Hi Zbynek

Just to let you know, I resolved my problem.

It was a known problem on Rockwell product side, a update and reboot cured the problem.


Thanks for your time and support.

Hi

I am willing to try the OPC Analyzer, could you provide me with a download link.

Not about blaime, I just want to understand why the errors occurs or get a logical explanation.

Hi

I am using Rockwell Automation FactoryTalk Gateway.

There is no such server configuration.

Hi Zbynek

I have a weird error and I would like some advice.

I have a variable in a PLC called OPC_To_PLC, variable type is DINT and its a array with size 10.

Basically if I try and write a value larger than 127 into the array I get an exception error, "Out Of Present Range". The PLC data type is definitely a DINT so I cannot understand why it wouldn't work.

Further to this, I created a new variable OPC_2_PLC, variable type is DINT and its array size is 10, i.e. its the same apart from the name. When writing to this variable name it works so I can only assume somehow or somewhere OPC_To_PLC is defined as a SINT.

To clarify it wasn't my code I have see the same symptons in your sample application.

I have a work around but I would ask for a sensible explanation - that's if there is one!
