5.4.5

Number of HART repetitions

Definition
Specifies the number of HART frame repetitions. If the I/O module receives no response or a
response with errors to a HART frame sent to the field device, the frame is repeated, i.e. sent to
the field device again.
5.4.6

Reaction to CPU STOP

Definition
Specifies how the I/O module responds to CPU STOP or to the failure of communication between
the interface module and CPU.
5.4.7

Substitute value

Definition
The substitute value is output by the module at CPU STOP if you set the "Reaction to CPU STOP"
parameter to "Substitute value".
The substitute value must not exceed the overrange and must not fall below the underrange.
