Sealevel’s SeaI/O software is provided to assist in the development of reliable
applications for the Sealevel Systems family of digital I/O adapters. Included on the
SeaI/O CD are driver functions for use in accessing the I/O as well as helpful
samples and utilities.
Programming for Windows
The SeaI/O API (Application Programmer Interface) provides a variety of useful
high-level function calls implemented in a Windows dynamic link library (DLL).
The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under
“Application Programmers Interface”. This help file also includes detailed
information dealing with installation / removal of the software and information
about latency, logic states, and device configuration.
For C language programmers we recommend using the API to access the PLC-
16.PCI. If you are programming in Visual Basic, using the ActiveX control
included with SeaI/O is advised.
Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are
included with SeaI/O. Further documentation on these samples can be found by
selecting “Start/Programs/SeaIO/Sample Application Description”. Information
about where the files are physically stored on your disk is also included in this same
file.
Programming for Linux
SeaI/O for Linux consists of two major parts: a kernel moduleand a library. The
kernel module is a simple IO pass-through device, allowing the library to handle the
more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’
format and can easily be compiled and included in the kernel build.
Digital I/O Interface
The PLC-16.PCI provides two parallel input/output (I/O) ports. The ports are
organized as ports A, B, C, and D. Port A is an input port interfaced to optically
isolated inputs, while port C is the relay output port.
Port A is an eight bit input port connected to optically isolated input sensors. Each
sensor can be used to interface a voltage input and then sense whether the voltage is
on or off. Each sensor is isolated (with respect to a common ground) from every
other sensor, and also isolated with respect to the host PC ground. This means that
signals such as low-level AC line voltage, motor servo voltage, and control relay
signals can be ‘sensed’, or read by the PC, without the risk of damage due to ground
loops or ground faults.
Each sensor input pair has a current limiting resistor that is used to limit the input
current to the opto-isolator. The opto-isolator has two ‘back-to-back’ diodes
internally. This allows AC or DC signals to be sensed, regardless of polarity. When
the applied voltage is high enough to cause the led in the opto-isolator to turn-on, the
output of the opto-isolator goes low (0 volts) and the signal is read as a low logic
level (binary 0) by the PC. When the input signal is too low to turn on the optoisolator, the output goes high and the port bit is read by the PC as a high logic level
(binary 1).
The input impedance of each isolated input is approximately 1K ohms
(factory default). The opto-isolator requires approximately 3mA to turn on. The
maximum input current is 50mA. There are two things to consider when selecting
the input resistor. The first is turn on voltage for the circuit to sense, and second is
the maximum input voltage. Maximum input voltage must not provide too much
power to the input resistor, and must also not overdrive the opto-isolator input
current specification. The following formulas apply:
Turn on Voltage = diode drop + (turn on current) x (resistance)
[Ex: 1.1 + (.003) x R]
Input Current = ((input voltage)-1.1V) / (resistor value)
Maximum voltage = 1.1 + square root of (.25(resistor value))
The following table shows the ranges associated with the resistor.
Input Resistor Turn-On Input Range Max Input Max Current
1KΩ
3.0V 5.0 – 24.0V 30V 29mA
Note: The turn-off voltage for all resistors is less than 1V.
Because through hole resistors are utilized, they cannot be easily replaced. If
modification is necessary, Sealevel can do this for an additional charge.
Important: The input circuits are not intended for monitoring 120-volt AC circuits.
In addition to being too high a voltage for the circuits, it is dangerous to have that
high a voltage on the card.
The PLC-16.PCI provides 8 Form C (SPDT) Electro-mechanical relays. These
relays have three connections: Normally Open (NO), Normally Closed (NC) and a
Common. The relays are all de-energized at power-on. Data to the relays is latched
by a write to the base+2 address. On/off status of the relays can be read back by a
read at the base+2 address.
In systems where the user’s program has direct access to the hardware (i.e. DOS) the
table below gives the mapping and functions that the PLC-16.PCI provides.
Function AvailablePortAddress HexPort Type
RD A Base+0 Input Port (Opto Input)
B Base+1 Not Assigned
RD/WR C Base+2 Output Port (Reed Relays)
D Base+3 Not Assigned
RD = Read, RD/WR = Read or Write
Reading the Inputs
The inputs are active Low. If no voltage is applied across one of the differential
inputs it returns a binary one (1) on that bit. If an AC or DC voltage is applied it
returns a binary zero (0) on that bit.
The output ports are the only ports that can be written. The relays on a standard
PLC-16.PCI are normally open. To close a relay a binary one (1) must be written to
the appropriate bit.
Reading the Outputs
The relay ports can also be read to determine the status of the various relays. A read
will return the ones complement (or opposite) of the value that is currently written to
the port.
Register Description
All ports are set to input after reset or power up.
When enabled, interrupts are generated on Port A bit D0.
IRQEN
IRC0
IRC1
Interrupt enable 1 = enabled 0 = disabled ( 0 on power up )
Interrupt Mode Select Table
Interrupt source is Base+0 bit D0. When selecting the Interrupt Type, always disable
interrupts prior to changing or setting states. This will help prevent inadvertent or
unexpected interrupts from occurring.
Warning: When using the High and Low Level interrupts, an interrupt occurs when
input D0 changes to either a High or Low state. This will cause the computer to
remain in an interrupt state until the input state changes.
Interrupt mode select, see table below
Interrupt mode select, see table below
Interrupt Read
Reading the Interrupt Status port (Base+5) clears any interrupt pending.
The table below describes the pin out for the HD44 Female connector on the 8011

Another option for termination of the PLC-16.PCI is the Terminal Block Kit (Item#
KT108). This kit includes an HD44 Male to HD44 Female six-foot cable (Item#
CA185) and a 28-Pin Terminal Block (Item# TB08-KT). The silk screen with
diagram is shown on the following page.
The CA185 cable is wired straight through, one-to-one.
The terminal block groups the common connections of the PLC-16.PCI into groups
of four as shown:
RC1 (Relay Common 1) ties together the ground pins for physical relays K1 –
K4 (logical D0 – D3) e.g.: HD44 pins 16,17,18 and 34 are connected to simplify
field wiring
RC2 (Relay Common 2) ties together the ground pins for physical relays K5 –
K8 (logical D4 – D8) e.g.: HD44 pins 19,20,21 and 22 are connected to simplify
field wiring
The other eight screw terminals in each group (16 total) are used to wire to the
NO (Normally Open) or NC (Normally Closed) side of the relays. These are
labeled K1 – K4 and K5 – K8
IC1 (Input Common 1) ties together one side of the input pins for D0-D3 and IC2
(Input Common 2) ties together one side of inputs D4-D7 to simplify field wiring
The other four pins in each group (8 total) are used to wire to the inputs. These
Part Number CA184 is an optional cable for use with the PLC-16.PCI. The CA184
has an HD44 connector that breaks out to one DB37 Female connector for Inputs
and one DB37 Male connector for Outputs. This cable was designed to make our
products more easily integrated into systems that may have previously used Sealevel
legacy I/O interface products. The CA184 cable mimics several of the pin-out
options found on Sealevel PCI and ISA legacy products and provides a direct
connection to the 37 pin Terminal Block, Part Number TB02-KT. The following
