3000 MISSING SOR The rung does not begin
with a start of rung
instruction. Add a start of rung instruction to
the beginning of the rung using
the
NEW RUNG key.
3001 INVALID INPUT The first input instruction
on the rung is not a load
instruction (e.g., LD, LDI,
LD EQU). Change the input instruction
immediately after the Start of
Rung instruction to a load
instruction.
3002 MISSING OUTPUT The rung does not end
with an output
instruction. Add the appropriate output
instruction to the end of the
rung.
3003 INVALID RUNG An instruction or
instruction block needs
an ANB or ORB to
properly join it with the
previous input logic on
the rung. Check that all instructions or
instruction blocks have been
properly joined to the previous
input logic on the rung with an
ANB or ORB.
3004 INVALID RUNG An MPP is missing from
the rung. Add an MPP at the proper
location.
3005 INVALID ORB An ORB instruction is
illegally positioned on the
rung. Move the ORB to the correct
location on the rung or remove
it if the application does not
require it.
3006 INVALID ANB An ANB instruction is
illegally positioned on the
rung. Move the ANB to the correct
location on the rung or remove
it if the application does not
require it.
3007 INVALID ORB, OR The position of an OR or
ORB instruction after an
MPS, MRD, or MPP
instruction has created
an illegal rung. Review and rewrite the
instruction list logic. Two rungs
may be required to implement
the desired functionality.
