    • Hi, I have a problem with a CPU unistream. I downloaded the operating system and I installed it in the plc. but now appear in the display "CPU error detected" and the plc not recognized the cpu.   Can someone tell me how to solve the problem? Thank you      
    • You can take the sampler file and use the Data Converters Suite in order to export the data to Excel (So you can see the exact value at a specific time).  
    • I am trying to control a BACnet device via a GW-BAC1 gateway but it doesn't work. The device has 8 digital outputs and 8 digital inputs. See the attached YABE display. I am just trying to control the first digital output. Does any of the information in the YABE display go into the GW-BAC1 config file? Here's my config file: //================================================================================

    • In the provided example "unistream_070_Bacnet_TCP", there's a global of type "Modbus Remote Slave". When I try to add another global, "Modbus Remote Slave" doesn't appear as a type option. Since my PLC is going to be the slave, should there be a type "Modbus Remote Master"?
