• Set this object to the valid data length for SSI data.
• If the sum of the valid data length and the leading bits is greater than 32, SSI communications are
disabled and an SSI Data Setting Error event occurs.
• Set this object to the start bit position for single-turn data.
• If the sum of the values set for the Single-turn Data Start Bit and the Single-turn Data Length objects
is greater than the Valid Data Length object, SSI communications are disabled and an SSI Data Set-
ting Error event occurs.
• Set this object to the data length for single-turn data.
• If the sum of the values set for the Multi-turn Data Length, Single-turn Data Length, and Status Data
Length objects is greater than 32, SSI communications are disabled and an SSI Data Setting Error
event occurs.
