Channel parameters tab
The channel parameters tab (see Figure 40) shows the user parameters of the
module. It shows Signal range, OSP control and OSP value.
Channel area
Mark the Deactivate check box if the channel shall not be used.
Make the required choices in the Signal range and the OSP control drop-down
menus.
If the alternative “Set OSP value” is chosen, you can type your own value (0-100%)
in the OSP value text field.
Parameterization
The parameterization control is used for sending parameters to the module.
This is for the HART part of the module as shown in Figure 41.
General area
• Numbe
r of retries (busy response)
Writes the selected number of retries to the module. This af
fects the
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 af
fects 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.
Module area
• Manufactur
er ID code
Shows the number code for the manufacturer.
