We will do the same thing again, press the IN key again and enter an

I0. The display will now look like

the 1

st

screen in Figure 5.10

Figure- 5.10: Entering Input Functions and Starting Output Function.

Entering The Program

We now want to complement the second

I0. This is done by selecting the NOT function by

pressing the NOT key (! appears). Now we want to OR these two terms together. Select OR by pressing
the OR key (¦ appears). See the 2

nd

screen in figure 5.10 for these two entries (the MOR

E

key navigates).

The last function to enter is the output to which the result is sent. Because we have defined relay 8 for this,
we want to enter an

O15. See Table 5.4, for a list of all States and Events. Press the OUT key to select

an Output function. You will be prompted for the ID number. Enter a 15 for the ID#. Press the 10 key
once for the 1, and the 1 key five times for the 5 (See the 2

nd

screen in figure 5.10). Follow the digit entries

with the ENT key to accept the digit entries. The display will look like figure 5.11.

Figure- 5.11: Finishing the Output Function Entry.

Entering Tokens


Press (rung) ENT to accept complete rung. Result is in screen 2 of figure 5.11. Rung 012 is now

finished and saved as part of the I/O Setup program. Use BAK to leave the CHG/EDT line process. The
relay number 8 will close at this point (you can probably hear it click on). The ID (I/O program checksum)
should be: B07587. This finishes entering this I/O program. Return to the RunTime screen by pressing the
fixed STATUS key.

Example 2 - Factory Installed I/O Program

This I/O program is the one that is shipped standard with the STC-2000A. Its functions are:

Factory Set Outputs

Output 1 Crystal Fail - This relay provides a contact closure whenever the film program stops because of

mapped (selected) sensors failing to operate properly (or sensors exceeding the user defined
operating range). A STOP: XTAL message will be displayed on the LCD display to alert the user
of this condition.


Output 2 Source #1 Shutter Relay - This relay is intended to provide control of the source shutter. It is

generally activated during the deposition phase when source #1 is active.


Output 3 Xtal 2 Select - Output 3 is enabled when sensor 2 is an active sensor.

Output 4 Thickness Setpoint - This relay provides a contact closure whenever the accumulated thickness

display value equals or exceeds the thickness setpoint parameter value.
