I want to develop an application in Visual Basic to communicate with my HI 3000 series controller via a PC.
Can I use either the -MB or the HI 3000-OPC options?
I am trying to install a Hardy Instrument and there are 9 wires:
2 for signal, 2 for excitation, 2 for C2®, 2 for sense and a shield wire.
What are the 2 sense wires for?
I'm trying to map values using DeviceNet and an HI 4060. The HI 4060 is at address 10 and shows as connected on the DeviceNet network. I have set the HI 4060 for slave mode and I am polling it with a 1756-DNB/A. I want to map the Net Weights and control to the DeviceNet scanner in the PLC. I also want to set the rate set points from the PLC. At this point I don't care about any other values. How do I set the mapping in the rate controller for this?
I have an application to replace a scale controller that controls two scales. I would like to use a HI 3030 on DeviceNet back to a A-B SLC 5/04. Can I connect two separate scales to a HI 3030 or do I need two HI 3030's? I want to be able to control the scales individually and would also like to do a traditional calibration from each scale.
Our application involves polling the HI 2151/30WC every 32 seconds for net weight. My HI 2151/30WC locks up and fails to communicate. What could be the cause?
