5.4.7 Number of HART repetitions
Denition
Species 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 eld device, the frame is repeated, i.e. sent to
the eld device again.
5.4.8 Failure monitoring according to NE43
Denition
Enabling the failure monitoring changes the settings for monitoring the analog value.
Description
Failure monitoring according to NE43 can only be enabled for the measuring range 4...20 mA
HART.
• Disabled
The limits according to the S7 specications apply to the monitoring of the analog value
• Enabled
The limits for monitoring the analog value according to NE43
