Functions
The State Logic Processor Module (SLP) provides real
time multi-tasking control for machine and process
applications. It can also be programmed to perform
computations, data acquisition, data communications
and operator interface functions. The SLP is programmed using the English Control Language Programming System (ECLiPS) software package. It
communicates with the PLC CPU over the backplane
and can access user and system data. Many SLPs can
be supported in a single IC693 PLC system and each
SLP can support up to 512 inputs and 512 outputs.
The PLC CPU and SLP modules together in the IC693
PLC provide a dual processor architecture which can
be used in a wide variety of applications. The SLP
provides total state logic control, including diagnostic
and simulation capablities, for those applications requiring reduced development and startup times. For
those applications where both ladder logic and state
logic programming is desired, the dual processor architecture allows a user to create both ladder logic and
state logic application programs in any combination
for efficient parallel processing solutions.
In IC693 PLC ladder logic control systems, the SLP
module can be added to provide high level machine
and process level diagnostics which can drastically
reduce total system downtime. Also, the SLP module
can provide machine or process simulation capabilities to IC693 PLC ladder logic control systems to help
reduce debug and startup times.

Installation
D Installation should not be attempted without referring to the State Logic Processor User’s Guide (see
reference 1).
D The IC693 SLP can only be installed in an IC693
The module should power up and blink the top LED,
indicating that power up diagnostics are in progress.
When the diagnostics have completed successfully the
top LED stays on.
PLC system that uses a model 331 or 341 CPU.
D Make sure baseplate power is off.
D Connect the battery to either of the battery connectors on the module. (See figure 2)
D Install the SLP Module in the baseplate. (Refer to
figure 1)
D Turn on power.
Memor y
The SLP module has 46 Kbytes of user program
memory space. Additional memory exists for Input,
Output, Register, and other variable data (see table 3).
The battery which supports this memory is located
on the SLP module as shown in figure 2.

There are no user DIP switches or jumpers on this
module for configuration. However, the module must
be configured into the overall PLC system using IC641
configurator software (reference 4). An IBM-compatible PC-XT or AT computer with the ECLiPS programming system software installed is connected to
port 1, (top port) as shown in figure 3. Port 1 is the
default programming port, but the SLP can also be
configured to be programmed through port 2. The
Default setting is 19,200 bps. Port 1 is an RS-232 port;
Port 2 is an RS-422/RS-485 port.
BATTERY
Port communication speed, parity, stop bits, and other port parameters can be configured independently
for operation with a variety of serial devices such as
operator interfaces, bar code readers, weigh scales,
etc. One of the two ports can also be configured to
communicate with the CCM2 protocol as a slave, typically for use with operator interface terminals.

Signals and their pins for both ports 1 and 2 are provided on the SLP’s single 25 pin connector. A WYE
cable provided with the SLP module breaks out the
single connector to two ports, 1 and 2, as shown in
figures 3 and 4. Refer to the State Logic Processor
User’s Guide (reference 1) for details of operation.

Status Indication
There is one visable status LED located on the SLP
module as shown in figure 2. This LED (OK) indicates
the condition of the module and is ON during normal
operation. There are two other LEDs on the board
which are not used and will always be off.

Controls
Battery
One pushbutton is provided. Push and hold the
pushbutton for less than 5 seconds will simply restart
the user application program if it was configured to
”auto-run” at power up. Push and hold for more than
5 seconds and the module is reinitialized and the user
application program must be reloaded.
A lithium battery (IC697ACC301) is installed as shown
in figure 2. This battery maintains user memory when
power is removed. Be sure to install a new battery
before removing the old battery (two connectors are
provided). Indication of a low battery is provided
through the ECLiPS programming system software
(see reference 2) and IC641 Programming Software
(see reference 4).
