Figure 56: Control panel for process connection
In this second row of the panel, it is possible to set the automatic simulation of command responses
and command reactions (drop list "Type"):
Figure 57: Automatic simulation - type
The "Command response" option gives the user the possibility to pre-define the command response
(positive or negative confirmation) that the RTU500 sends back to host systems when a command
output to a disconnected from process (in controlling direction) signal is received. The user shall
select an option from the "Value" drop list and click on the "Apply" button.
Figure 58: Automatic simulation - command response
In the user interface, the text of the signals for which the automatic simulation of pre-defined com-
mand responses are set turns green. If the mouse pointer is placed over these rows, a tooltip shows
the value of the pre-defined command response (Fig. 59).
Figure 59: Setting automatic simulation of command responses
The second type of automatic simulation that the user can set in the control panel is "Command
reaction". This is the simulation of the process information signal defined by the user in RTUtil500 as
response indication for SCO and DCO objects (Process information parameter, SCO/DCO - General
parameters). That process information signal must have been disconnected from process as well
by the user.
The user shall select the value with which the command reaction is simulated (same or opposite value
to the output command's value) and, optionally, the delay in milliseconds between the command
response and the command reaction (Fig. 60). Finally, the button "Apply" must be clicked.
