and
S:8
Status Suspend Code/Suspend File
When a non-zero value appears in S:7, it indicates that the
SUS instruction identified by this value has been evaluated
as true, and the Suspend Idle mode is in effect. This
pinpoints the conditions in the application that caused the
Suspend Idle mode. This value is not cleared by the
processor.
Word S:8 contains the program file number in which a true
SUS instruction is located. This value is not cleared by the
processor.
Use the SUS instruction with startup troubleshooting, or as
runtime diagnostics for detection of system errors.
Application example: You believe that limit switches
connected to I:1/0 and I:1/1 cannot be energized at the
same time, yet your application program acts as if they can
be. To determine if you have a limit switch problem or a
ladder logic problem, add the following rung to your
program:
If your program enters the SUS Idle mode for code 1 when
you run the program, you have a limit switch control
problem; if the SUS Idle mode for code 1 does not occur, you
have a ladder logic problem.
•••••
S:9 Status Ethernet Daughter Board Firmware Series (Channel 1
- SLC 5/05 processors)
A value of 1 corresponds to Series 1, for example.
•
S:10 Status Ethernet Daughter Board Firmware Revision (Channel
1 - SLC 5/05 processors)
A value of 12 corresponds to Revision 12, for example.
•
S:9
and
S:10
Status Active Nodes (Channel 1-SLC 5/03 processors)
These two words are bit mapped to represent the 32
possible nodes on a DH-485 link. S:9/0 through S:10/15
represent node addresses 0-31. These bits are set by the
processor when a node exists on the DH-485 link that your
processor is connected to. The bits are cleared when a node
is not present on the link.
