The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. [. . . ] Check this error code to determine the cause of the error and correct it. Flag ER (25503) ON Condition · Number of transfer words is not BCD. · Number of transfer words is 0 or 129 and above · When DM was set, the contents of DM was not 6656 and above, or BCD. · The transfer destination unit number is outside the permissible range. · The unit number for the transfer destination unit is for a Remote I/O Slave Unit. = (25506) The transfer has been completed without error. OFF Condition Anything else. 108 Writing Data with IOWR Section 5-4 5-4-4 Precautions when Using IOWR IOWR is an improvised instruction which transfers all data with a single instruction. It increases the transfer time for the data as well as the cycle time for the ladder program. The monitoring time for the cycle time should be adjusted as required. The transfer time is influenced by such factors as the model of the Programmable Controller being used, the ladder program, and the status of the Position Control Unit, and cannot be calculated easily. Refer to Appendix A Data Calculation Standards to transfer positioning sequences using a C200HX and a C200HW-NC413. It can be used as a model for setting cycle time monitoring time. Using IOWR, a maximum of 128 words of data in consecutive addresses can be transferred at one time. When using IOWR, be sure to transfer data in complete units, and do not start or end transfer in the middle of data. For example, with X-axis sequence #0, the data unit becomes three words consisting of addresses from 1000 to 1002. If the transfer is started or ended part-way through, ER Flag 25503 will be turned ON. When transferring the origin search high speed and origin search proximity speed settings, be sure to transfer both settings together. It is not possible to transfer only one of these settings. Note Depending on the execution timing of the IOWR instruction, it is possible that errors generated as a result of data check at the time of transfer may not be reflected at the CPU Unit. (Refer to 5-1 Transferring and Saving Data. ) 5-4-5 IOWR Program Example A sample program is provided below for writing the indicated speed data to the Position Control Unit. The beginning word address of the transfer data is to be DM 0500, and the other settings are as indicated. The data will be transferred to the Position Control Unit designated as Unit No. 2. Data Speed #0 Speed #1 Address (transfer destination) 1300 1301 DM (transfer source) 0500 0501 Setting 1000 5500 Position Control Unit (NC413, Unit No. [. . . ] Page 26: Information on connector models added.
