9-166 Programming Techniques Program File 2 0000 0001 0002 Copy the System Status Word (SSW) and the Module Status Word (MSW) from the BSN module to internal storage words in the SLC processor every program scan. Bits 6 and 7 of the SSW word indicate whether this processor is Primary or Secondary at any given time. Bits 6 and 14 of the MSW word indicate whether the local or remote system is in the Primary or secondary Mode respectively. Virtual SSW and MSW words/bits are used to minimize M-file transfers, thereby minimizes their effects on the program scan time.

Program File 3 0000 0001 0002 0003 0004 Programming Techniques 9-167 The following rungs are meant to be executed only when this processor/BSN is in the Backup Mode. When it is acting as the Bac kup Processor, this rung copies the DTSW (Data Table Status Word) to an internal storage word within the SLC processor, B3:3 in this example. Virtual & Actual DTSW Words MOV Move Source M1:1.3410 ?< Dest B3:3 0000000000000000< This rung copies the "new" Data Block #1 data from the secondary BSN to a file within the secondary processor. When the COPy is complete, the DTHW (Data Table handshake Word) bit for Data Block #1 (B3:4/0 = M0:1.3411/0) must be set to inform the secondary BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #1.

When the COPy is complete, the DTHW (Data Table handshake Word) bit for Data Block #2 (B3:4/1 = M0:1.3411/1) must be set to inform the secondary BSN that the secondary processor has received the latest Data Block and is now ready for the next block of data via Data Block #2.
