System Monitor Screens Section 4-17
19 Inappropriate operation 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 Lad-
der Program block so that
S1 to S3 select switches
are set to 1 (ON) indepen-
dent of each other.
20 Download terminal
data exchange error Data exchange with the CPU
Unit is not being executed
correctly on the CPU Unit Ter-
minal, 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 nor-
mal, 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 Ter-
minals 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 Termi-
nals, check the setting of
the “leading address of the
memory for the node termi-
nals” 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
occurred 3 times in a row. Communications will be
stopped with the specified
ES100X and tried with
another ES100X. Check the communications
path and the communica-
tions settings (7 data bits,
even parity, and 2 stop bits).
30 Response timeout A response was not returned
after sending data to the Con-
troller for a ES100X Control-
ler Terminal (Block Model
045). (Response 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.).
31 Controller unit number
duplicated 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.) Communications will be
stopped with the ES100X
Controllers Change the unit number
settings (ITEM 006)so that
each is used only once.
70 Illegal combination of
function blocks The function block on the pri-
mary loop side is not basic
PID or advanced PID when
bumpless processing
between primary/secondary
loops was specified in basic
PID or advanced PID. Running of the function
block in question is
stopped. Check the function block
model number on the pri-
mary loop side.
