*2 When entering a check in the box of [Use Multiple Read/Write Command] in the [Individual Device Settings],
it corresponds to the device monitor. Other classes and cases where a check has not been entered do not
correspond to the device monitor.
*3 The Display is 32 bit data, but the External Device is 16 bit data. Therefore, only low 16 bit data is valid. In the
case that data is read from the External Device, data except for low 16 bits becomes zero.
*4 If multiple points writing the S device, the P device, the BP device and the EX device, please use the memcpy
command.
The points can be specified are as follows.
S device: Multiples of 16 (Example: 16 points, 32 points, 48 points, etc.)
P device: 13 points
BP device: 9 points
EX device: 9 points
*5 The Multiple Read/Write attribute of the External Device is fixed to zero. To specify with the Display, set to
"1".
*6 Can be used for the External Devices except for DX200 series.
*7 Can be used for DX200 series only.
*8 When the [Use Multiple Read/Write Command] is selected, set the same attribute as the Single Read/Write of
the same device. 
Refer to the External Device Manual for the content of the attribute.
• When using a class that is not supported by the driver, no error occurs with the GP-Pro EX. If
project transfer to the Display and restart are conducted, an improper device error occurs.
