D8133 Data Register ROM Backup Execution Status
This special data register is used for the data register ROM backup. Stores the execution status for writing and reading.
1: Processing
2: Normal termination
3: Cannot access ROM
4: Invalid values are stored in D8184 (starting address to read) and D8185 (number of registers to read)
5: Valid data could not be read from ROM
For details, see Chapter 5 "Special Functions" – "Data Register ROM Backup" on page 5-9.
D8148, D8157, D8166 Remote I/O Communication Error Status
When a communication error occurs between the remote I/O communication slave and master, the details of the communication
error are stored in these special data registers.
D8148 : Remote I/O Slave 1 Communication Error Status
D8157 : Remote I/O Slave 2 Communication Error Status
D8166 : Remote I/O Slave 3 Communication Error Status
D8149-D8156, D8158-D8165, D8167-D8174 Remote I/O Analog Input Values
The analog input values (0 to 10 VDC) to the remote I/O analog inputs are converted to digital values (0 to 1000) and stored in the
special data registers allocated to each remote I/O slave.
When the programming language is FBD, the linear conversion can be configured for each analog input (AI). Even when the linear
conversion is configured for the analog inputs, the special data registers store the analog values (0 to 1000) before the linear
conversion is applied.
