• IED model (max. 12 characters)
• IED type (max. 6 characters)
• IED serial number (max. 12 characters)
• IED location information (max. 34 characters)
• CPU card SW and HW revision numbers
• HMI card SW and HW revision numbers
• Slot 0 (X130) card SW and HW revision numbers
• Slot 1 (X120) card SW and HW revision numbers
• Slot 2 (X115) card SW and HW revision numbers
• Slot 3 (X110) card SW and HW revision numbers
• Slot 4 (X105) card SW and HW revision numbers
• Slot 5 (X100) card SW and HW revision numbers
• Slot 6 (X000) card SW and HW revision numbers
The IED does not need to contain cards in all slots nor does a specific
card need to include a CPU. The SW revision information is simply
omitted from the information string.

ASCII string syntax

Syntax
C(model;type;serialNo;location;swRev;hwRev)H(swRev;hwRe
v)0(swRev;hwRev)1(swRev;hwRev)2(swRev;hwRev)3(swRev;hwR
ev)4(swRev;HwRev)
• Parenthesis and semicolon ASCII characters are used as delimiters inside the
string.
• Section C(...) contains IED information and CPU version information.
• Section H(...) contains version information of the LHMI card.
• Sections 0(... ) to 4(...) contain version information of the additional HW
cards (slots 0...4).
• If an additional card does not include any version information, it is signaled with
a "-" (minus) character in the swRev field. If both swRev and hwRev are
signalled with "-" signs, the card in question does not exist in the IED.
