I/O SIGNALS CONVENTIONS

8.7.1

Solid State Relay Output Signals (OUT0 to OUT7)

The solid state relay output signals drive relays in the machine (power

magnetics cabinet) side and indicator LEDs.

(1) Solid state relays

(a) Maximum load current at output-on

250 mA: Up to three outputs set to on

125 mA: Eight outputs set to on

(b) Saturation voltage at output-on

Not more than 6 × IL [V] (IL: load current)

30 VDC max. even for instantaneous voltage

(d) Leak current at output-off

Not more than 100µA

(2) Output circuit

(3) Always install spark arresters when inductive loads such as relays

are connected in the machine. Insert the spark arresters as near the

load as possible (less than 20 cm). When capacitive loads are used

in the machine, insert current limiting resistors in series with the

loads to prevent the instantaneous current and voltage from

exceeding the rated values.

(4) If a lamp is turned on by a solid state relay output, the resulting

surge current may damage the solid state relay. Thus, as shown in

the figure below, provide a protective resistor to prevent the

instantaneous current and voltage from exceeding the rated values.

DC Input Signals (ME and CSP)

The DC input signals (such as relay contact signal) are sent from the

machine (control circuit) to the pulse counter module.

(1) Input conditions

Off voltage and current: 6 VDC or less, 2 mA or less

Response time: 20 ms or less

(2) Voltage and polarity

+5-V Output from JA9 Connector

• A voltage of +5 V on the JA9 connector of this module is the

output of the counter module (300 mA maximum).

It is necessary to satisfy Table 4.4 in Section 4.4, "Required

Current", though.

Example: Assuming that 100 mA is supplied from the +5-V pin

of the JA9 connector:

170 + 0.3 × 100 = 200

Thus, the required current is 200 mA.

Counter Presetting and Counting

(1) Presetting a counter value

(using the external signal MKS)

To preset a counter value, using the MKS signal, follow this

procedure:

(a) Reset the MH (marker hold) signal.

(b) Preset a value in the counter at the rising edge of the MKS

signal.

The MH signal is set at the same time the counter is preset with

data.

(a) Resetting the MH signal

For mode A, both methods, (i) and (ii), are usable. For mode

B, method (ii) is usable.

(i)

Resetting the MS bit (bit 6) of the CTRL (control)

Setting Data

Data for some models (such as the FS15 and FS18) is in the opposite

order to that of the NC data. In this case, convert (rearrange) the data in

byte units.

[Example of setting]

CTRL

DTOH

PRS

SELECT

DTOM

DTOL

Example 1 :

To preset the counter preset register with a specific value (the

counter is also set to preset value), follow the steps below.

(1) Preset the DTOH, DTOM, and DTOL with a desired value.

(2) Set SELECT to 001.

(3) Reverse the setting of the PRS (from 0 to 1 or from 1 to 0).

(4) Wait for two scanning periods.

• Another method for presetting the counter is to use the

MKS external signal (see Subsection 8.8.2). It takes a

maximum of 5 ms to preset using the first method, while

it takes only a maximum of 100 µs to preset using the

MKS external signal.

Example 2 :

To set the comparison control register with the setting (0 or 1) of

CMA, CMB, and CMC, follow the steps below.

(1) Set DTOH bits 0, 1, and 2 to the desired data.

(2) Set SELECT to 000.

(3) Reverse the setting of the PRS (from 0 to 1 or from 1 to 0).

(4) Wait for two scanning periods.

Example 3 :

To set comparison register B to a desired comparison value,

follow the steps below.

(1) Set DTOH, DTOM, and DTOL to the desired comparison

value.

(2) Set SELECT to 011.

(3) Reverse the setting of the PRS (from 0 to 1 or from 1 to 0).

(4) Wait for two scanning periods.

The result of comparing comparison registers A, B, and C with the

pulse counter is output via OUT0 to OUT2 of connector C49 of this

counter module (A → OUT0, B → OUT1, and C → OUT2).

Their output status is output via OUT0 to OUT2 of the LED indication

panel (A → OUT0, B → OUT1, and C → OUT2).

The result of comparison can be confirmed by checking STTS bits 0, 1,

and 2 (CMPA, CMPB, and CMPC) with the PMC.

Reading Data

The CNTS and STTS are two of the four input bytes. The most

significant bit, TRA, of the CNTS and the most significant bit, TRB, of

the STTS can be used to determine whether the count data is correct. If

both TRA and TRB are 0 or 1, the count data is correct. The

time during which the TRA and TRB bits have a different value from

each other is abut 2 msec.

In almost all cases, both TRA and TRB will be 0 or 1 when you view the

diagnostic display. (Do not determine that the data has not changed

because of the fact that the TRA and TRB do not become 0 or 1

alternately.) Note that the count data does not take a negative

value.

16 scan cycles after RUN.

To be specific, the following are output.

A comparison value for partition #5 is specified

18 scan cycles after RUN.

A comparison value of +1160 is used here. (A

range from +1120 to +1160 becomes partition

#5.)

A timing signal indicating TRA = TRB is generated.

If TRA = TRB = 1 or TRA = TRB = 0, R50.2

becomes 1.

The counter value is output to Y0001 to Y0003

when TRA = TRB.

CNTH → Y0001

CNTM → Y0002

CNTL → Y0003

The highest-order bit (TRA) is masked because

CNTH is 7-bit data.

NOTE

1 This sample ladder does not set a comparison value or output value for partition #6 and

above. If comparison and output values for these partitions are to be used, repeat the

same operation as for partition #6 and below by changing the SELECT value.

Be sure to invert the PRS bit (0 → 1 or 1 → 0) each time a value is specified.

2 The comparison and compare output values for each partition can be specified in any

order until CE = 1 (counter enable).

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).

PMC I/O Area

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 "output" are used in reference to the PMC. When input/output

addresses are assigned to the module, "/4" is used as the module name.

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.

(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.

(1) 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.

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".

This bit is used to specify channel switching for

4-channel manual measurement mode.

0: Channels 1 and 2
