General Description

The Valco Serial Valve Interface (SVI) is a de vice that converts commands
from a computer, via a serial port, into positional control for our two position
and multiposition valve actuators. Each SVI can control up to four air or
electrically actuated two position valves and two electrically actuated
multiposition valves. The SVI has two serial port connections (one male,
one female) which allow daisy-chaining of up to eight SVI’ s on a single serial
communication port. In addition to controlling valves, the SVI can be used to
control other devices which require logic level BCD or single line inputs.

The SVI is a packaged unit which includes an external 12 VDC 200 MA wall­mount power supply. There is no need to open the computer to connect the
SVI, because its DB-9 to DB-9 RS-232 cable connects to any available serial
port on the back of the computer. It also includes an interface cable for
V alco two position actuators, and tw o 20-pin IDC connectors for installation
on the interface cable which comes as part of the multiposition standard
electric actuator. For air actuated v alves , optional interf ace cables are
available f or the Valco Digital Valve Interface (DVI), which converts electrical
signals to pneumatic pulses. (V alco product number I-22239).

While the SVI can be operated by virtually any computer with an RS-232
port, the software supplied with this package is written for PC’s . The SVI is
supplied with Vcom software .

Software CD

The SVI can operate in one of two different modes, determined by the
position of the jumper on connector CO14 on the SVI main board during
power up. In the Option 1 position (the factory setting) the Single Device
Mode is selected; in the Option 2 position, the Multiple Device Mode is
selected. See Drawing 22110, page 14 for a complete list of the SVI jumper
options and the factory settings.

Single Device Mode

The single device mode, which is the factory-preset mode, requires a
dedicated Serial Communications Port on the host computer for each SVI.
Three optional baud rates can be selected by jumpers on the SVI main
board, with a factory setting of 9600 baud. See Drawing 22110, page 14.

Multiple Device Mode

The multiple device mode allows up to eight SVIs to be daisy-chained from a
single serial communications port on the host computer. (Figure 1) In this
mode the SVI has a fixed 9600 baud rate. Connector CO11 on the SVI main
board selects an ID of 0 to 7 which is used to distinguish each device. (Each
SVI in the daisy chain must have a diff erent ID.) The communications board
connector CO14 jumper must be changed to the PASS THRU position f or all
SVIs on the daisy chain except for the last device, which should be set to
the END MODULE position to properly terminate the daisy-chain. See
Drawing 22110, page 14 for a complete list of the SVI jumper options.

CAUTION: For proper startup, make sure that all the
jumper settings in the SVI are correct, and that all exter­nal devices have been disconnected or are turned off
before applying power to the SVI.

The SVI has two communication port connectors labeled “COM 1” and “COM
2”. The RS-232 cab le provided connects the COM 1 connector on the SVI to
the serial port connector on the PC. If the computer serial port connector is
a DB-25 connector, then a DB-25 FEMALE to DB-9 MALE adapter connector
or cable is required. Most computer or electronic stores carry this adapter.

The RS-232 cable with Male and Female DB-9 connectors must be wired
“straight through”, or pin to pin;
Only Pins 2, 3, and 5 are used by the SVI; they are functionally defined
as TRANSMIT, RECEIVE, and GROUND , respectiv ely,

Electric Actuator Connections

Standard Two Position Electric Actuators

To connect the SVI to a two position standard electric actuator, use the two
position interface cable. Plug one end of this cable into the connector on the
top of the SVI which is labeled V1 V2 V3 V4. The other end of the cable has
four Molex connectors which are addressed b y the SVI as V1 through V4.
These Molex connectors plug directly into the remote switching cable on the
back of Valco’s standard two position electric actuators.

Any V alco two position standard electric actuator with a serial number above
19000 allows the option of positive dual-position feedback to the SVI.
T o enab le this feature:

1 . Unplug the actuator. Use a pair of pliers to compress and remov e the

cable strain relief devices from the back of the actuator cover . Remove
them from the cables to allow the cables to travel freely through the holes
in the cover.

2 . Remove the four phillips screws which secure the actuator co ver .

(One must be accessed through a hole in the black mounting bracket)

3 . Slide the cover back far enough to allow access to the small dipswitch

on the board next to the connectors for the manual switching cable, and
change the position of the switch.

4. Put the cover back in position, replace the four screws, and reinstall the
strain relief devices.

In this mode, the clear wire carries a logic high when the actuator is in
Position A (LOAD): the white wire carries a high when it’s in Position B
(INJECT).

Microelectric Two Position Actuators

Microelectric two position actuators have a built-in serial port, and
therefore do not require the SVI for serial port control. However, they
can be connected to an SVI if you are upgrading a system from standard
electric actuators and don’t want to change the existing SVI software.

Cable I-23196 adapts any of the Molex connectors (V1 through V4) on
cable I-22041 to the digital input port on a two position microelectric actuator.
If only two position microelectric actuators are to be used, then optional
cable I-23783, which provides four direct connections to the SVI, can be
substituted for cable I-22041.

Standard Multiposition Electric Actuators

Each standard multiposition electric actuator is shipped with an external
interface cable. This cable has an IDC 20-wire connector on one end, with
the other end unfinished to allow user-selected termination. To connect the
multiposition actuator to the SVI, install an IDC 20-wire connector on the
unfinished end. Plug one end of the cable into the multiposition electric
actuator and the other end into the connector on the SVI labeled either V5
or V6. Two multiposition valves may be used simultaneously.

Two Position Air Actuator Connections

The SVI can be used to control up to four Valco two position air-actuated
valves by connecting the SVI to the Valco Digital Valve Interface (DVI). The
two position electric actuator cable can be adapted to control a DVI using
this procedure:

1. Use a wire cutter to remove the plastic Molex connector from the SVI
connecting cable.

2. With a wire str ipper, remove insulation from the red, blue, and black
wires in each of the DVI ribbon cables and the corresponding SVI ribbon
cable.

3. Use solder or cr imp-on connectors to join the DVI ribbon cable to the SVI
ribbon cable as shown in the table belo w.

SVI Control of Other Electrical Devices

NOTE: The follo wing information is not intended for users unf amiliar with low
power digital circuitry and proper isolation techniques.

The V1 PosA output on the SVI has special capabilities. While all other
two position outputs are transistor devices with 30 volt 50 milliamp (open
collector) outputs, the YELLOW wire (pin 4 of the Molex connector) on the
V1 output is a relay contact closure to ground. It can be used to drive loads
of up to 48 volts at 1/2 amp.

Additionally, the ground reference brown wire (pin 3 of the Molex) can be
jumpered on CO12 on the SVI main board for a 12 VDC output which is
sufficient to power small solenoids or other devices of up to 100 ma con­tinuous current. (Or 200 ma on short duty cycle applications.) See Drawing
22110, page 14 for detailed information.

Installation

CAUTION: When the SVI Valve 1 output is jumpered for
12 VDC output, remove the plastic Molex connector
from the SVI cable to insure that damage will not result
from an accidental connection to a Valco two position
electric actuator or DVI.

Before using the valv e outputs to driv e an y load in excess of 12 VDC, the
jumper on connector CO13 must be changed to the OFF position. This
effectively removes the internal 12 volt diode clamp on the two position
valve outputs, and requires the installation of external reverse diode clamp­ing on all inductive loads driven by these outputs.

The two position valve outputs have a jumper-setable option which allows
for the output signal to be continous or to be de-asserted following an
actuation command. When this “timeout” is enabled the signal is asserted
for 150 milliseconds, unless the valve is configured to require feedback. In
that case, the signal will assert until the feedback is received, to a maximum
of four seconds. After four seconds, a positioning error will be indicated.

The SVI as received from the factory has all the outputs set for the timeout
option. If a valve output is to be used to control something other than a
Valco actuator, it may be desireable to disable the timeout function by
arranging the jumpers as indicated in Drawing 22110, page 14.

CAUTION: All outputs from the SVI are internally refer ­enced to a common ground; therefore, all external loads
should be electrically isolated from high voltage power
sources for maximum personal safety and proper equip­ment operation and protection.

Communicating with the SVI using Vcom

Vcom is a simple serial port utility that can be used to send a sequence of
text strings at timed intervals. The times and associated text strings are
stored in method (.mth) files. It is also possible to send individual strings,
entered using the keyboard, and view an y reply .

1. Selecting a serial port

Open a serial port by selecting Utility > Com.Port from the menu.
The next time the program is run, the selected serial port will be opened
automatically .

2. Creating a new file

If you are creating a new method file, select File > New from the menu.
Enter the times and the command strings into the edit box in the method
window as described in “Editing a file,” below .

3. Opening a file

If you wish to run an existing method file, open it my selecting File > Open
from the menu.

7

4. Editing a file

If the newly opened file needs to be edited, click the “Edit” checkbox to enter
the edit mode.

Entering a time

Times are entered in the hour:minute:second format, using any non-numeric
separator.

For example:

20 = 20 seconds into the method run

2.10 = 2 minutes and 10 seconds into the run
1;30.4 = 1 hour, 30 min utes, and 4 seconds
01:30:04 = 1 hour, 30 minutes, and 4 seconds

It is not necessary to enter the times in order. The y will be put in order when
you exit the edit mode.

Entering a command

The command is entered after the corresponding time, separated from the
time by a space or tab. Commands are discussed in the next section.

For example:

20 V1A Instructs the SVI to move valve 1 to Position A at

20 seconds into the method run

2.10 V1B Instructs the SVI to move valve 1 to Position B at

2 minutes and 10 seconds into the method run

1;30.4 V68 Instructs the SVI to move valve 6 to Position 8 at

1 hour, 30 min utes, and 4 seconds into the method run

Transmitted Command Types

The following is a list of the command letters for the types of commands
available for controlling the SVI. Each letter represents a specific function
the SVI will perform. The commands are sub-divided into two g roups:
commands directed to specific valves, and commands directed to the SVI.

Commands for Specific Valves

V Indicates a Valve positional command. It is used to direct the SVI to

move a valve to an indicated position.

S Indicates a valve Status request. It tells the SVI to transmit the current

position of the indicated valve to the host.

L Indicates a valve command to Limit the number of positions to which the

SVI will rotate a multiposition valve.

F Indicates a command to check valve status after a positioning command

is completed and to provide Feedback as to the functional success or
failure of the command.

N Indicates a command to igNore valve status after the execution of a valve

positioning command.

Commands for the SVI

R Represents a command to the SVI to Reset, or perform a re-initialization

of the device. It is equivalent to tur ning the power off and back on again.

E Represents an Echo control command to the SVI. The echoing of

position arrival (closed loop feedback) of all valves on an SVI can be
deactivated or reactivated using this command.

/? Causes a command list to be echoed to the serial port.

Transmitted Command Syntax

For the purpose of learning the transmitted command syntax, it is easier to
consider only SVIs in the single device mode. It is also helpful to divide the
commands into three groups: commands with a command letter, a valve
number, and a v alve position (three v ariables); commands with a command
letter and a valve number (two variables); and commands with fixed syntax
(no variables).

No spaces are allowed between any portion of a single
command.

Command Letter/Valve Number/Position

In these commands, valve numbers 1 through 6 are used, depending on the
valve to be addressed. For two position valves (1 through 4), the position
variables are A and B. (L for Load and I for inject may be substituted for A
and B, but this creates the potential for confusion between Limit and Load.)

Communicating with the SVI using Vcom

For multiposition valves (5 and 6), positioning is defined using the numbers 1
through 16, limited by the number of positions of the valve. (If an invalid
valve position request is sent, a response of BCMD appears, indicating a
command which cannot be executed.)

Examples

Command: V1A

Instructs the SVI to move valve 1 to Position A.
The first variable is the command letter, which indicates that

this is a Valve positioning command. The second variable
directs the command to valve 1, while the third instructs the
SVI to move it to Position A. This command would function
equally well as V1L.

Command: L512

Instructs the SVI to ignore any command which would move valve 5
to any position past position 12.

The command letter indicates that this is a request for a position
Limit, which is directed, as the second variable indicates, to valve 5.
The third variable sets that limit at Position 12.

9

Command: V68

Instructs the SVI to move valve 6 to Position 8.
The first variable indicates that this is another example of a Valve

positioning command. The second variable directs the command to
valve 6, which is a multiposition valve. This means that the pos­itional variable must be numerical: A or B will not work. In this
example, Position 8 is selected. (A zero may precede a single digit
positional command, so this command would also work as V608.)

Command Letter/Valve Number

In these commands, valve numbers 1 to 6 are again used, depending on the
valve to be addressed.

Examples

Command: S1

Requests the SVI to transmit to the host the current sensed status
of valve 1. If the valve status cannot be read, it will return an error
status. (See page 10)

Command: F2

Requests the SVI to verify all attempts to position valve 2, and to
provide serial port status feedback to the host.

Command: N3

Requests the SVI to ignore the status feedback on valve 3 following
any actuation command.

Command: L5

Requests the SVI to transmit to the host the current limits set for
valve 5. NOTE: This command is only valid f or the m ultiposition
actuators, on valves 5 and 6.

Communicating with the SVI Using Vcom

10

Fixed Syntax Commands

These commands are used only with the fixed syntax as they are listed
below. There are no valve or position variables.

Command: R

Initiates a RESET procedure. Once initiated, the device requires up
to four seconds before it responds with a reset acknowledgment.

Command: EON

Initiates ECHO ON. After the receipt of this command, the SVI will
echo a serial port response to all valve positioning commands.

Command: EOF

Initiates ECHO OFF. After the receipt of this command, the SVI will
only echo a serial port response for valve functions which are
configured for feedback and fail to complete a positional command.

Multiple Device Mode Commands

All commands transmitted to any SVI set for the Multiple Device Mode must
be prefaced by the ID of that SVI. Otherwise the syntax conventions
exactly parallel those illustrated in the previous examples. The ID is se­lected on CO11 as described in the section “Multiple Device Mode”, on
page 2.

Examples

Command: 7V510

Instructs SVI 7 to turn valve 5 to Position 10.
The first variable, “7”, is the SVI ID. The second variable is the

command letter, which tells the SVI that this is a Valv e positioning
command. The third character is the valve number, telling the SVI
that valve 5 is to be controlled. The last two characters represent
the position to which the valve will be turned.

Command: 2V3A

Instructs SVI 2 to turn valve 3 to Position A.
In this example, the ID is 2. The command letter indicates that this

is another Valve positioning command, for valve number 3. The
position variable indicates that the valve will be turned to Position A.
This command would function equally well as 2V3L.

Command: 0S1

Requests SVI 0 to give the current position status of valve 1.
The first variable indicates that the device which has an ID of 0 is

being addressed. The S is the command letter for Status request,
and the 1 indicates that valve 1 is to be queried. There is no
positional information needed as this command is a query for
current valve positional status.

Responses Received from the SVI

The SVI transmits responses to host commands or to perceived changes
in valve status. It also echoes commands which are not directed towards
itself. While the syntax of the response is identical to that of the transmitted
command, the content may differ. This permits differentiation of critical
responses from echoed commands.

The SVI responses are listed below:
RST This response alwa ys follows an SVI reset. The reset can be the

result of a power failure, or the receipt of the R command from the
host.

EON This is the SVI’s response to the identical command from the host.

It indicates that all commands to the SVI will generate a serial port
response.

EOF This is the SVI’s response to the identical command from the host.

It indicates the SVI will generate a serial port response only to
bad commands, or positioning commands to valves configured
for feedback which fail to indicate successful positioning.

Communicating with the SVI using Vcom

11

BCMD This is the SVI’s response to host commands which are directed

to the device, but cannot be executed. An example might be a
numeric positional command sent to a 2 position valve, or a
positional command to a multiposition valve which exceeds its
set limit, etc.

S This letter represents a status response. It may be preceded by

the device ID depending on the Mode setting. It in turn always
precedes one of the following: (1) a valve number and the sensed
position, (2) an error indication (represented by the letter E) which
results from as invalid position sense, or (3) a motion indication
(represented by the letter M) which results from the sensing of the
run line asserted on the multiposition valves.

This response is initiated by a status request or a valve positioning
command (if the echo is enabled) from the host. If feedback is not
required, the response following a valve command will reflect the
attempted position rather than a sensed status.

L This letter represents a limit command response, and follows a limit

request or a limit set command. It may be preceded by a device ID,
but is always followed by a multiposition valve number (5 or 6) and
the last limit position set for that valve.

Remember, all the responses above may be preceded by the SVI ID
number.
