Introduction

Thank you for purchasing the SMARTDAC+ Series GX10/GX20/GP10/GP20/GM10 (hereafter referred to as the recorder, GX, GP, or GM). This manual explains the WT communication function of the GX, GP, and GM.

Although the display of GX20 is used in this manual, GX10/GP10/GP20 can be operated similarly. Moreover, for the GM10, the same content can be displayed on a Web browser.

In this manual, the GX20, GP20, and GM10 standard type and large memory type are distinguished using the following notations.

• Standard type: GX20-1/GP20-1/GM10-1

• Large memory type: GX20-2/GP20-2/GM10-2 For details on the features of the recorder and how to use it, read this manual together with the following user’s manuals.

Using the WT Communication (/E2 option)

Overview

The WT communication function collects values measured and computed on WT power meters and analyzers made by Yokogawa Meters & Instruments Corporation using Ethernet communication into the recorder. The collected data can be assigned to communication channels (/MC option) and displayed and recorded simultaneously with the measured data of the recorder.

Procedure up to Data Collection

Connect WTs to the recorder using Ethernet cables.

Configure the WT connection client function.

• Basic settings Set the WT connection client function to On. Set the data collection interval and recovery action.

• Connection destination server settings Set the server names (IP address or host name) and the model names of the serv-

ers (WTs) that the Recorder is to connect to.

• Assignment of collection data to communication channels Set the WTs that data is to be collected from, collected items, and exponential scal-

ing of the data read from the WT.

Configure communication channels, recording settings, display settings, and so on.

• Communication channel settings Set the span, unit, etc.

• Recording settings Assign communication channels to recording channels.

• Display settings Assign communication channels to display groups.

• Other settings Set the watchdog timer.

Note

If the On/Off setting is set to Off, data collection from the WT will be stopped. In this situation, communication data will not be updated and will hold the previous value. For the detailed operation, see “Watchdog Timer” under “Other Settings” in page 13 ,

“Configuring Communication Channels, Recording Settings, and Display Settings”.

Server No

Set the connection destination server number of the server (WT) that data is to be collected from.

Data group name

Set the data group name of measurement function to collect.

Refer to “Data group name and data name”.

Note

Data group names can be specified regardless of the number of WT elements to be connected or options. If data is read from elements or options that are not installed in the target WT, it will become NaN (Not a Number) data. If the data group name is set to OFF, communication data will not be updated and will hold the previous value.

For the detailed operation, see “Watchdog Timer” under “Other Settings” in page 13 , “Configuring

Communication Channels, Recording Settings, and Display Settings”.

Data name

Set the data name of measurement function to collect.

Refer to “Data group name and data name”.

Exponential scaling

Set the exponent used to exponentially scale the data read from the WT using base 10. For example, if the measured value of the WT is 123.45 kW and you specify -3, the data will be scaled by 10-3 to derive data in unit of kW.

Communication channel

Set the communication channel to assign the data collected from the WT to.

Valid Data Groups Based on the WT Specifications

Data group names can be specified regardless of the number of WT elements to be connected or options. If data is read from elements or options that are not installed in the target WT, it will become NaN (Not a Number) data. The following table shows the valid group names depending on the number of WT elements and option specifications.

Collected Data

• Data is collected from all specified WTs. WT data that cannot keep up with the read cycle will take on the previous value. In this

situation, a data dropout icon appears in the status display. ( See page 14 , “Monitoring the WT Collection Status”)

• If data cannot be collected from a WT, the previous value will be held. For the detailed operation, see “Watchdog Timer” under “Other Settings” in page 13 , “Configuring Communication Channels, Recording Settings, and Display Settings”.

• If multiple functions are assigned to a single communication channel, the function with the largest assignment number takes precedence.

In addition, if data input through another communication protocol, such as Modbus client

or master, uses the same channel, the channel will take on values that are retrieved according to the communication protocol’s data update interval.

Do not assign input from other communication protocols, such as Modbus communication

or general communication, to communication channels that WT data is assigned to.

Configuring Communication Channels, Recording Settings, and Display Settings

Communication channel settings

Set the communication channel to assign the data collected from the WT to.

See section 1.20, “Setting Communication Channels (/MC option),” in the User’s Manual (IM 04L51B01-01EN) or section 2.21, “Setting Communication Channels (/MC option),” in the User’s Manual (IM 04L55B01-01EN).

Recording settings

Assign communication channels to recording channels.

For details on setting recording channels, see section 1.12.2, “Setting Recording Channels,” in the User’s Manual (IM 04L51B01-01EN) or section 2.13.2, “Setting Recording Channels,” in the User’s Manual (IM 04L55B01-01EN).

Display settings

Assign communication channels to display groups.

See section 1.10.2, “Setting Display Groups,” in the User’s Manual (IM 04L51B01-01EN) or section 2.11.2, “Setting Display Groups,” in the User’s Manual (IM 04L55B01-01EN).

Other settings

Watchdog timer

The watchdog timer function replaces values with their preset values or last values and when values are not updated within the specified duration (timer) . Set the watchdog timer so that communication interruptions caused by communication errors can be detected.

Status Output

On a GX/GP, notification can be sent when there is a WT communication error due to a communication error with the status relay (/FL option).

See section 1.23.6, “Setting the FAIL Relay and Instrument Information Output (/FL option),” in the User’s Manual (IM 04L51B01-01EN) .

On a GM, you can use the event action function to send a notification when there is a WT communication error.

See section 2.20, “Configuring the Event Action Function,” in the User’s Manual (IM 04L55B01-01EN).
