Substitute value behavior

The Axioline E Sercos devices support the substitute value behavior for outputs. If Sercos communication fails, all device out-

puts are set to the parameterized substitute values. The configuration and behavior of the substitute values can be defined

via parameters S-0-1502.0.02 and S-0-1502.0.22.

The following substitute values are supported:

Description

Configuration

Reset all

All outputs are set to “0”.

S-0-1502.0.02 “Configuration of IO FG” bit 6 = 0 (fallback)

and S-0-1502.0.22 “Fallback value output” with the value “0”

parameterized for all process data bits.

Set all

All outputs are set to “1”.

S-0-1502.0.02 “Configuration of IO FG” bit 6 = 0 (fallback)

and S-0-1502.0.22 “Fallback value output” parameterized

with the value “1” for all process data bits.

Hold last value

All outputs keep the last value.

If S-0-1502.0.02 “Configuration of IO FG” bit 6 = 1 (freeze) is

parameterized.

Switch replace-

ment value

All outputs are set to an application-spe-

cific, parameterized value.

S-0-1502.0.02 “Configuration of IO FG” bit 6 = 0 (fallback)

and S-0-1502.0.22 “Fallback value output” are parameter-

ized with the application-specific value for all process data

bits.
