Exchanging Data with the CPU Unit Section 3-3
This function can be set when the following settings are selected.
A/D (allocation size): Contact
R/W: Wr (LCB →) (data written from the Loop Controller to the CPU Unit)
User Link Table Errors A user link table error will occur if the user link table is executed with the fol-
lowing settings.
1,2,3... 1. The function block address and ITEM number set for writing to the ITEM
do not exist.
2. An EM bank number that does not exist in the CPU Unit has been set as
the memory type. The user link table in which the user link table error oc-
curred will not execute. The entry number for the user link table in which
the error occurred is displayed in ITEM 095 of the System Common Block.
If multiple user link table errors occur, the errors will be displayed according to
the following priority.
1,2,3... 1. If an Rd (→LCB) and Wr (LCB→) error occur, the entry number of the Rd
(→LCB).
2. If multiple Rd (→LCB) errors occur, the entry number for the user link table
that was downloaded first will be displayed.
3. If multiple Wr (LCB→) errors occur, the entry number for the user link table
that was downloaded last will be displayed.
Note (1) The Loop Controller can read and write data in the CPU Unit's I/O mem-
ory using the User Link Table (independent of the CPU Unit's user pro-
gram.) To avoid conflicts, do not write to the same I/O memory address
from both the Loop Controller and CPU Unit.
(2) If the user link table cannot be executed for the following reasons, the
user link table entry number will be displayed in ITEM 095 (user link table
error) of the System Common Block.
• The ITEM does not exist at the connection destination.
• The ITEM is unsuitable.
• The CPU Unit I/O memory area does not exist.
MV Tight Shut
Function
(LCB01/03/05 Ver. 3.0
or Later)
Tight shut outputs can be made to the CPU Unit I/O memory area from field
terminals (analog output terminals) or user link tables. If the output value is
0% or lower, the value set as the lower limit will be output. If the output value
is 100% or higher, the value set as the upper limit will be output. With this
