What does the blinking LED's signify on my HI 2151/30WC?

The weight deviation in the upper range on our HI 2151/30WC has been growing slowly over the last couple of months. I noticed that the status LED's for Alarm 1 + 2 were blinking alternatively with the LED's for 'Zero Track' + 'Motion' + 'CTR Zero'. The weight reading on the display was normal. After switching the module off and on the LED's were still blinking. Measurement of Excitation, Sense and Signal wires gave normal results. The unit was switched off and on once again, after which the LED's were not blinking anymore. Could you give me an explanation for the blinking LED's? Could this also cause a weight deviation?

Common PLC definitions

I'm starting a learning curve with your products and am not familiar with many of the acronyms used. Can you provide a definition for common PLC terms?

Why is my HI 2160RC always in REC mode when changing set points?

My 2160RC rate controller stays in constant REC when I send a new set point over my communications option. What is wrong?

Why can't I connect my HI 3000 unit to the DeviceNet Network?

We are having problems connecting our HI 3000 series controller (either an HI 3030, HI 3010, HI 3300 or HI 3600) to the DeviceNet network. Any suggestions?

What is the temperature range for the HI 2151/30WC?

Radiant heat from the sun seems to be causing the output of our HI 2151/30WC to fluctuate. This problem can be seen on our calculated flow. The flow is calculated using old data, fifteen minutes prior, minus current data multiplied by four to bring it to an hourly rate, then multiplied by one thousand to display in klbs/hr. The fluctuation is not as readily seen on the 4-20mA signal, but is definitely noticeable on the calculated flow. Does the HI 2151/30WC controllers have any history of heating problems in the electronics? We might install a heat shield to shade the instrument with a two inch air gap and increase the air flow if this will help?

Can I copy the parameters in my HI 3000 or HI 4000 series controllers?

How can I download all of the parameters in the HI 3000 series or HI 4000 series units so I have them if I need to set-up a replacement? Are there any parameters that do not get downloaded and need to be manually recorded? Do I need a specific software?

Why can't I communicate with the Ethernet I/P option on a HI 3000 series controller?

I have a HI 3000 series unit with the Ethernet I/P option installed. I have set up and can ping the address with good results. RS Linx also sees the unit on the network. But my Compact Logix processor shows a communications error and cannot get my unit online. What could be the problem?

Why are we getting an A/D error after we replace our old controller?

We are replacing our obsolete weight controller with a new Hardy controller and want to reuse the same load cells. Our traditional calibration methods are giving us problems when we try to set the span. I think it's because our old unit has 10 volts excitation and the Hardy unit has 5 volts excitation. When we run the mV calibration signal above 15, we get an A/D Conversion Error on our Hardy unit. Do we need to take our old calibration values and divide by 2?

Can we configure the HI 3030 printer port to send specific data upon request?

Can I remotely set the date & time on my HI 3030 with ControlNet?

On a HI 3030 with ControlNet is it possible to set the date and time remotely through the ControlNet connection?
