Micro 800 series to AB 1400 Series communication
Communicating over DF1 Radio modem (using 870E with DF1)
Using the CIPGENERIC instruction.
To address a location on a 1400 you need
Service USINT Service code:
1 – 127
Class UINT Logical segment’s Class ID value:
1 – 65535
Instance UDINT Logical segment’s Instance ID value:
0 – 4294967295
Attribute UINT Logical segment’s Attribute ID value:
1 - 65535, 0 - No Attribute ID used
MemberCnt USINT Members ID count. Maximum Member ID values used:
1 - 3, 0 - No Member ID used
MemberId UINT[3] Member ID values:
0 - 65535
Does this work?
Is there a table or some way to tell what the codes are for example for N7:x data points on the 1400?
manual gives example of getting Catalog ID but does say how these numbers were determined
Going the other way.. 1400 ---> 870E I believe the only way this can be done is with modbus so can't use DF1 comms. However if anyone knows something I don't on this feel free to share.
