5 What Is Averaging?

The followings are processed inside the thermocouple unit.

The example below is for 2 input channels. (The input range setting switches No.4 and No.5are turned OFF.)

EXAMPLE

The values for the 6 time measurements are averaged and the latest average is always

output to WX2 and WX3. (Max. and Min. value of the latest 8 time measurements areexcluded. Decimal fractions are rounded off.)

REFERENCE



When transferring the data from the thermocouple unit to the control unit, it is converted to 32-bit data including the channel information. Data for WX2 can be used as is, but the followingprocedure is required for WX3 data since its higher 2 bits are used as a conversion dataswitch flag.



FP0 Thermocouple Unit I/O Allocations and Sample Programs

15

PROCEDURE

1. When temperature data is negative, data for WX2 and WX3 are the 2 higherbit’s complement. Bit F for WX2 and bit D for WX3 is “1”. Make sure that that

is the case.

2. The higher 2 bits for WX3 are used as the conversion data switch flag.Therefore you need to mask the data. Mask the data using “00” when theconversion data is positive. Mask the data using “11” when the conversiondata is negative.

Data for CH3 WX3 → Data after masking

NOTE

X3D, X3E, X3F, WX2 and WX3 are changed depending on where the

7.1 Troubleshooting

PROCEDURE

1. Check whether the input signal lines are connected properly.

When the thermocouple is not connected properly or broken, K8000 is displayedfor thermocouple type K, J and T. K16000 is displayed for thermocouple type R.

2. Check whether the input range setting switch is set properly.

It specifies the allowed temperature range, the thermocouple type and the validchannel.

3. Use the program described on page 14 when the number of input channelsis higher than 4.

NOTES

1. The measurement range available for °C is not available for °F. For °Fthe upper measuring limit is set lower than for °C, since the digital

value (temperature value displayed) for °F is higher than that for °C .

2. When the thermocouple is broken, the digital value will change toK8000 or K16000 within 70 seconds. Using the program is a way toavoid a risk resulting from a broken thermocouple. A brokenthermocouple needs to be replaced.

3. Until conversion data is ready after the initial startup, the digitalvalue shows K8001 or K16001. These are not temperature data.Create a program so that they are not acquired as temperature data.

4. These are the settings of the input channel selection switch.

5. Conversion values for 6 time measurements (6 of the latest 8measurements, excluding the Max. and Min.) are averaged, so ittakes time for the digital value to be displayed due to the rapidtemperature change.

6. The control unit reads data from 2 channels in one scan. Read databy using the program described on page 14.

7. This changes depending on where the thermocouple unit is installed.(This is when the thermocouple unit is installed in the place of

expansion unit no.1.)
