106 [3] Error Messages This section explains the messages that appear when an error has occurred in the GP unit during RUN mode. The origin of the problem behind each error message is explained with appropriate ways of disposing of the error. After a problem has been solved, unplug the GP's power cable and then reattach it. If there is more than one error, the GP displays the error message for the last error detected. (1) Error Message List The error messages listed below appear on the GP unit. Instructions on how to find and solve problems causing these error messages are explained on the following pages. -SYSTEM ERROR -ILLEGAL ADDRESS IN SCREEN DATA -UNSUPPORTED TAG IN SCREEN DATA -PLC NOT CONNECTED (02:FF) and (02:F7) -PLC NOT RESPONDING (02: FE) -RECEIVE DATA ERROR (02:FD) -GP STATION NO. DUPLICATION ERROR (02:F9) -NETWORK ADDRESS ERROR (02:F8) -PLC COM. ERROR -SCREEN MEMORY DATA IS CORRUPT -CLOCK SETUP ERROR -SCREEN TRANSFER ERROR -SCREEN TAG LIMIT EXCEEDED -OBJ.PLC HAS NOT BEEN SETUP 3-12

107 -ILLEGAL ADDRESS IN SCREEN DATA Caused by an overlap of addresses. Following the error message, error codes, as listed below, appear. If the error cannot be fixed, please report the error code and details on how the error developed to your local GP distributor. ILLEGAL ADDRESS IN SCREEN DATA (00B:***:***) Error No.1 <Table 1 Overlapping Addresses> Error No.2 Table 1 If addresses of the data area in the column B overlap seeing from the data area in the column A, an error message corresponding to each displays. Error No.1 Error No.2 A B 0C1 0C2 0C System Data Area Trend Graph Alarm Messages Trend Graph S tag System Data Area Alarm Messages S tag Trend Graph S tag K tag 0C9 19B Alarm Messages Trend Graph S tag K tag Overlapping addresses, other than the ones mentioned above, can also cause the Illegal Address message. E.g. When the starting address of the System Data Area is set to 100, and the tag below is setup: The N-tag is set to 32 bits, meaning it uses two word addresses. Since the first address is 99, the second address must be 100. Address 100 is ineligible for use since it has already been used for the System Data Area. *1 For Trend Graph, Alarm Messages, Tag Reference Manual. 3-13

108 -UNSUPPORTED TAG IN SCREEN DATA A list of tag(s) in use that are unsupported by the current GP version appear with this error message. Setup the tags to correspond with the GP. For the details of tags, Tag Reference Manual -PLC NOT CONNECTED (02:FF) (02:F7) Displays when communication with the PLC has stopped for over 60 seconds, when there is a transmission timeout error, or when there is excess noise. Check the correspondence cable wiring and connect correctly. -PLC NOT RESPONDING (02:FE) Displays when there is a Reply Timeout Error, or when there is excess noise. The origin of the problem and the matching solutions are listed in the table below. ORIGIN The power for the PLC host is not activated. GP unit INITIALIZE s etup (Setup I/O, PLC Setting) is incorrect. The host and GP powering up process was incorrect. The Communication Cable was not connected properly. SOLUTION Turn On the host's power switch. Setup the unit correctly and match up with the current host and Communication Cable. Turn the host's power On first, wait 2 to 3 seconds, then power up the GP unit. Check the Communication Cable wiring and c onnect it up properly. -RECEIVE DATA ERROR (02:FD) This problem arises as a result of one of these three: -There is a problem in trying to receive the data. -The connected PLC and the PLC setup for the data is different. -Noise These errors, except for noise, appear when the Communication Cable is pulled out when the GP unit is On, or when normal communication operations are being run, but the GP has been powered Off, then back On. To solve the problem, simply begin running transmissions again. When the error is a result of noise, correct any improper connections. 3-14

109 -GP STATION NO. DUPLICATION ERROR (02:F9) This error appears for one of two reasons: -The GP number is same as the station number for another GP. Check all the GP station numbers. -In the middle of correspondences, the PLC power has been turned On/Off. Reset the power on the PLC and GP. -NETWORK ADDRESS ERROR (02:F8) The SIO address setup for the GP is different from other GP's. Check the address setup for all the GP's. 3-15

110 -PLC COM.ERROR Appears when the address setup for tags exceeds the address range on the host side. Check the Error Number that appears and use the following table to solve the problem. PLC COM.ERROR ( 02 : ** ) Table2 C o n st a n t Value <Table 2 Error No. List> Error # Origin Solution FC The communication settings for this unit Fix the SIO communication settings to match the host. and the host do not match. FB Memory to Memoty type. When using Memory to Memory Type: Siemen's PLC Series Set the addresses within the set range of the System Data Area. (0 to 2047) When using Siemen's Series PLC Type: Set up the Data Block in the PLC where the System Data area is set. FA Address range error Set the addresses within the allowable range. 53 When using a Matsushita Electronics Decrease the number of tags on the screen. PLC, and there are too many screen tags, the PLC will not receive data. 51 In the case of Fuji Electric PLC Setup the addresses in a device range that exists. The tag address, Trend graph data storage address, Alarm message Registry address, and the like, do not exist in the PLC's internal device. Others The Error Number for each PLC is displayed. Look up the Error Number in the indicated PLC manual. Or, report the Error Number to the PLC maker. 3-16

111 -Disregard the above table if Error Number 51 appears and you are using a PLC other than Fuji Electric. Look up the error contents in you PLC manual and follow the instructions therein. -Disregard the above table if Error Number 53 appears and you are using a PLC other than Matsushita Electronics. Look up the error contents in you PLC manual and follow the instructions therein. -In Hitachi's HIDIC H (HIZAC H) Series, the error code is divided into 2 bytes, whereas the GP Error Number is composed of 1 byte codes. E.g. Reply Command Return Code Display Error When the displayed error number is 8*, or 5*, use only the left column as the error number. -In Toshiba's PROSEC T Series, the Error Code is 4 places long; on the GP, Error Numbers are displayed and changed into Hexadecimal. E.g With the Allen-Bradley PLC-5 and SLC-500 Series, the EXT/STS error codes have been re-mapped to start at D0HEX, so they will not conflict with other error codes. When looking up the error number in the PLC manual, subtract D0 h from the GP error code to find its error value. E.g. GP Error Code PLC Error Code D1 -> 01 EA -> 1A 3-17

112 -SCREEN MEMORY DATA IS CORRUPT Displays when the checksum of the screen memory data does not match because of a corruption in the screen files. Error codes, as shown below, follow the error message. By referring to the error code, check the screens that have errors. When a screen file has been corrupted, delete that file, and make a new one (or recall a backup copy if available). SCREEN MEMORY DATA IS CORRUPT (**** : ****) The number of screens that have errors (Decimal) The Screen Number that has an error. (Displays only one per Screen Number.) -CLOCK SET UP ERROR This message displays when the lithium backup battery's voltage for the internal clock runs. To reset the error, you need to turn the GP's power OFF and then ON again. Leave the GP ON continuously and the battery's charge will become sufficient for backup after 24 hours, and will be fully charged in approximately 96 hours. If the battery is incorrectly replaced, the battery may explode. To avoid the danger, please do not replace the battery yourself. When the battery needs a replacement, please consult with your local GP distributor. After changing the backup battery, set up the internal clock. Users Manual Chapter 5, Initialize -The life span of the backup battery depends on the battery's ambient temperature and the amount of current being charged and used. The table below gives a general indication of how long the battery will last.

Try re-transmitting the screen data. 3-18

113 -SCREEN TAG LIMIT EXCEEDED (For GP70 Series, max 256, For GP2000 Series/GP77 Series, max 384) When tags are setup beyond the tag limit, these tags are made invalid. Tags are invalidated from the end tag, in the opposite order in which they were registered. Plus, when tags involve registered Windows and loaded screens, they are invalidated in this order: Window Registry, Load Screen. Further details for when multiple displays are set to one screen. 1. Invalidate registered windows from the end screen. 2. Invalidate loaded screens from the end screen. Check invalidated tags and reduce the tag number. 3-19

114 -OBJ.PLC HAS NOT BEEN SETUP The host PLC setup in SOFTWARE's does not match the PLC in use. Use the Error Code that follows the error message to select the proper PLC type in the GP and correct the INITIALIZE setup. PLC Connection Manual OBJ.PLC HAS NOT BEEN SETUP (x x) The PLC number (Hexadecimal) written to the System File *Table 3 <Table 3 Example of OBJ.PLC Numbers (Hexadecimal)> 3-20

115 (2) Error Messages-Details -SYSTEM ERROR Indicates a fault in the basic operations of the GP. Following the error message, an error code, as shown, will appear. Report the error number, and details on how the error developed, to your local GP distributor. SYSTEM ERROR (03: x x ) Displays when a PC transferred file cannot be rebuilt. 03 : x x Error No. C on stan t Value SYSTEM ERROR (xxx : xxx : xxx) Displays in RUN mode when a file cannot be rebuilt. x x x : x x x : x x x Error No.3 Error No.2 Error No.1 -Check if the GP's power Cord and the Input signal line have been wired separately from each other. -Check that the FG line has been grounded correctly, according to your country's standards. -Re-send the screen data from the PC to the GP. -If other types of communication errors have also occurred, try to correct those problems also. [RECEIVE DATA ERROR] [PLC COM.ERROR] If the above mentioned methods do not solve the problem, please contact your local GP distributor. When the GP changes to OFFLINE mode during RUN mode When the GP changes to OFFLINE mode without the user first pressing, there is a possibility that the screen data has been damaged. In this case, after the SYSTEM ERROR displays, the screen automatically reverts to OFFLINE mode after about 10 seconds. Run the INITIALIZE MEMORY command and transfer the GP screen data again from your PC. 3-21

116 In most cases, system errors are related to the problems mentioned below. 1) Environment Related Problems If an error occurs which has no apparent connection to the GP's current operation, the error may be due to the condition of GP's operating environment. This can include noise or electrostatic interference in the power code or the communication line. In this case you need to check if the power code and the communication line wiring and FG grounding are correct. 2) Screen Data or Project Data Related Problems If an error seems to be caused by a particular GP operation, the error may be related to the screen or project data transferred to the GP. In this case, try sending screen data via the FORCE SYSTEM SETUP feature, which will transfer both the screen data and the project data to the GP. 3) GP Unit Related Problems If disconnecting and then re-connecting the power code corrects an error, the problem may not be related to the GP unit itself. However, to identify if the GP unit has any problems, run the OFFLINE mode's SELF-DIAGNOSIS program. 4) Peripheral Equipment Related Problems If an error occurs only during printout, there may be a problem with the printer. Check the printer cable wiring and the FG line as well as the printer itself. 5) When a communication error occurs continuously If a communication error occurs continuously, the GP may define the error as a system error. In this case you need to solve the problem causing the original communication error. 3-22
