VNC Account
MicroVission panels can be accessed remotely by using a
VNC client over TCP/ IP network. This section allows the
operator to change default VNC password and VNC port
number. For more information, see Figure 12-2.
• New Password : The operator will add the password
by touching the entry box and typing the password
via the pop-up.
• Verify New Password : The operator will re-enter
the password by touching the entry box and typing
the password via the pop-up keyboard.
• Port Number : The operator will change the port
number for the VNC server by touching the entry
box and typing the port number via pop-up key-
pad. Default port number is 5900. The operator can
assign the port number in the range from 5900 to
6000.
Alarms and Trips
The “Idle Time Trip” checkbox works in conjunction with
the “High Level Shutdown” digital input. If checkbox is
enabled, when the compressor is in idle state and this
digital input is off, the compressor should give a trip
message.
Communication
The communication section is the control center for all
communications to the MicroVission panel. It is possible
to have multiple modes of communications enabled and
used. However, only one mode can be used to control
the MicroVission, which would be the one selected in
the “Active Remote Control” drop-down box.
For a complete list of communication registers, see
Appendix B, Communication Table.
Active Remote Control
Select the mode of remote control. The operator any
one option from Direct I/O, Ethernet, Serial and None.
Direct I/O
Enables the Direct I/O Inputs. When checkbox is en-
abled, the operator can select any one Direct I/O option
from “Auto Control” and “(Digital) Manual Control”.
• Auto Control : This option will allow the operator to
run compressor in Direct I/O Auto Run Mode. The
algorithm will use setpoints of Compressor Control
screen for loading & unloading of compressor
cylinders.
• (Digital) Manual Control : This option will allow the
operator to run compressor in Direct I/O Manual
Run Mode. The algorithm will monitor the state of
“Remote Increase” & “Remote Decrease” Digital
Inputs for loading & unloading compressor cylinders
respectively. If “Remote Increase” Digital Input is ON
& “Remote Decrease” Digital Input is OFF then the
compressor will load one step. Similarly, if “Remote
Increase” Digital Input is OFF & “Remote Decrease”
Digital Input is ON then the compressor will unload
one step.
The operator should ensure following conditions are
met to run the compressor in Direct I/O Run Mode:
1. “Direct I/O” checkbox is enabled
2. “Active Remote Control” setting is set to “Direct I/O”
3. “Remote Start/Stop” Digital Input is ON
Once above conditions are met, the operator can
start compressor in Direct I/O Run mode by pressing
on “START” button in Main screen and then selecting
“Remote” option in pop-up window.
Run Permissive
When this checkbox is enabled, MicroVission moni-
tors the “Remote Start/Stop” Digital Input. If “Remote
Start/Stop” Digital Input is energized (turned ON), the
compressor can start in the selected run mode (Auto
/ Manual / Remote). If the “Remote Start/Stop” Digital
Input is de-energized (turned OFF), the compressor will
wait until the Digital Input is energized.
When this check box is disabled, MicroVission will not
monitor the state of “Remote Start/Stop” Digital Input
during the compressor start.
