Parameter bits (programmable via AS-i)function
P0Communication monitoring
P0 = 0 monitoring = off, the outputs maintain the status if communication fails
P0 = 1 monitoring = on, i.e. if communication fails, the outputs are deenergised (basic setting)
P1Input filter
P1 = 0 input filter on, pulse suppression ≤ 2 ms
P1 = 1 input filter off (basic setting)
P2Lead breakage outputs
P2 = 0 lead breakage on
P2 = 1 lead breakage off (basic setting)
P3not used
