Data Link Area
Section 4-4
Note The built-in analog outputs will operate as follows when the operating mode is
switched between RUN or MONITOR mode and PROGRAM mode:
Note Control of the built-in analog outputs will temporarily stop when Memory Cas-
sette data is being transferred or verified. Therefore, if the operating mode is
switched between PROGRAM and RUN or MONITOR mode when the built-in
analog output is being used and the I/O Memory Hold Bit is set to ON to retain
analog values output externally, the values will change; the analog values out-
put externally will not be retained while Memory Cassette data is being trans-
ferred or verified. The analog output values will return to the original retained
values when the transfer or verification has been completed.
4-4 Data Link Area
Data Link Area addresses range from CIO 1000 to CIO 1199
(bits CIO 1000.00 to CIO 1199.15). Words in the Link Area are used for data
links when LR is set as the data link area for Controller Link Networks. It is
also used for PLC Links. Words in the Link Area can be used in the program
when LR is not set as the data link area for Controller Link Networks and PLC
Links are not used.
Data links can be generated automatically (using the same number of words
for each node) or manually. When a user defines the data links manually, any
number of words can be assigned to each node, and nodes can be made
receive-only or transmit-only. Refer to the Controller Link Units Operation
Manual (W309) for details.
Forcing Bit Status Bits in the Data Link Area can be force-set and force-reset.
Links to C200HX/HG/HE,
C200HS, and C200H PLCs Link Area words CIO 1000 to CIO 1063 in CP1H CPU Units correspond to
Link Relay Area words LR 0 to LR 63 for data links created in
C200HX/HG/HE(-Z) PLCs. When converting C200HX/HG/HE(-Z), C200HS,
or C200H programs for use in CP1H CPU Units, change addresses LR 0
through LR 63 to Link Area addresses CIO 1000 through CIO 1063.
I/O Memory Hold Bit
(A500.12)
Operation
OFF The analog output values in the words allocated in
memory will be cleared and the 0000 hex will be output
for the output refresh.
ON The analog output values in the words allocated in
memory will retain their values from right before the
operating mode was changed and the previous values
will be output for the output refresh.
