[. . . ] Backing up the parameter data is recommended to allow easy replacement of faulty Units in the future. 3-2-3 Automatic restore function When a SmartSlice I/O Unit has been replaced, this function will automatically download (restore) SmartSlice I/O Unit parameter data that was previously backed up in the PROFINET IO Communication Unit. The following conditions are required to execute the automatic restore function: · DIP switch 1 (REGS) was ON when the power was turned ON, and the registered table is therefore enabled. · DIP switch 3 (ADR) was ON when the power was turned ON, and the automatic restore function is therefore enabled. · Parameter data has been backed up in the PROFINET IO Communication Unit. Function Overview 48 Unit functions Section 3-2 Power ON PROFINET Communications Unit #1 #2 #3 #4 DIP switch 1 was ON when power is turned ON and DIP switch 3 is turned from OFF to ON. Parameter data Parameter data is automatically restored only to the replacement Unit (same unit number, same model number, different serial number). Preparing Data Restore 1 Create backup data in the Communication Unit with the backup function. For details, see section 3-2-2 Backup function. 1 Turn OFF the SmartSlice I/O System's power supply and the I/O power supply. 2 Release the locks on the front of the SmartSlice I/O Unit that must be replaced and remove the terminal block. 3 Remove the main block of the SmartSlice I/O Unit and replace it with a new SmartSlice I/O Unit of the same type. 4 Mount the terminal block that was removed in step 2 and latch the locks that were released. 5 When the power is turned ON again, the Communication Unit will automatically detect the Unit that was replaced and download the backup data. The SmartSlice I/O Unit's TS indicator will indicate the results of the restore operation. · If the download was successful, the Unit will be reset automatically and join I/O communication normally. The I/O Unit's TS indicator will be lit green. · If the download failed, the I/O Unit's TS indicator will flash red. · If the connected Unit is the wrong model, the I/O Unit's TS indicator will be lit red. 1 Do not turn OFF the power supply or reset the PROFINET IO Communication Unit while data is being restored. The data will not be restored properly if the power is turned OFF. When a SmartSlice I/O Unit has been replaced with the power ON and the new I/O Unit joins I/O communication, the new Unit will be compared to the previous one and the parameter data restore operation will start automatically. While data is being restored, the PROFINET IO Communication Unit's TS indicator will flash green every 0. 5 second. The TS indicator will stop flashing (not lit) when the restore operation is completed. If the restore operation fails, the Automatic Restore Monitor Flag (bit 13 of the Communication Unit status flags) will be turned ON and the Communication Unit's TS indicator will be lit red for 2 seconds. Replacing a Unit 1, 2, 3. . . Note 2 3-2-4 On-line replacement function When one of the SmartSlice I/O Units connected to the PROFINET IO Communication Unit must be replaced, the Unit can be replaced without turning OFF the power. The Units can be replaced on-line because the SmartSlice I/O Units are made up of 3 blocks: the base block, main block, and terminal block. Function Overview 49 Unit functions Section 3-2 When replacing a SmartSlice I/O Unit, leave just the base block connected and replace the main block. I/O communication will continue with the other I/O Units even while the problem Unit is being removed and replaced. To keep the system online, leave the communications block connected. PROFINET Communications Unit #1 #2 #4 #3 Power ON If DIP switches 1 and 3 are ON, data is automatically restored to the replaced Unit. Unit being replaced Replacing a Unit 1, 2, 3. . . [. . . ] When an error response is returned for an explicit message, the number of bytes is always 0004 Hex. The station address of the Unit from which the command was sent is returned in hexadecimal. Source station address 93 Service Code For normal completion, the value when the left-most bit of the service code specified in the command turns ON is stored as shown in the following table. /i Function Write data Read data Reset Save Command service code 10 Hex 0E Hex 05 Hex 16 Hex Response service code 90 Hex 8E Hex 85 Hex 96 Hex When an error response is returned for an explicit message, the value is always 94 Hex. Data Error Codes Read data is included only when a read command is executed. The explicit message error codes as listed in the following table. /i Response code 08FF 09FF 16FF 15FF 13FF 0CFF 20FF 0EFF 10FF 14FF 19FF 2AFF Error name Service not supported Invalid Attribute value Object does not exist Too much data Not enough data Object state conflict Invalid parameter Attribute not settable Device state conflict Attribute not supported Store operation failure Group 2 only server general failure Cause The Service code is incorrect.
