10.3

Substitute value behavior

The substitute value behavior is set via the IO module in slot 2. The following parameters are available:

Byte order: Substitute value pattern

Non-turned byte order:

Rotated byte order:

10.4

Swap byte order

The byte order of the process data can be changed with the following paramaters on the IO module in the slot 2.

Parameter

Possible values (bold = default)

Description

Failsafe substitute value

behavior

0 = all outputs reset (default)

Substitute value behavior for all outputs

1 = all outputs set

2 = hold last value

3 = substitute values

Failsafe substitute values

0 = zero (default)

Specification of a substitute value pattern for all out-

puts. In order to use this parameter, you must first set

the “Substitute values” in the “Failsafe substitute

value behavior” parameter.

The parameter "Failsafe substitute value" controls regardless of the setting "byte ordering exchange" always

the same outputs. Take this into account when calculating the substitute value.

Description

Swap byte order

With this parameter, the process data can be rotated, ie the byte swap. The param-

eter "Failsafe substitute value" remains unaffected.
