Some models transfer data in both directions, from the DM Area to the Unit
and from the Unit to the DM Area. See the Unit's Operation Manual for details
on data transfers.
These 100 words are generally used to hold initial settings for the CPU Bus
Unit. When the contents of this area are changed from the program to reflect a
change in the system, the Restart Bits (A50100 to A50115) for affected Units
must be turned ON to restart the Units.
CPU Bus Unit
Transferred each cycle
and when necessary.
The CMND(490) instruction can be added to the ladder program to issue a
FINS command to the CPU Bus Unit.
CPU Bus Unit
FINS command transmission
FINS commands can be transmitted to CPU Bus Units in other PLCs in the
network, not just the local PLC.
Serial Communications Unit
CPU Unit
Command transmission
CPU Bus Units are initialized when the PLC's power is turned on or the Unit's
Restart Bit is turned ON. The Unit's CPU Bus Unit Initialization Flag (A30200
to A30215) will be ON while the Unit is initializing.
Cyclic I/O refreshing will not be performed for a CPU Bus Unit while its Initial-
ization Flag is ON.
