Diagnostics XBT Error Indication Overview Question Marks and Crosses Hash Characters Blinking Alphanumerical Fields XBT terminals indicate errors in different ways e by displaying question marks on alphanumerical fields by displaying crosses for graphic objects e by displaying hash characters in alphanumerical fields e by blinking alphanumerical fields e by issuing error messages The following paragraphs list these three errors and their possible reasons of your XBT terminal a transmission error has occurred To fix this error check the following If Then question marks are displayed verify that all cables are correctly connected question marks are displayed the XBT terminal may have received no response from the PLC Hash characters displayed in alphanumerical fields on your XBT terminal indicate that the value to be displayed is too long for this alohanumerical field and cannot completely be displayed The value 100 can for example not be displayed in a 2 digit alohanumerical field To fix this problem enter a shorter value or adapt the size of the alphanumerical field so that it can display any of the possible values of the PLC variable Blinking alphanumerical fields on your XBT terminal indicate that the value of this field has exceeded or fallen below a user defined threshold 33003992 09 2007 27 Diagnostics Error Messages E
