Processor Mode/Status
Read only. Bits 0 – 4 function as follows:
0 0000 = (0) Download in process
0 0001 = (1) Program mode (the fault mode exists when bit
S:1/13 is set along with mode 0 0001)
0 0011 = (3) Suspend Idle (operation halted by SUS instruction
execution)
0 0110 = (6) Run mode
0 0111 = (7) Test continuous mode
0 1000 = (8) Test single scan mode
• •
0 1001 = (9) Test single step (step until)
All other values for bits 0–4 are reserved or unallocated.
•
S:1/5 Forces Enabled Bit
Read only. This bit is set by the processor if you have enabled forces
in a ladder program. Otherwise the bit remains cleared. The
processor “Forced I/O” LED is on continuously when forces are
enabled.
• •
S:1/6 Forces Installed Bit
Read only. 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 Communications Active Bit
Read only. This bit is set by the processor when at least one other
node is present on the DH–485 link. Otherwise the bit remains
cleared. When a device is active, it is a recognized participant in a
DH–485 token-passing network.
• •
S:1/8 Fault Override at Powerup Bit
Read/write. When you set this bit, it 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
powerup, if the processor had previously been in the Run mode and
had faulted. The processor then attempts to enter the 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 EDT_DAT function.
