9 TEMPERATURE INPUT MODULE

9.1

OVERVIEW

A temperature input module is used to measure the temperature of machine tools and similar equipment.

The temperature input module can be either of the following, depending on the type of the sensor used.

• Thermoresistance-type temperature input module: ATI04A

• Thermocouple-type temperature input module: ATI04B

These modules can measure temperature on up to four channels. For the thermoresistance-type temperature

input module, either JPt100Ω or Pt100Ω can be selected. For the thermocouple-type temperature input

module, either K or J thermocouple input can be selected. This selection is made using the PMC user

program (ladder).

This temperature module uses an input/output area consisting of four bytes for input and the same number

of bytes for output. Each byte of the input/output area has the following meanings. The terms "input" and

Measurement Mode

This temperature module can operate in any of the following three measurement modes. The mode to use

can be selected using a user program (ladder).

(1)

2-channel measurement mode

This mode uses two channels, CH1 and CH2, for measurement. Data on each channel is updated every

0.3 s.

B-61813E/06

CONNECTION

9.TEMPERATURE INPUT MODULE

(2)

4-channel automatic measurement mode

This mode uses four channels, CH1 to CH4, for measurement. Input switching from CH1 and CH2

data to CH3 and CH4 data and vice versa is performed automatically. Data on each channel is updated

at a specified interval, say, every 0.5 to 10 s.

(3)

4-channel manual measurement mode

This mode uses four channels, CH1 to CH4, for measurement. The PMC can reference CH1 and CH2

data or CH3 and CH4 data at the desired timing.

Before setting the module setting data bit (NC READY (DO16)) to "1", set the following bits.

DO00 (LSB) to DO15 (MSB):

Channel switching period for 4-channel automatic measurement mode

These bits are set with a binary number representing the channel switching period for the

4-channel automatic measurement mode. They need not be set for the 2-channel mode.

The period can be varied in a range between 0.5 s and 10 s. When setting the bits, use a value ten

times the desired period.

(Example) 2 s → 20 (14h)

The valid data range is between 5 and 100 (64h). Any value out of this range is regarded as being

40 (28h), that is, 4 s. If nothing is specified, a period of 4 s is again assumed.

DO17 : Module type

This bit is set according to the type of the temperature module being used.

0 : Thermocouple-type module (ATI04B)

1 : Thermoresistance-type module (ATI04A)

DO18 : Sensor type

This bit is set according to the type of the temperature sensor being used.

• ATI04A

0 : Pt

1 : JPt

• ATI04B

0 : K

1 : J

DO19 : Reserved for future use

This bit must always be set to "0".

DO24 : Number of channels

This bit is used to specify the number of channels to be measured.

0 :

2 channels

1 :

4 channels (if 1 is selected, DO25 must also be used.)

- 141 -

9.TEMPERATURE INPUT MODULE CONNECTION

B-61813E/06

DO25 :

4-channel mode specification

This bit is used to select the 4-channel mode to be used.

0 : Automatic measurement (the period is specified using DO00 to DO15.)

1 : Manual measurement (a request is issued using DO22 and DO26 at every data read.)

Timing data

DO16 : NC READY

When the power is switched on, this bit is set to "1" to cause the module setting data to be set in

the temperature module.

The NC READY bit is enabled only once after the power is switched on. To rewrite the module

setting data, switch the power off and then on again.

DO22 : READ request

This bit serves as the timing signal used in 4-channel manual measurement mode. Setting the bit

to "1" issues a request for temperature data. When the input signal data READY signal becomes

"1", read the temperature data.

This bit need not be set for 2-channel mode.

READ request

1 s or longer

NOTE

After setting the NC READY bit to "1", wait for one second, and then set the READ

request to "1".

DO26 : Channel select

This bit is used to specify channel switching for 4-channel manual measurement mode.

0: Channels 1 and 2

1: Channels 3 and 4

NOTE

See Section 9.5, "Timing Charts," for concrete explanations about how to handle

the timing data.

CH1 temperature data, CH3 temperature data, or abnormality data

DI00 (LSB) to DI12 (MSB):

These bits indicate temperature input data (CH1/CH3) or abnormality data.

Temperature input data

The temperature input data is in binary. It is ten times the actual temperature.

Example

(83EDh → 1005 → 100.5°C)

The highest three bits are status signals.

For the thermoresistance-type module (ATI04A), the DI12 bit is a sign bit. (Negative data is represented in

two's complement.)

Example

(9F9Ch → -10.0°C)

The highest three bits are status signals.

Abnormality data

If an abnormality occurs in the input data or in the module, the DI13 bit (status signal) becomes "1",

resulting in the display changing from temperature input data to abnormality data. Abnormality data is

assigned to these bits as listed below:

DI00 : CH1 input out of scale--the current temperature falls outside the measurable range.

DI01 : CH1 input burn-out--the cable or connector has been detached.

DI02 : CH3 input out of scale--the current temperature falls outside the measurable range.

DI03 : CH3 input burn-out--the cable or connector has been detached.

DI04 : Cold-junction abnormality (only for thermocouple-type input module)—

The ambient temperature of the terminal unit is out of the measurable range (0°C to 55°C).

Alternatively, a wire between the temperature input module and the terminal unit is broken or

short-circuited, or the cold-junction compensation element is damaged.

DI05 : System error--the internal circuit is abnormal.

DI06 : Wrong module--other than the correct module has been installed.

Temperature input data

The temperature input data is in binary. It is ten times the actual temperature.

Example

(41F3h → 0499 → 49.9°C)

The highest three bits are status signals.

For a thermoresistance-type module (ATI04A), the DI28 bit is a sign bit. (Negative data is represented in

two's complement.)

Example

(5FFBh → -0.5°C)

The highest three bits are status signals.

Abnormality data

If an abnormality occurs in the input data or the module, the DI29 bit (status signal) is set to "1", resulting in

the display changing from temperature input data to abnormality data. Abnormality data is assigned to these

bits as listed below:

DI16 : CH2 input out of scale--the current temperature falls outside the measurable range.

DI17 : CH2 input burn-out--the cable or connector has been detached.

DI18 : CH4 input out of scale--the current temperature falls outside the measurable range.

DI19 : CH4 input burn-out--the cable or connector has been detached.

DI20 : Cold-junction abnormality (only for thermocouple-type input module)—

The ambient temperature of the terminal unit is out of the measurable range (0°C to 55°C).

Alternatively, a wire between the temperature input module and the terminal unit is broken or

short-circuited, or the cold-junction compensation element is damaged.

DI21 : System error--the internal circuit is abnormal.
