PLC2Base
This is the PLC-2 address, in octal format, where the first SB file element (N12:0) is located.
Default is 200 (oct). To calculate the PLC-2 address for other elements, see PLC-2 Unprotected
Messages (page 21). Use the A-B Unsolicited Messages Diagnostic Screen (page 40) to verify
that the PLC-2 address used returns the data intended.
PLC2ReverseFloat
This parameter determins the encoding of a PLC-2 representation of a floating point number.
Possible values are:
0 Default. IEEE 32 bit encoding, most significant word first.
1 IEEE 32 bit encoding, least significant word first. A message rung in a PLC-5,
using “PLC-2 unprotected read” or “PLC-2 unprotected write” requires a 1 in this
entry for correct floating point representation.
2 Integer/Fraction split. Integer part in the first word, fraction in the second, with
four decimal places implied

SAMPLE SUPERB.INI
The following is a sample SUPERB.INI with comments that helps explain especially the entries
needed to use a multiport adapter. The adapter used was a FASTCOM422/4. See also Install
RS-422 multiport adapter, if needed, page 5.
