2) Parameters related to address setting
The addresses for an FSSB I/O module exist in the R area. Specify the
start address of the R area and its size with parameters.
1960 Start address of the R area for the DIs of the FSSB I/O module in the first group
1964 Start address of the R area for the DIs of the FSSB I/O module in the second group
[Data type] Word
[Valid data range] See below. The range differs depending on the PMC type.
PMC type Allowable R range
PMC–SB5 0 to 1499, 9100 to 9117
PMC–SB6 0 to 2999, 9100 to 9117
1961 Size of the R area for the DIs of the FSSB I/O module in the first group
1965 Size of the R area for the DIs of the FSSB I/O module in the second group
[Data type] Byte
[Unit of data] Byte
[Valid data range] 0 to 4 (for a basic unit only)
0 to 8 (for a basic unit plus an extended unit)
[Explanation] Only the DI data for the FSSB I/O module in the R area with the start
address specified with parameter No. 1960 or 1964 and the size specified
with parameter No. 1961 or 1965 is valid.
The data for the first group is valid when bit 4 (IO1) of parameter No. 1905
is 1. The data for the second group is valid when bit 5 (IO2) of parameter
No. 1905 is 1.
NOTE
The end address resulting from adding the size specified
with parameter No. 1961 or 1965 to the start address
specified with parameter No. 1960 or 1964 must not exceed
the data range for parameter No. 1960 or 1964. Otherwise,
no data can be transferred.
1962 Start address of the R area for the DOs of the FSSB I/O module in the first group
1966 Start address of the R area for the DOs of the FSSB I/O module in the second
group
[Data type] Word
[Valid data range] See below. The range differs depending on the PMC type.
