Remedy
calculated.
Two or more S1 to S3 select
switches are set to 1 (ON) at the
same time in the 3-output Selector
block (Block Model 163) or 3-input
Selector block (Block Model 164).
The output value that was
active before the error
occurred is held.
Re-program the Step Ladder
Program block so that S1 to
S3 select switches are set to
1 (ON) independent of each
other.
There is a syntax error in Arithmetic
Operation (Block Model 126), the
THEN or ELSE expression is not
defined, or the output reverse
scaling limits are not set.
Execution of the Arithmetic
Operation block will be
stopped.
Check the contents of the
conditional statement and
calculation expressions an
check the settings of the
output reverse scaling limits.
19
Inappropriate
operation
There are syntax errors in the
membership functions or rules for
the Fuzzy Logic block (Block Model
016) making execution impossible.
a)
A value does not have one sign
character and 5 or fewer
numeric characters (e.g., when
a + sign is included).
b)
Values are not separated by
colons.
c)
The values that have been set
are insufficient.
d)
There are more than three
critical points in a membership
functions.
e)
Critical points in membership
functions do not rise to the right.
f)
Membership functions are not
set for labels specified in rules
(NL, NS, ZR, PS, PL).
Operation of the Fuzzy
Logic block will stop.
Check the membership
functions and rules.
The ITEM number where the
problem occured is given in
ITEM 006 (Operation Error
Details).

Download
terminal data
exchange error
Data exchange with the CPU Unit is
not being executed correctly on the
CPU Unit Terminal, Expanded CPU
Unit Terminal, Node Terminals and
Field Terminal blocks.
The data of the function
block in question is not
updated.
If a malfunction has occurred
on the CPU Unit, follow the
remedy for that error. If the
CPU Unit is normal, turn ON
the power supply again.
21
I/O memory
address out-of-
range
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.
Operation of the function
block in question is
stopped.
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.
29
Reception error
for external
device
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 occured 3 times in a
row.
Communications will be
stopped with the specified
ES100X and tried with
another ES100X.
Check the communications
path and the communications
settings (7 data bits, even
parity, and 2 stop bits).
30
Response
timeout
A response was not returned after
sended data to the Controller for a
ES100X Controller Terminal (Block
Model 045). (Reponse was not
returned for 5 s 3 times.)
Communications will be
stopped with the specified
ES100X and tried with
another ES100X.
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.).
