensor amplifiers (expansion units) which support N-bus. ("N-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.) Different types of sensor amplifiers with N-bus support can be connected to the NU-DN1. The NU-DN1 assigns an ID number between 1 and 16 to the connected sensor amplifier. Some models of sensor amplifiers occupy multiple ID numbers. Multiple sensor amplifiers can be connected as long as the number of occupied IDs does not exceed 16. The sensor amplifiers which can be connected to the NU-DN1, and the number of occupied ID numbers are shown below. Part name Model Number of occupied ID numbers Digital fiber sensor FS-N10 / N12* 1 Digital fiber sensor (2-output) FS-N14* 2 Digital laser sensor (0-line / connector type) LV-N10/N12C* 1 Digital laser sensor (cable type) LV-N12* 2 Digital photoelectric sensor PS-N10/N12* 1 e-con input unit NU-EN8N 8 2-2

19 2-1 Installation and Connection to Sensor Amplifiers ID Number Assignments to Sensor Amplifiers ID numbers are assigned sequentially, starting from the adjacent sensor amplifier or unit connected to the NU-DN1. NU-DN1 FS-N10 FS-N12* FS-N14* NU-EN8N 2 ID No Connection and Configuration 12 Point Since ID numbers are assigned automatically, changing the number of sensor amplifiers or their connection sequence may require modification of the control program. In addition, sensor amplifiers cannot be connected next to the the NU-EN8N (NU-EN8N must be the last connection). These considerations should be taken when configuring the sensor amplifiers and control programs. You can also assign the ID numbers manually. "(4) Manually Assigning the Sensor ID Number (Manual ID Assignment Function)" (page -27) An error will occur if the number of occupied ID stations exceeds 16. "Error Information" (page 5-6) Reference When the NU-EN8N is connected, an error will not occur even if the NU- EN8N ID number exceeds 16, and outputs up to the ID number 16 can be used. Example) When ten FS-N10 units and one NU-EN8N unit are connected to the NU-DN1, the NU-EN8N outputs 1 to 6 can be used. 2-

25 2- Communication Settings Use the following procedure to connect the NU-DN1 to the DeviceNet system. Point This manual covers only the functions and settings of a DeviceNet master unit which are required for communication with the NU-DN1. For the functions and settings related to the communication between the DeviceNet master unit and CPU unit, refer to the manuals shipped with your master unit or CPU unit. Configuring the Master Unit The following configurations are required connect the NU-DN1 to the DeviceNet master unit. Slave attribute settings Configure the master unit with the communication form, I/O size, and other information about the slave units. You can also configure the settings by importing the EDS file of the NU-DN1 into the configuration software for the master unit. 2 Connection and Configuration Reference The EDS file can be downloaded from the KEYENCE web site: Memory allocation settings Configure the memory areas required for exchanging data through I/O communication. Do this using the configuration software of the master unit. Point The memory allocations must be reconfigured if the number of connected sensors is changed, because the memory area reserved in the NU-DN1 may change. Reference Where multiple slave units are connected, the memory allocation for each slave unit is done automatically based on the specified starting address. The allocation information for each slave unit can be checked using DeviceNet configuration software. 2-9

26 2- Communication Settings Configuring the NU-DN1 Use the following procedures to configure the data link of the NU-DN1. 2 Operation mode setting switch Connection and Configuration Address setting switch Setting the node address Using the address setting switch, set the DeviceNet node address to be assigned to the NU-DN1. Default value: 6 Setting range: 00 to 6 When setting the node address of the NU-DN1 from the DeviceNet master unit, set it in the range of 64 to 99. The NU-DN1 enters PGM mode. Point When the NU-DN1 is set in the PGM mode and the power is turned on, the address of the NU-DN1 is the same as used when the NU-DN1was started last time. When an NU-DN1 in the factory default setting is set to PGM mode, the node address of the NU-DN1 is 6. Do not start multiple NU-DN1 units in factory default settings in the PGM mode, as that will result in a network error because of the duplicate node addresses. 2-10
