Setting the wireless device (YTMX580) CF/DD file
Double-click the Device Tag cell of the added device. A
dialog box shown in figure 19 appears. Click Load CF/
DD to set the wireless device (YTMX580) CF/DD file.
By default, the YTMX580 CF/DD file is in C:\
Program Files\Yokogawa\DTM\DTMev\EV\
ISA100\00594543\1802.

When you set the file, the Sampling data tab is added as shown
in figure 20. Device Role becomes editable. Change it to IO
.

Setting the Publish Period
Publish is a function that the wireless device
(YTMX580) uses to periodically send PV and device
status (DIAG_STATUS) and the like to the built-in GW.
The YTMX580 publish settings are specified on the
Sampling data tab shown in figure 21.
Figure 21 shows the settings for sending the PV
and DIAG_STATUS of parameter AI_01 to AI_08 at
an update period of 5 seconds. After changing the
settings, click Apply.

Setting the Modbus registers
Map the PV sent from the wireless device (YTMX580)
to the built-in GW registers. By doing this, you will be
able to read the data from the GX20W using Modbus
communication.

On the Modbus Configuration tab of figure 18, map the
parameters by dropping them to the Input Registers
number positions.
Figure 22 shows the DIAG_STATUS and PV of the
wireless device (YTMX580) mapped to the built-in GW
registers.
When you are finished, click Apply Changes (figure 23)
to update the settings.
