The Scratchpad String Points fields are ‘grayed out’ and unavailable for use if any of the outstation’s serial ports are configured to route data using the X.29 communication driver interface (see Specify the X.29/TC Comms Properties).
Use the fields within the Scratchpad String Points section of the SCADAPack tab to specify up to eight arbitrary strings that are to be stored in the SCADAPack E outstation.
The Scratchpad String Points can be accessed in an ISaGRAF application running in the outstation. See the SCADAPack E product documentation for further details.
