Chapter 8 Starting Up
Click the Scanlist tag and move the device from Available Devices to Scanlist.
Highlight each device moved to Scanlist and click
[Edit I/O Parameters]. Set the I/O communication type and I/O data size.
Check "Automap on Add" and move the devices to Scanlist in order to automatically map each device to the
WL area.
If it is desired to map devices individually, map each device according to the steps in "Mapping of I/O data
to WL" described later, without checking "Automap on Add."
2. Set the I/O communication type and I/O data size
Make sure to select an I/O communication type supported by the device.
I/O data size must be set up in the byte unit. ( Refer to the Table 6.2 )
The default I/O data size of the EH-IOCD is 8 bytes for both input and output.
Make sure to set the same size as for the mounted module.
It is shown on the following page how to calculate the I/O data size.
For devices whose default I/O communication type and data size are defined in the EDS file, it is not necessary to
change the settings as far as they are in use.
