15.1.4 Writing Data to RAM or Flash

Folder data is stored from the programmer to the EZ Program Store device in the same
way data is stored to Flash memory. Writing to either Flash or to the EZ Program Store
device always writes all folder data (regardless of what types are selected). Data stored to
the EZ Program Store device is verified in the same manner as data stored in Flash
memory is verified. Data can also be read from the device in the same manner as reading
from Flash.
The EZ Program Store device can be used to update data in a PLC's RAM memory only,
or in both RAM and Flash memory. In the configuration data stored to the EZ Program
Store device, be sure to specify which type of memory should be updated. Select RAM
only to update only RAM memory in the target PLC. Select RAM & FLASH to update
both.

Programmer
Programmer
To read/write or verify some or all of the data, follow these steps:
1. Plug the EZ Program Store device into port 2 of the VersaMax PLC CPU. The
device's LED turns green after about 2 seconds. The delay allows time for proper
seating of the device.
2. If the PLC is in Run mode when the EZ Program Store device is connected, the Run
LED on the PLC blinks at a 1 Hz rate.
