4-7
Serial PLC Link Area
The Serial PLC Link Area contains 90 words with addresses ranging from
CIO 3100 to CIO 3189 (bits CIO 3100.00 to CIO 3189.15). Words in the Serial
PLC Link Area can be used for data links with other PLCs.
Serial PLC Links exchange data among CPU Units via the built-in RS-232C
ports, with no need for special programming.
The Serial PLC Link allocations are set automatically by means of the follow-
ing PLC Setup in the Polling Unit.
• Serial PLC Link Mode
• Number of Serial PLC Link transfer words
• Maximum Serial PLC Link unit number
Addresses not used for Serial PLC Links can be used in programming, the
same as the Work Area.
Forcing Bit Status
Bits in the Serial PLC Link Area can be force-set and force-reset.
Serial PLC Link Area
Initialization
The contents of the Serial PLC Link Area will be cleared in the following
cases:
1.
When the operating mode is changed from PROGRAM mode to
RUN/MONITOR mode or vice-versa and the IOM Hold Bit is OFF
2.
When the power is cycled
3.
When the Serial PLC Link Area is cleared from the CX-Programmer
4.
When PLC operation is stopped when a fatal error other than an
FALS(007) error occurs (The contents of the Serial PLC Link Area will be
retained when FALS(007) is executed.)
4-8
DeviceNet Area
The DeviceNet Area consists of 600 words from CIO 3200 to CIO 3799.
Words in the DeviceNet Area are allocated to Slaves for DeviceNet remote I/O
communications.
Words are allocated to Slaves using fixed allocations according to fixed allo-
cation settings 1, 2, and 3. One of these fixed areas must be selected.
