Dear ashadako, Good question. Here attached a document for your better understanding. That is Associated Values In Messages. It is process values/text list entries that are displayed as additional information with the message text. For a typical Alarm_8p block, it should have 10 associated values, SD (input), length 12bytes. It will displayed an extra word/figures/text in addition to the message text. The structure of an associated value The block consists of the number, the element type and the format instruction of the associated value. <No. of the AssociatedValue><ElementType><Format>@.. SD_1 = 1 (associate value) SD_2 = 2 SD_3 = 3. the list goes... %[i]x = Hexadecimal number with “i” digits %[i]u = Unsigned decimal number with “i” digits %[i]d =Signed decimal number with “i” digits %[i]b = binary number with “i” digits %[i].[y]f = Fixed point number Signed value of the form dddd: one or several numbers with “y” digits after the decimal point and “i” total digits %[i]s = Character string (ANSI string) with “i” digits Characters are printed up to the first 0 byte (00Hex). %t# = Access to text library [i] or [y] = just a digit , variable. The key word is "Associated Values" I hope my explanation is clear and useful for you. |

Yea, it comes from your CFC. I think you should have your "Source (CFC Name)" column in your alarm logging editor right? Trace the blocks from there? Hope you find this helpful. |
