Hello,

Thank you for contacting National Instruments

I�m not completely clear on your issue. Here are a few questions that should help me answer your questions better:

1) What version of Lookout are you using?
2) Are you using the Lookout Tiway object? If not, what Lookout object are you using?
3) How are you receiving this error message? Is this being received from the Alarms Window?
4) Has this communication with your Tiway ever worked? If so, what has changed since stopped working?
5) Can you give me more information on the way you are connecting and communicating to the Tiway? Also, can you tell me what model of PLC you are using?
6) What data members are not reading correctly from the Tiway object? Which data members, if any, are reading correctly?


I have included a link to a Knowledgebase article which may help out in diagnosing the communications from the Tiway object:
How Do I Create a Communication Diagnostic File for the Lookout Tiway Object?

I hope this helps. Please let me know the answers to the above questions.

I posted the original question about the Lookout host command error. It turns out the constant memeory of the Siemens plc needed to be increased on the unit the Lookout was being connected to. Evidently my Lookout application addressed a higher memory address in constant memeory than the PLC was configured to use.

Thanks RWW

Ken S. The version of Lookout was 5.0 I was using the Lookout object Tiway. I recieved the error in the Lookout alarm window. The communications between the Siemens PLC (555-1105) did work on some points.

Tnx RWW
