Wonderware OI ABCIP G-2.0(v7.0) when used in conjunction with ControlLogix/CompactLogix/GuardLogix firmware v32 PLC can have some issues:

 

After a ControlLogix, CompactLogix, or GuardLogix controller running firmware v32.xxx is power cycled, it is possible that OI ABCIP communications do not resume. The OI ABCIP system tag, $sys$tagDBstatus, has a value of Uploading and the SMC log shows that the tag database upload procedure is not completing.

 

The solution is to do a download to the PLC, or upgrade the controller firmware to v32.014 or higher.

 

The issue is related to some new datatypes Rockwell introduced (but cannot be read anyway).

  • Unsigned data types: USINT, UINT, UDINT, ULINT
  • 64-Bit data types: LREAL, ULINT
