Example 3: Error Data in Register C012h
When error data enters register C012h in the L
ON
W
ORKS
interface module, the data is transferred to a link register in the
CPU module as illustrated below:
Example 4: I/O Counts in Link Register L*13
When 8 bytes (output) and 4 bytes (input) are selected as the transmit and receive data quantities in
WindLDR
Function
Area Settings, respectively, these values are stored to link register L*13 in the CPU module, and the data is transferred to
register C013h in the L
ON
W
ORKS
interface module as illustrated below:
Note:
Link register L*13 is for read only. Do not write data into L*13.
Example 5: Software Version in Register C018h and Expansion Module ID in Register C019h
When a software version number is stored to register C018h in the L
ON
W
ORKS
interface module, or when an expansion
module ID is stored to register C019h in the L
ON
W
ORKS
interface module, the data is transferred to a link register in the
CPU module as illustrated below:
