Setting initial device values
This section describes the settings of initial device values.
Setting procedure
The procedure for using initial device values is as follows.
1. First, the user must create an initial device value file. To set initial values to a global device, create an initial device value
file (with any name) which sets these initial values, and specify the range of the values.
2. On the device memory, set up initial device value data within the range specified in the initial device value file.

3. In the "Device Memory Register Diversion", select the device memory which was set up in Step 2. Setting "Device
Memory Register Diversion" enables data set up on the device memory to be used as initial device values for the device
which is specified in the initial device value file.

powered off and on, reset, or the status changes from STOP to RUN.
