Explanation
With the Segment Program 3
block (Block Model 158),
when the program pattern
transfer order (CPU Unit to
LCB) is executed, the maxi-
mum numbers of steps and
banks used in the program
pattern data in the CPU Unit
do not match the Segment
Program 3 block (Block
Model 158) maximum num-
ber of steps used (ITEM 038)
and the maximum number of
banks used (ITEM 043) set-
tings.
With the Segment Program 3
block (Block Model 158),
some program pattern data
at the CPU Unit is set out of
range.
With the Segment Program 3
block (Block Model 158),
when program pattern data
was changed by downloading
the ITEM, the time width for
the step before the one being
executed was changed to
0.0.
Power was interrupted or
LCB operation was stopped
during execution of a pro-
gram pattern transfer order
(CPU Unit to LCB) with a
Segment Program 3 block
(Block Model 158).
Power was interrupted or
LCB operation was stopped
during execution of a pro-
gram pattern transfer order
(LCB to CPU Unit) with a
Segment Program 3 block
(Block Model 158).
The total of the time widths in
a Segment Program 3 block
(Block Model 158) exceeded
the maximum value.
Maximum value =
429496729.5 s (approx.
13.61 yr)
Operation at error
Program pattern data is not
transferred (CPU Unit to
LCB).
In ITEM 024 (error detection
address), the parameter off-
set address where the CPU
Unit to LCB transfer failed is
indicated (only when an exe-
cution error occurs).
Program pattern data is not
transferred (CPU Unit to
LCB).
In ITEM 024 (error detection
address), the parameter off-
set address where the CPU
Unit to LCB transfer failed is
indicated (only when an exe-
cution error occurs).
The run/stop command
(ITEM 013) turns OFF. The
program outputs will be the
values set for the program
outputs at reset.
The transfer stops. The pro-
gram pattern transfer order
(CPU Unit to LCB) (ITEM
031) stays ON.
The transfer stops. The pro-
gram pattern data transfer
command (LCB to CPU Unit)
(ITEM 030) stays ON.
The run/stop command will
turn OFF if it is ON.
Section 7-1
Remedy
Turn OFF the program pat-
tern transfer order (ITEM
031), match the maximum
number of steps used and
the maximum number of
banks used at the CPU Unit
with the values in the Seg-
ment Program 3, and then
again turn ON the program
pattern transfer order (CPU
Unit to LCB).
Turn OFF the program pat-
tern transfer order (ITEM
031), make sure all settings
are within the specified
ranges, and then again turn
ON the program pattern
transfer order (CPU Unit to
LCB).
When the run/stop com-
mand is turned ON, opera-
tion starts with the step with
time width 0.0 as the final
step, so reset the step time
width before turning ON the
run/stop command.
Either turn the program pat-
tern transfer order (CPU Unit
to LCB) OFF and then back
ON, or clear the error by set-
ting the execution error dis-
play/clear (ITEM 003) of
Segment Program 3 (Block
Model 158) to 0.
Either turn the program pat-
tern data transfer command
(LCB to CPU Unit) OFF and
then back ON, or clear the
error by setting the execution
error display/clear (ITEM
003) of Segment Program 3
(Block Model 158) to 0.
Change the time widths so
that the maximum total value
is not exceeded.
