The following conventions are used to indicate and classify precautions in this manual. Failure to heed precautions can result in injury to people or damage to property. !DANGER !WARNING Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. [. . . ] (ISO 13850, Item 4-4; IEC 60204-1, Item 9-2) External Connection Diagram The status of the emergency stop switch's DPST-NC contact is output externally by hard-wired outputs via the Special Cable. NSH5 Emergency stop switch DPST-NC EMG1A1 EMG2A1 Special Cable EMG1 EMG2 Safety circuit EMG2A2 EMG1A2 Internal Memory or Host (PLC) Memory Allocation The emergency stop switch can be allocated any bit address in the internal memory or host (PLC) memory, and the ON/OFF status can be monitored at the allocated address. To specify the address in internal memory or host (PLC) memory that is to be allocated to the emergency stop switch, first select PT - System Setting in CX-Designer and then click the NS Handy Terminal Tab. In the Key Status Monitor Address Field, click the Set(1) Button for Emergency Stop (A), and specify the address to allocate. Allocate an address in internal memory or host memory to the emergency stop switch. The following points apply to the emergency stop switch allocation. · Addresses can be set in either internal memory or host memory. The NS Handy Terminal Tab can be selected only when the PT model is set to the NSH5. It cannot be selected for any other PT model. 37 Enabling Switch Section 3-3 3-3 3-3-1 Enabling Switch Overview In contrast to the emergency stop switch, which lets a worker intentionally stop the machine in case of an emergency, the enabling switch makes it easier to avoid danger with no conscious decision by a worker. When work is required in hazardous areas, e. g, during maintenance, devices with enabling switches provide an important safety measure by preventing unexpected operations from occurring while work is underway in the those areas. Manual operation of devices is permitted while the enabling switch is lightly pressed. At soon as a hazardous situation arises, however, operation is stopped if the worker instinctively either lets go of the enabling switch or grasps it more tightly. Some standards, such as the ANSI/RIA R15. 06 and CSA/Z434-03 Industrial Robot Standards and the ANSI/B11. 19 Machine Tool Standards, require the use of enabling switches. In EN 60204-1, enabling switches are not required but are recommended as auxiliary devices.

F6 F7 F1 F2 Hard-wired outputs F8 F9 F10 F3 F4 F5 Software NO conditions The status of function switches F1, F2, F6, and F7 is output externally by hard-wired outputs via the Special Cable. The status of the six remaining switches (F3, F4, F5, F8, F9, and F10) are output to internal memory or host (PLC) memory. External Connection Diagram The status of function switches F1, F2, F6, and F7 are output externally by hard-wired outputs via the Special Cable. NSH5 Function switches Four NO contacts output to external devices Special Cable F1 F2 F6 F7 PLC PLC PLC PLC F1 F2 F6 F7 SW COM Internal Memory or Host (PLC) Memory Allocation NSH5 function switches F3 to F5 and F8 to F10 can be allocated any bit addresses in the internal memory or host (PLC) memory, and their ON/OFF status can be monitored at the allocated address. To specify the address in internal memory or host (PLC) memory that is to be allocated to a function switch, first select PT - System Setting in CX-Designer and then click the NS Handy Terminal Tab. In the Key Status Monitor Address Field, click the appropriate Set Button, and specify the address that is to be allocated. 39 Memory Cards Section 3-5 Allocate addresses in internal memory or host memory to function switches F3 to F5 and F8 to F10. The following points apply to the function switch allocations. · Addresses can be set in either internal memory or host memory. The NS Handy Terminal Tab can be selected only when the PT model is set to the NSH5. It cannot be selected for any other PT model. 3-5 Memory Cards Memory Cards are used for storing and transferring screen data, log data, and system programs. For details on the transfer method, refer to the CX-Designer Help. 3-5-1 Memory Card Applications Memory Cards can be used at the PT itself. There are four kinds of log files, as shown in the following table. Alarm/event history Data log Operation log Error log Stores alarm/event history data that has been registered by CXDesigner. Stores error log data for when macros are executed. Log data is normally saved in internal memory that is backed up in the PT, but can also be saved in CSV file format. When log data is saved as a CSV file, it is stored on the Memory Card. [. . . ] Operation Check Perform the following steps to check if the project data settings have been correctly entered. (1) Connect NSH5 PTs 1, 2, and 3 to Removable Boxes 1, 3, and 8, respectively, and turn ON each Removable Box key switches. After each NSH5 PT starts, the initial display screen (screen 0) will appear. Also, the numbers 1, 3, and 8 will be stored in the Station Status Monitor Address, $W1000, for NSH5 PTs 1, 2, and 3, respectively. [. . . ]
