Port Settings Changes
DNPMAP This setting has been eliminated. Maps are now always custom.
RPADR01–RPADR06 REPADR1–REPADR6
RPADR07–RPADR10 No longer exist.
DNIP01–DNPIP06 DNPIP1–DNPIP6 Note that HOSTn aliases may have been used instead of actual IP addresses.
DNPIP07–DNPIP10 No longer exist.
DNPTR01–DNPTR06 DNPTR1–DNPTR6
DNPTR07–DNPTR10 No longer exist.
DNPUP01–DNPUP06 DNPUDP1–DNPUDP6 The range is slightly more restrictive in the new implementation. The lowest
assignable port is 1025.
DNPUP07–DNPUP10 No longer exist.
UNSL01–UNSL06 UNSOL1–UNSOL6
UNSL07–UNSL10 No longer exist.
PUNSL01–PUNSL06 PUNSOL1–PUNSOL6
PUNSL07–PUNSL10 No longer exist.
DNPMP01–DNPMP06 DNPMAP1–DNPMAP6
DNPMP07–DNPMP10 No longer exist.
DNPCL01–DNPCL06 DNPCL1–DNPCL6
DNPCL07–DNPCL10 No longer exist.
ECLASSA CLASSA1–CLASSA6 Old setting allowed 0–3. New setting has OFF, 1–3. Old setting 0 is equivalent
to new setting OFF.
ECLASSB CLASSB1–CLASSB6 Old setting allowed 0–3. New setting has OFF, 1–3. Old setting 0 is equivalent
to new setting OFF.
ECLASSC CLASSC1–CLASSC6 Old setting allowed 0–3. New setting has OFF, 1–3. Old setting 0 is equivalent
to new setting OFF.
DECPL DECPLA1–DECPLA6
DECPLV1–DECPLV6
DECPLM1–DECPLM6
ANADB ANADBA1–ANADBA6
ANADBV1–ANADBV6
ANADBM1–ANADBM6
16BIT AIVAR1–AIVAR6 The old setting let one pick between 16-bit and 32-bit variations. The new set-
tings let one pick any of the 6 valid analog input variations. The old setting of
16 is equivalent to 2 and 32 is equivalent to 1.
STIMEO STIMEO1–STIMEO6 The new settings accept integers only.
DNPPAIR This setting no longer exists. Selections of paired controls are now a function of
configuring the map.
DNPINA DNPINA1–DNPINA6
NUMEVE NUMEVE1–NUMEVE6
ETIMEO ETIMEO1–ETIMEO6
URETRY URETRY1–URETRY6
UTIMEO UTIMEO1–UTIMEO6
PMOIPA1–PMOIPA2 PMOIPA1–PMOIPA2 Note that HOSTn aliases may have been used instead of actual IP addresses.
PMOUDP1–PMOUDP2 PMOUDP1–PMOUDP2 The range is slightly more restrictive in the new implementation. The lowest
assignable port is 1025
