ControlLogix Array Tag Index Off

Ignition
1

We are using a ControlLogix 1756-L72 with a DINT[2,18] array controller tag. Ignition tag index addressing for this array appears to be 1 off.
e.g. Ignition Array Tag reference [0,0] reads ControlLogix Array Tag [0,1]
Ignition Array Tag reference [0, 17] reads ControlLogix Array Tag [1,0]
Ignition Array Tag reference [1, 17] reads ControlLogix Array Tag [?](value is some large number apparently into another memory space)

RSLogix v19.11, Ignition v7.5.3 on Ubuntu 11.10

Please set the ABControlLogixTransport logger to “Debug”.
Next edit the device and save it (this will cause it to reconnect). Then send in the logs. Be sure to include the device name when you send in the logs.
