SLC Status File B-7
S:1/6 Status Forces Installed Bit
This bit is set by the processor if you have installed forces in a
ladder program. The forces may or may not be enabled.
Otherwise the bit remains cleared. The processor Forced I/O
LED flashes when forces are installed, but not enabled.
•••••
S:1/7 Status Communications Active Bit (Channel 1)
This bit is set by the processor when at least one other node is
present on the network attached to channel 1. Otherwise, the
bit remains cleared. When the node is active, it is a recognized
participant in a DH-485 or DH+ token-passing network. For
Ethernet communications, this bit is only an indication that the
Ethernet daughter board is functioning properly, not
necessarily that there are any other active Ethernet nodes, or
that channel 1 is connected to an Ethernet network.

S:1/8 Dynamic
Config
Fault Override at Powerup Bit
When set, this bit causes the processor to clear the Major
Error Halted bit S:1/13 and Minor error bits S:5/0 to S:5/7 on
power up; if the processor had previously been in the REM Run
mode and had faulted. The processor then attempts to enter
the REM Run mode. When this bit remains cleared (default
value), the processor remains in a major fault state at power
up. To program this feature, set this bit using the Data Monitor
function.
•••••
S:1/9 Dynamic
Config
Startup Protection Fault Bit
When this bit is set and power is cycled while the processor is
in the REM Run mode, the processor executes your fault
routine prior to the execution of the first scan of your program.
You then have the option of clearing the Major Error Halted bit
S:1/13 to resume operation in the REM Run mode. If your fault
routine does not reset bit S:1/13, the fault mode results.
To program this feature, use the Data Monitor function, then
program your fault routine logic accordingly. When executing
the startup protection fault routine, S:6 (major error fault code)
will contain the value 0016H.
