Direction Monitoring
Defines the allowable direction if Safe Direction Monitoring is enabled.
“Pos Always” (1) – Positive always
“Neg Always” (2) – Negative always
“Pos in SLS” (3) – Positive during safe limited speed monitoring

Options: 0 = “Disabled”
0 = “Disabled”
1 = “Pos Always”
2 = “Neg Always”
3 = “Pos in SLS”
4 = “Neg in SLS” RW 8-bit
