B-58 SLC Status File
S:61 Status Processor Series
Indicates the processor series. For example, the value of 0
indicates series A and the value of 1 indicates series B.
S:62 Status Processor Revision
Indicates the processor revision. For example, the value of 1
indicates REV1 and the value of 2 indicates REV2.
•••
S:63 Status User Program Type
Indicates the programming device that created the user
program.
•••
S:64 Status User Program Functionality Index
Indicates the level of functionality contained in a given
program type.
•••
S:65 Status User RAM Size
Applies to SLC 5/03 (OS302), SLC 5/04 (OS401), and SLC
5/05 processors.
Indicates the size of NVRAM in instruction words. For
example, the value 64 equals 64K instruction words of
NVRAM.
•••
S:66 Status Flash EEPROM Size
Indicates the size of operating system memory in 16 bit K
words. For example, the value of 128 equals 128K words of
memory.

S:67 to S:82 Status Channel 0 Active Node Table
When channel 0 is configured for DF1 Half-duplex Master or
DH-485, these 16 words are bit mapped to represent status
of the nodes on the network. For the DH-485 network only
32 possible nodes are allowed. For the DF1 Half-duplex
Master network 255 nodes are allowed. Bit S:67/0
represents node 0, bit S:82/14 represents node 254, and bit
S:82/15 is not used since address 255 is reserved for
broadcasts.
DF1 Half-duplex Master configured for either of the two
standard polling modes has these bits set by the processor
when a node is polled and it responds to the master poll. A
node’s bit is cleared if no response is received after a
master poll.
In DH-485 configuration, these bits are set by the processor
when a node exists on the DH-485 link that your processor
is connected to. These bits are cleared when a node is not
present on the link.
