Application Storage
The IEC 61131-3 application(s) loaded into the SCADAPack E RTU is stored in a non-volatile file system
directory on the RTU called "C:\ISaGRAF5". When power is restored after an outage, each stored
application is validated by the RTU and a separate copy is made in volatile RAM for execution.
If both copies are not valid, the IEC 61131-3 target waits for a new application to be loaded and the
Application Halted system binary point for that Resource is activated (RTU system binary point 50100 or
50101).
Variables, other than those specified in the resource as retained variables, are stored in volatile (nonsaved) memory. The IEC 61131-3 target initializes their values when the application restarts.
The IEC 61131-3 applications are stored in the RTU file system in files called:
"ISPxxx01" is the resource's compiled TIC code.
"ISPxxx03" is the resource's configuration file.
"ISPffe0d" is the Network configuration file (shared between resources)
"IDSxxx01" is the resource's Symbol Table information.
"IDSxxx03" is the resource's Embedded Zip Source data (if configured).
Where: "xxx" is the resource number, eg. "001".
The SCADAPack Workbench supports resource numbers "1" and "2" corresponding to the two
SCADAPack E IEC 61131-3 target Resources.
