Code Description
21 I/O memory address
out-of-range
29 Reception error for
external device
30 Response timeout
31 Controller unit number
duplicated
70 Illegal combination of
function blocks
71 Inappropriate
parameter
74
Explanation
An address out of the I/O
memory address range
has been specified on the
CPU Unit Terminal,
Expanded CPU Unit
Terminal, Node Terminals
and Field Terminal blocks.
A communications frame
error was generated by the
data received from an
ES100X Controller for an
ES100X Controller
Terminal (Block Model
045). (An FCS check error
or frame error occurred 3
times in a row.
A response was not
returned after sending data
to the Controller for a
ES100X Controller
Terminal (Block Model
045). (Response was not
returned for 5 s 3 times.)
The unit number set in
ITEM 006 for a ES100X
Controller Terminal (Block
Model 045) is the same as
another ES100X Controller
Terminal. (A response
timeout will occur if the unit
number does not exist.)
The function block on the
primary loop side is not
basic PID or advanced PID
when bumpless
processing between
primary/secondary loops
was specified in basic PID
or advanced PID.
a) When restricted conditions
are applied across two
ITEMs:
(example: when the unit
pulse output is equal to or
greater than the operation
cycle when there is unit
pulse output in run time ac-
cumulation)
b) An attempt has been made
to write out-of-range data at
the ITEM Setting block.3.
Operation at Error
Operation of the function
block in question is
stopped.
Communications will be
stopped with the specified
ES100X and tried with
another ES100X.
Communications will be
stopped with the specified
ES100X and tried with
another ES100X.
Communications will be
stopped with the ES100X
Controllers
Running of the function
block in question is
stopped.
a) The function block in ques-
tion is not executed.
b) Data cannot be written.
Section 3-14
Remedy
On the CPU Unit Terminal
and Expanded CPU Unit
Terminal blocks, check the
leading address, and on
field terminals check the
setting of the CIO (channel
I/O) Area number setting.
In the case of Node
Terminals, check the
setting of the "leading
address of the memory for
the node terminals"
specified by System
Common block ITEM043.
Check the communications
path and the
communications settings
(7 data bits, even parity,
and 2 stop bits).
Check the communications
path, the communications
settings (7 data bits, even
parity, and 2 stop bits), and
other required settings in
the ES100X (parameter
setting mode, unit number,
etc.).
Change the unit number
settings (ITEM 006)so that
each is used only once.
Check the function block
model number on the
primary loop side.
Check the settings of the
ITEMs.
