ASCII character coding

The 8 bit ASCII character coding in the Modbus registers
3.3.12.2
ASCII string syntax
Syntax:
C(model;type;serialNo;location;swRev;hwRev)H(swRev;hwRev)0(
swRev;hwRev)1(swRev;hwRev)2(swRev;hwRev)3(swRev;hwRev)4(swR
ev;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 local HMI 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 signalled 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.
The data within the C section is restricted to certain maximum lengths. For example, the
user definable IED location is here restricted to a maximum of 34 characters. If the IED
location information on system level contains more characters, only the 34 first characters
are displayed.
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.
