5 B-62714EN/04 SAFETY PRECAUTIONS 2 GENERAL WARNINGS AND NOTES WARNING 1 Before operating the machine, thoroughly check the entered data. Operating the machine with incorrect data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 2 Never attempt to perform a production run, such as actually machining a workpiece, without first checking the operation of the machine. Before starting the machine for a production run, ensure that the program command values, offsets, current position, external signals, and other settings are suitable for the operation to be performed. Also check that the machine operates correctly by performing a trial run using, for example, the single block, feedrate override, or machine lock function or by operating the machine with neither a tool nor workpiece mounted. 3 Ensure that the specified feedrate is appropriate for the intended operation. Generally, for each machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the intended operation. Refer to the manual provided with the machine to determine the maximum allowable feedrate. If a machine is run at other than the correct speed, it may behave unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 4 When using a tool compensation function, thoroughly check the direction and amount of compensation. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. s - 3

6 SAFETY PRECAUTIONS B-62714EN/04 WARNING 5 The parameters for the CNC and PMC are factoryset. Usually, there is not need to change them. When, however, there is not alternative other than to change a parameter, ensure that you fully understand the function of the parameter before making any change. Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 6 Immediately after switching on the power, do not touch any of the keys on the MDI panel until the position display or alarm screen appears on the CNC unit. Some of the keys on the MDI panel are dedicated to maintenance or other special operations. Pressing any of these keys may place the CNC unit in other than its normal state. Starting the machine in this state may cause it to behave unexpectedly. 7 The operator's manual and programming manual supplied with a CNC unit provide an overall description of the machine's functions, including any optional functions. Note that the optional functions will vary from one machine model to another. Therefore, some functions described in the manuals may not actually be available for a particular model. Check the specification of the machine if in doubt. 8 Some functions may have been implemented at the request of the machine-tool builder. When using such functions, refer to the manual supplied by the machine-tool builder for details of their use and any related cautions. Refer to the following two examples. <1> Some machines have a tool replacement device that operates when a tool feature is executed. When the user is working near the device, he or she may touch it. Execute tool features in a place sufficiently away from the tool replacement device. <2> Many auxiliary features cause machine operation such as rotation of the spindle. Understand the operations of auxiliary features before using them. s - 4

7 B-62714EN/04 SAFETY PRECAUTIONS NOTE Command programs, parameters, and variables are stored in nonvolatile memory in the CNC unit. Usually, they are retained even if the power is turned off. Such data may be delated inadvertently, however, or it may prove necessary to delete all data from nonvolatile memory as part of error recovery. To guard against the occurrence of the above, and assure quick restoration of deleted data, backup all vital data, and keep the backup copy in a safe place. s - 5

23 B-62714EN/04 SPECIFICATIONS 1.I/O LINK-II I/O FUNCTION 1.2 MASTER FUNCTION The master function consists of the following function: (1) DI/DO data transfer function NOTE FANUC I/O Link-II (master function) uses the following services of OPCN-1: (1) Initialization service (2) Input/output service (3) Reset service

24 1.I/O LINK-II I/O FUNCTION SPECIFICATIONS B-62714EN/ SLAVE FUNCTION The slave function consists of the following functions: (1) DI/DO data transfer function (2) Global I/O transfer function (FANUC unique function) (3) Capability of turning on and off the power to a slave station at any time without affecting communications performed by other devices NOTE FANUC I/O Link-II (slave function) uses the following services of OPCN-1: (1) Initialization service (2) Input/output service (3) Reset service About the global I/O transfer function: The figure below shows DI/DO data transfer performed between a master station and slave stations #1 to #N. Suppose that a slave station using the global I/O transfer function is a local slave station, and the other slave stations are remote slave stations. Then, the local slave station (#2) can receive DO data sent from the master station and can also receive DO data sent to the master station from the remote slave stations. So, the local slave station can make a ladder reference. Master station Slave station #1 [Remote slave station] Slave station #2 [Local slave station] Slave station #3 [Remote slave station] Slave station #N [Remote slave station] DO data from slave stations #1 to #N (excluding #2) NOTE The global I/O transfer function is not a function defined by OPCN-1 but a FANUC unique function. This function can be used even when the network includes products of other manufacturers (even as a master station). In this case, however, the size of data that can be transferred is limited

The I/O Link-II function does not exchanges data in synchronism with a ladder program, so that the function does not guarantees the concurrency of DI data consisting of 2 bytes or more. This means that when a ladder program reads 2-byte DI data, for example, the higher byte and lower byte of the data may be updated at different timings. Example where concurrency is not guaranteed When the 2-byte data 1234 (hex) is entered from the I/O Link-II board to the area R0300 set to the value 0000 (hex), the ladder program may read the value 0034 (hex). DI data 34 R area of the PMC R R If the ladder program reads R0300 during this period, 0034 (hex) is read. R Example of countermeasure: Control using synchronization flags Concurrency can be guaranteed by providing a synchronization flag before and after multi-byte data and synchronizing the data with the flags. An example of guaranteeing the concurrency of 6-byte data is given below. (1) Data structure A synchronization flag is prepared at the byte position preceding the 6-byte data and at the byte position following the 6-byte data, thus allocating an 8-byte area in total. R0099 Synchronization flag 1 R0100 : Data section R0105 R0106 Synchronization flag 2 (2) Processing on the data write side The data is updated using the procedure below. 1 Synchronization flag 1 is incremented. 2 The data section is updated. 3 The same value as set in synchronization flag 1 is set in synchronization flag

CAUTION If the size of the data section to be synchronized is increased by combining multiple bytes of data, synchronization may become difficult. In such a case, divide the data section on a variable-by-variable basis before setting synchronization flags
