EZ Program Store Device IC200ACC003





It writes over accessible program files, configuration, and data in the target PLC when the Store device of EZ Program revises a PLC. Consequently, it is significant to be convinced that the information located on the Store device of EZ Program is whole for appropriate operation of the PLC system. For instance, if the Store device of EZ Program includes an application program, but in place of an adapted configuration of hardware it contains the default configuration of PLC, the revise will overwrite any accessible data configuration in a PLC being revised. If that occurs, the PLC system modules will then utilize their configuration default, which may reason unanticipated operation.

Matching Protection of OEM
If the PLCs that will be changed by the Store device of EZ Program are secured by a key password of OEM, be sure the same key password of OEM is current in the configuration saved to the Store device of EZ Program, otherwise no renew will be possible. If the PLCs being updated had no key password of OEM allocated, the Store device of EZ Program have to also not have a key password of OEM. The device does not utilize other system passwords.

Changing the Timeouts Configuration
Writing and reading hardware configurations, large programs, and tables reference to or from the Store device of EZ Program may get 30 secs or more to finish. To prevent potential disconnect errors or read or write faults, regulate the demand timeouts in the design to 30 - 63 secs.

Writing Data to Flash or RAM
Folder data is saved from the programmer to the Store device of EZ Program in the similar way data is saved to memory Flash. Writing to the EZ Program Store device or to either Flash always writes all data folder not considering of what types are chosen. Data saved to the Store device of EZ Program is established in the similar manner as data saved in Flash memory is confirmed. Data can also be interpreted from the tool in the similar manner as interpreting from Flash. The Store device of EZ Program can be utilized to revise data in a RAM memory of PLC only, or in both Flash memory and RAM. In the design data saved to the Store device of EZ Program, be sure to identify which memory type should be updated. Choose RAM only to revise only memory of RAM in the target PLC. Choose RAM & FLASH to renew both.
