Chapter 1 Configuring the GX/GP

What Do You Want to Configure?

1. Measurement Source

You can assign DC voltages, thermocouples, RTDs, and on/off signals based on contacts and voltages to channels to take measurements. The measurement section is modular, so it can be expanded as necessary. Input signals are sampled at the scan interval and converted to measured values through A/D conversion.

Item Reference

Setting the scan interval →page 1-75 Setting the operation mode of a module (AI module: 2ch mode/10ch mode, DI module: normal/remote) Setting the A/D integration time of an AI module (analog input module) →page 1-77 Setting how to detect over-range values →page 1-75

2. Configuring Measurement Channels

You can set measurement conditions for each channel based on the input. You can calculate the difference between two input values or convert input values to measurement values with units that suit your purpose. Alarms can be generated when measured data exceeds or goes below specified values. Information that indicates alarm occurrence can be shown on the screen. Digital output channels (DO channels) can be used to transmit relay contact signals. You can change channel colors and assign tags to channels.

1.2 Configuring AI Channels (Analog input (including DI) channels)

Span Lower, Span Upper

Set the input range. The selectable range varies depending on the range setting. For the selectable ranges, see “Range Details.”

Note

• You cannot set the same value to Span Lower and Span Upper.

Calculation

When performing input calculation, set the calculation type.

• Linear scaling

Converts the unit to obtain the measured value.

Input value

0 V

–100°C

• Delta

Difference calculation. The measured value of the channel is set to the difference with

respect to the measured value of the reference channel.

Input value Measured value

—

Measured value on the reference channel

Measured value

Note

Difference calculation is executed even if the input type or range is not the same between the difference calculation channel and the reference channel. Differences in the decimal place and unit are ignored in the calculation. Then, the decimal place and the unit of the difference calculation channel are applied. Example 1: If the input value of the difference calculation channel is 10.00 and the measured value

Example 2: If the input value of the difference calculation channel is 10.00 V and the measured

of the reference channel is 100.0, the calculated result is 10.00 – 100.0 = –90.00.

value of the reference channel is 5.00 mV, the computed result is 10.00 V – 5.00 mV =

5.00 V.

Configuring the GX/GP

• Square Root

Takes the square root of the input value and converts the unit to obtain the measured

value.

In a differential pressure flowmeter, the output signal is proportional to the square of the

flow rate. Therefore, to measure on a recorder, square rooting is required.

Decimal Place

Set the decimal place of the scale for linear scaling and square rooting.

Span Lower, Scale Upper

Assign values to the results of unit conversion of linear scaling and square rooting.

Note

• The GX/GP converts measured values to values within the range set by the Scale Lower and Scale Upper values with their decimal points removed. For example, if the scale setting is “–5 to 5,” values are converted to values within the span of “10”; if the scale setting is “–5.0 to 5.0,” values are converted to values within a span of “100.” In this case, the resolution of values converted to a span of “10” is lower than those converted to a span of “100.” To prevent the display from becoming coarse, it is recommended that the scale be set so that the span is greater than 100.

• You cannot set the same value to Scale Lower and Scale Upper.

High Limit on Rate-of-Change Alarm and Low Limit on Rate-of-Change Alarm

An alarm is activated if the increasing or decreasing rate-of-change of measured values over a certain interval is greater than or equal to the specified value. The alarm value of an rate-of-change alarm is set using an absolute value. The interval is derived using the following equation and set using the number of samples. Interval = the scan interval × the number of samples

For the number of samples, see page 1-142 in section 1.18.2, “Setting the Interval for

Calculating the Rate-of-Change for Rate-of-Change Alarms”.

Difference High Limit Alarm and Difference Low Limit Alarm

An alarm is activated when the difference in the measured values of two channels is greater or less than or equal to the specified value. This alarm can be specified on measurement channels set to difference calculation.

Note

• If the scales of multiple channels are set to the same position, the scale of the channel assigned first to the group is displayed.

Example: If the order of assignment of a group is 0003.0002.0001, and the scale display

position of all channels is set to 1, the scale of channel 3 is displayed at display position 1.

• Even if some of the scale display positions are skipped, the scale is packed towards display position 1.

Example: Suppose the assignment of channels to a group is 0001.0002.0003, and the display

positions of the scales are set to 1, 3, and 6, respectively. The scales are actually displayed at positions 1, 2, and 3, respectively.

• The scale is divided into 4 to 12 sections by the main scale marks. The section between the main scale marks is divided into 5 or 10 subsections by medium and small scale marks. However, small scale marks are not displayed in the following cases.

• When the resolution of the input range is smaller than the total number of small scale marks.

• When zone display is used.

• When partial expanded display is used (numbers are displayed at the ends of the scale and

at the boundary position).

• The scale values are displayed according to the following rules.

• If the number of scale divisions is 4 to 7 for the vertical trend display, values are displayed at

all main scale marks. If the number of scale divisions is 8 to 12, the values are displayed at every other main scale marks.

• Scale upper and lower limits are displayed at the ends of the scale.

• Scale values are displayed up to three digits excluding the minus sign. However, if the

integer part of values at the ends of the scale is both one digit or the integer part is zero, two digits are displayed.

Example: If the scale is –0.05 to 0.50, the lower limit is “–0.0” and the upper limit is “0.5.”

• If the integer part of either end of the scale is two or three digits, the fractional part is

truncated.

Example: If the scale is 0.1 to 100.0, the lower limit is “0” and the upper limit is “100.”

• If the integer part of either end of the scale is four or more digits, the value is displayed using

a three-digit mantissa and exponent like “×10” or “×102”.

Example: If the scale is 10 to 2000, the lower limit is “1” and the upper limit is “200 × 10”.

• The unit is displayed near the lower limit. If partial expanded display is used, it is displayed near the boundary line. The number of characters that can be displayed is up to six.

The status display section shows the display name, date/time, batch name (when using

the batch function), user name (when using the login function), usage of the internal memory or SD memory card, alarm occurrence, computation status (/MT option), and usage of operation lock or e-mail transmission.

• Data Display Section

The data display section shows the measured data using waveforms, numeric values,

and bar graphs.

Data display section

Group Display

On the trend, digital, and bar graph displays, the data of channels is displayed in groups that are set in advance. Groups are shared among the trend, digital, and bar graph displays. The displayed group can be switched automatically at a specified time interval (5 s to 1 min).

Number of Groups That Can Be Registered GX20/GP20: 50 groups GX10/GP10: 30 groups

Number of Channels That Can Be Assigned to a Group GX20/GP20: Up to 20 GX10/GP10: Up to 10

Update Interval of Measured Values

Values are updated every 0.5 seconds. However, if the scan interval is greater than 1 s, values are updated at the scan interval.

Alarm Indication

Alarms that are set for each channel are checked at all times and are indicated with the symbol representing the alarm type on each display.

Bar Graph

If pre-trigger is specified for event data recording, the GX/GP will start recording pre-trigger data when recording is started and the GX/GP enters the trigger-wait state. “Waiting” appears in the bar graph. At this time, the progress bar turns orange. When the pre-trigger time elapses, the length of the bar is fixed at that point. However, the pre-trigger data is continuously updated in the background until the trigger condition is met. When the trigger condition is met, the bar turns green, and data is recorded after the data in the pre-trigger section.

1.2 Configuring AI Channels (Analog input (including DI) channels)

Note

• Numeric display of analog input channels If a measured value of an analog input channel is over range (see below), the measured

value is indicated as “+Over” or “–Over.” If a burnout is detected on a channel whose burnout detection function is enabled, the word “Burnout” is indicated. For all other cases, a numeric value is displayed.

Over range of analog input channels

• An over range occurs when the measured value of an analog input channel exceeds ±5% of the measurable range. For example, the measurable range when the measurement range is 2 V is –2.000 to 2.000 V. If the measured value exceeds 2.200 V, +over range occurs; if the measured value falls below –2.200 V, –over range occurs.

• For a channel using Linear scaling or Square root, over range occurs if the measured value falls outside the –5% to 105% range of the specified span. You can also change the setting so that over range occurs when the measured value falls outside the –5% to 105% range of the measurable span range. However, +over range occurs if the value excluding the decimal point exceeds 999999 and –over range if it falls below –999999. Setup: See page 1-75 in section 1.7.2, “Setting the Over-range Detection Method”.

When multiple alarms are assigned to one alarm output relay, you can select which condition below will activate the output relay. You can also specify AND operation for internal switches.

• AND: Activated when all assigned alarms are occurring simultaneously

• OR: Activated when any of the specified alarms is occurring

Reflash

When multiple alarms are assigned to one alarm output relay, this function notifies the occurrence of subsequent alarms after the relay is activated by the first alarm. When subsequent alarms occur, the output relay is released temporarily. The duration for which the relays are deactivated can be set to 500 ms, 1 s, or 2 s. Relays set to Reflash will operate using Or and Nonhold settings.

Energize or De-energize Operation

You can select whether the alarm output relay is energized or de-energized when an alarm occurs. If you select de-energize, the alarm output relays will be in the same state when the GX/GP is shut down as they are when an alarm occurs.

Nonhold/Hold

The alarm output relay can be set to operate in the following fashion when the alarm condition is no longer met.

• Turn OFF the relay output (nonhold).

• Hold the relay at ON until the alarm ACK is executed (hold).

Alarm ACK Operation

The alarm acknowledge (alarm ACK) operation releases all alarm indications and relay outputs. For the behavior of alarm indication and alarm output relay when you execute an alarm ACK operation, see below.

• If the number of data points to be averaged has not reached the specified number of samples immediately after computation is started, the average of the available data is computed.

• Computation error data is excluded from the rolling average computation.

• If the computed data exceeds the upper or lower limit, the data is clipped at the upper or lower limit, and the rolling average is computed. The upper and lower limits are “±100000000” ignoring the decimal point. The decimal place is the same as that of the span lower limit.

Explanation

TLOG Computation

TLOG computation determines the sum, maximum, minimum, average, or the difference between the maximum and minimum of a specific channel for each interval determined by a timer.

Computation Data Dropout

A computation data dropout occurs if the computation is not completed within the scan interval.

• The math icon in the status display section turns yellow.

• When a computation data dropout occurs, the computed data of the scan interval in which the dropout occurred is set to the data immediately before the dropout.

• If computation data dropout occurs frequently, reduce the load on the CPU by reducing the number of math channels or setting a longer scan interval.

Numeric Display and Recording

The range of displayed values of computed data is from –9999999 to 99999999 excluding the decimal point. The decimal place corresponds to the decimal place of the lower limit span of the math channel. On the numeric display, values are displayed if the computed result is within the above range regardless of the upper and lower limits of span. The following table indicates special displays.

Display/Recording Computed Data Status

+Over • +Display over: When a computed result exceeds 99999999

–Over • –Display over: When a computed result is less than –9999999

• +Computation over: When a value exceeds approximately 1.79E+308 in the middle of the computation

Special Data Processing

This section explains the handling of special data in TLOG computation, CLOG computation, and reports.

Power Failure Operation (TLOG and Reports)

If a power failure occurs when the report function is enabled or in the middle of the TLOG computation, the report operation and TLOG computation resume when the GX/GP recovers from the power failure. The operation varies depending on whether the GX/GP recovers from the power failure before or after the time to create a report or the TLOG interval timeout.

Time of Recovery Operation

After the time to create the data

Before the time to create the data

The report data is created immediately after the GX/GP recovers. The measured data up to when the power failure occurred is used to create the report. When the time to create the next report data arrives, the data after the recovery is used. The interval timer for TLOG data expires immediately after the GX/GP recovers. After the GX/GP recovers, report data is created at the normal time to create the data. The measured data excluding the power failure period is used to create the report. The interval timer for TLOG data expires after the GX/GP recovers.

Error Data Handling (TLOG, CLOG, and Reports)

If an error occurs in the channel data, the error data is discarded, and the computation continues. If all the data are in error, an error results. The following types of data are considered error data.

• Channels set to skip or Off.

• The measured result on an I/O channel is error (A/D converter failure, etc.).

• I/O channel input is in a burnout condition.

• The computed result on a math channel is error.

Handling of Overflow Data

1 Refers to over range on an I/O channel, computation overflow on a math channel, and over

range on a communication channel.

For TLOG, CLOG, and Reports

When the channel data is overflow data, the GX/GP handles it as follows:

Computation Type Description

Average value or sum value Set the handling to Error, Skip, or Limit.

Maximum, minimum, Maximum – minimum

Error: Sets the computation result to computation error. Skip: Discards overflow data and continues the computation. Limit: Replaces overflow data with the limit value and continues the

computation. Limit value: Span upper or lower limit or the scale upper or lower limit of the channel Set the handling to Over or Skip. Over: Computes by using the overflow data. Skip: Discards overflow data and continues the computation.

1.5.3 Writing Expressions

Common Items

Follow the rules below when writing expressions.

• Use up to 120 characters to write expressions.

• The precedence of computing terms can be specified using parentheses.

• Specify channels in expressions using channel numbers. Example: 0001, 0012, A001, C001

• The “0” in the top digit of I/O channel numbers (0101), math channel numbers (A001), communication channel numbers (C010), constants (K), internal switch numbers (S), and flags (F) can be omitted.

Examples: 101, A1, C10, K1, S1, F1

• The data of the previous scan is used in the computation for its own channel number and channel numbers greater than its own channel number in the expression.

• Write special computations (HOLD, RESET, and CARRY) and conditional expressions at the beginning of expressions.

Order of Precedence in Computations

The order of precedence of computation in expressions is as follows:

Type Computing Element

Function ABS(), SQR(), LOG(), LN(), EXP(), TLOG.MAX(), TLOG.MIN(), TLOG.

Special computation and conditional expression Power ** Logical negation NOT Multiplication and division *, / Addition and subtraction +, – Greater than and less than .GT. (or >), .LT. (or <), .GE. (or >=), .LE. (or <=) Equal and not equal .EQ. (or =), .NE. (or <>) Logical product AND Logical sum and exclusive logical sum

AVE(), TLOG.SUM(), TLOG.P-P(), CLOG.MAX(), CLOG.MIN(), CLOG. AVE(), CLOG.SUM(), CLOG.P-P() PRE, HOLD, RESET, CARRY, [a?b:c]

OR, XOR

Limitations

The following limitations exists in expressions.

Type Limitations

TLOG Computation A computing element cannot be written inside the parentheses.

CLOG computation The number of channels that can be written in the parentheses is up to 30

PRE A computing element cannot be written inside the parentheses. HOLD(a):b Can only be written at the beginning of an expression.

RESET(a):b Can only be written at the beginning of an expression.

CARRY(a):b Can only be written at the beginning of an expression.

Only one TLOG computation can be specified in a single expression.

channels. A computing element cannot be written inside the parentheses. Only one CLOG computation can be specified in a single expression.

Only one HOLD computation can be specified in a single expression.

Only one RESET computation can be specified in a single expression.

Only one CARRY computation can be specified in a single expression. Only TLOG.SUM can be written in b. RESET, CARRY, or HOLD cannot be written to a, b, or c. Other computing elements cannot be combined (example: [a?b:c]+0001). However, conditional equations can be specified for a, b, and c.

Explanation

2ch Mode and 10ch Mode (AI modules)

In 10ch mode, measurement is possible on CH1 to CH10. In 2ch mode, measurement is possible only on CH1 and CH2. (CH3 to CH10 are fixed to Skip.) In 10ch mode, when the scan interval is set to 100 ms or 200 ms, the A/D integration time is fixed at 1.67 ms. This prevents power frequency noise from being eliminated, causing measured values to wobble (especially for temperature). In 2ch mode, when the scan interval is 100 ms or 200 ms, the A/D integration time is

16.67 ms or 20 ms. This allows power frequency noise to be eliminated. Note that the selectable A/D integration times vary depending on the 2ch/10ch mode and scan interval settings.

Normal and Remote (DI modules)

Specify Remote to use the DI module as a remote control input. When there are multiple DI modules, only one of them can be set to Remote. For normal DI input, specify Normal.

When using Event action, set to Remote.

• If you are using the 24 VDC power supply on models with the 24 VDC/AC power supply (/P1 option), the A/D integration time is fixed to 20 ms

(50 Hz). 50Hz Sets the integration time to 20 ms. 60Hz Sets the integration time to 16.67 ms. Common Sets the integration time to 16.67ms, 36.67 ms or 100 ms.

Explanation

Integration Time of the A/D Converter

The GX/GP uses an A/D converter to convert sampled analog signals to digital signals. By setting the integration time of the A/D converter to match the time period corresponding to one cycle of the power supply or an integer multiple of one cycle, the power supply frequency noise can be effectively eliminated. Common (36.67 ms/100 ms) can specified to effectively eliminate power supply frequency noise for both 50 Hz and 60 Hz.

Waveform Updating

On the screen, 30 dots along the time axis is represented by a unit called division. The displayed waveform is updated at an interval corresponding to one dot. This interval is determined by the specified recording interval (which corresponds to one division referred to as the trend interval). The table below shows the relationship between the trend interval and the speed of movement of waveforms on the screen.
