1963 Size of the R area for the DOs of the FSSB I/O module in the first group
1967 Size of the R area for the DOs of the FSSB I/O module in the second group
[Data type] Byte
[Unit of data] Byte
[Valid data range] 0 to 3 (for a basic unit only)
0 to 6 (for a basic unit plus an extended unit)
[Explanation] Only the DO data for the FSSB I/O module in the R area having the start
address specified with parameter No. 1962 or 1966 and the size specified
with parameter No. 1963 or 1967 is valid.
The data for the first group is valid when bit 4 (IO1) of parameter No. 1905
is set to 1. The data for the second group is valid when bit 5 (IO2) of
parameter No. 1905 is set to 1.
NOTE
The end address resulting from adding the size specified
with parameter No. 1963 or 1967 to the start address
specified with parameter No. 1962 or 1966 must not exceed
the data range for parameter No. 1962 or 1966. Otherwise,
no data can be transferred.
1968 Address of the R area for DO alarm detection
[Data type] Byte
[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
[Explanation] This parameter specifies the address indicating which unit has detected
a DO alarm.
