communication between the module and the HART instrument. Valid numbers
are 0 - 10. This applies for a busy response.
If the communication with the HART instrument fails when the default value is
used, increase the value to ensure a better performance.
• Number of retries (other error)

Writes the selected number of retries to the module. This affects the
communication between the module and the HART instrument. Valid numbers
are 0 - 10. This applies for other error.
Service
The service control is used for sending special functions (commands) to the

HART part of the I/O module. The Service tab is as shown in Figure 42 .
