Description

• This program illustrates how to configure one line of port translation in the Store and Forward translation table for the 16-bit family of SCADAPack controllers.
  Note: Store and Forward capability on 32-bit (SCADAPack 32 and 32P) controllers may be configured using the "Controller | Store and Forward" command dialog.

• The Store and Forward table is configured with one line of translation as follows: Any Modbus messages received on com1 and addressed for station 3 are translated to station 3 and sent out of com2.

• The Register Editor dialog has been pre-configured to display all pertinent registers used in this program.

• The controller type has been pre-selected as SCADAPack.

• The Register Assignment has been pre-configured with the DIAG Serial Port Protocol Status, CNFG Protocol Settings Method 1 and CNFG Store and Forward modules.

• The Store and Forward capability for each serial port can be enabled either from the "Controller | Serial Port" dialog or by hard coding it into the actual ladder code using the "CNFG Protocol Settings Method 1" module. This example uses the latter technique.

• Refer to the "Ladder Logic Function Reference | Ladder Logic Function Reference | Ladder Logic Functions" section of the "TelePACE User and Reference Manual" for information on the PUTU function.
