Fieldbus Builder tool
I have created a HART signal using AI845 ( 11. Modbus > 101 AI845 ) . I have all regular signals. However, the Asset monitoring of HART signals have not report correctly . It show "bad.last.unknow.value" at Asset Report aspect. Regarding , the bad quality of HARTsignals , there are few questions I would like to ask:
1. Do I have to run FFB tool ? Can I run it on running controlller ?
2. Do i need to turn Enable communication parametter at AI845 card after runing FFB tool ?
3. Is there any thing I miss which cause the HART asset monitor have not reported ?
Thanks in advantage
For hart protocol to work properly u have to do the following.
1.you have to enable the tool routing in the controller hardware. And don't change the max no of connections max it should be 50 only default 20.
2.cinfigure fbb opc server.
3.hart device objects will be configured by using device management tool.
4.configure device objects in hardware channel and enable the communication. And run upload ensure don't download until unless u knows the data Else it will change the parameters in the running device.
