3.
Leave the default Port number of 2001, unless you have changed the default Command
Processor port number for the SNAP Ethernet Brain. If this is the case, enter this port
number in the Port field.
4.
Click Connect to establish a link to the SNAP Ethernet brain.
5.
From the “Module #” drop-down menu in the Current PID Module Values section, select the
position of the SNAP-PID-V module on the SNAP rack.
Values associated with the module you selected should appear, and the connection status
indicator in the lower right-hand corner of the window turns green. If a SNAP-PID-V module
is not installed in the rack position you select, the value fields will display zero values.
6.
Enter a scan rate for communicating with the SNAP Ethernet brain.
This rate determines how often OptoENET PID Module Tuner communicates with the SNAP
Ethernet brain. The default scan rate of 250 ms should be suitable for most 10/100 Mbps
Ethernet connections.
IMPORTANT:
The Ethernet scan rate is
not
the same as the PID loop scan time. See
PID Module Reference” on page 17
for more information on PID loop scan times.
Step 2—Configure PID Parameters
The PID parameters you enter will depend on your particular control application. OptoENET PID
Module Tuner default settings, however, usually provide a good starting point. For complete
descriptions of SNAP-PID-V module variables and other parameters shown in OptoENET PID
Module Tuner, see
“SNAP PID Module Reference” on page 17

Click the Options button in the Ethernet Connection section (lower left part of the window).
