Chapter 1 State Logic Processor Description

1

The State Logic Processor (SLP) is a module which inserts into a Series 90t-30 PLC chas­sis. This module has the State Engine operating system to execute State Logic control
programs produced by the ECLiPS programming software package.

The SLP exists together with a CPU module in the Series 90 -30 PLCs. The CPU must be
a model 331, Revision 3.03 or higher. The CPU may execute a Relay Ladder Logic Pro­gram at the same time the State Logic Processor is executing a State Logic Program. The
SLP manipulates the CPU memory space and the CPU controls the I/O during its normal
cycle of operations. More than one SLP can be installed in one Series 90-30 PLC system,
although the SLP must be installed in the main rack with the CPU.

The software products, ECLiPS and OnTOP, are the user interfaces to the SLP. ECLiPS is
a program development and on-line monitoring software product which runs on an
IBM-PC compatible computer. OnTOP, the On-Line Troubleshooting Operator Pro­gram, also runs on an IBM-PC compatible computer. For questions about programming
or on-line functions, see the ECLiPS or OnTOP User’s Manuals.

Figure 1-1. SLP in Series 90-30 Chassis

The 90-30 SLP uses an 8 mHz 80C188 microprocessor and has two serial ports, port 1 is
and RS-232 port and port 2 is an RS-422/485 port. One port is designated the program­ming port, to be used to communicate with ECLiPS or OnTOP. The other port may be
configured to be a CCM port, communicating to a host computer using the CCM proto­col. See the section on Serial Communications for more information on using the serial
ports.

There are three LED indicators located at the top front edge of the SLP. The top LED is
the status indicator for the SLP. During power-up this LED flashes while the SLP is run­ning its diagnostic checks. If this LED is off, either the power is off, there is some hard­ware malfunction of the SLP, or there is no CPU present in the Series 90-30 PLC system.
When the LED is on, the SLP is functioning normally.

Operational Description

The State Logic Processor (SLP) uses areas in the CPU memory for I/O references and
Register values. The SLP and the CPU communicate this information over the PLC
backplane.

When a Ladder Logic control program and a State Logic control program are running at
the same time, the State Logic and Ladder Logic programs should not be controlling the
same outputs. The SLP cannot control an output that is being controlled by the CPU,
since the 90-30 CPU always takes precedence when both processors are controlling the
same outputs.

All of the outputs used in the State Logic program should be selected to be contiguous if
system response time is important. Outputs being non-contiguous causes the scan rate
to increase significantly .

When changing outputs the SLP writes to a byte of I/O bits at a time, so that any the SLP
actually controls eight ouputs at a time. Therefore, if some outputs of a byte are not
named in the SLP program, ECLiPS issuses a warning that the other outputs in that byte
are changed when the program executes.

slots between are empty the SLP cannot communicate with the CPU. The SLP must
be in the main rack with the CPU.

Inser ting the SLP

Follow these steps to insert the SLP into the Series 90-30 rack:

1. Power down the Series 90-30 PLC system

2. Locate the desired rack and slot.

3. Slide the 90-30 SLP completely into the slot.

4. Press down firmly to lock the module in place, but do not use excessive force.

5. Power up the PLC rack. The Status LED flashes during power -up diagnostics. The
LED comes on steady when the SLP is ready for operations.

Configuration

Use the Logicmaster 90-30 configuration software to add the SLP to the Series 90-30
I/O configuration. This software is used to describe the modules present in the PLC
racks. Rack and slot location and other features for each module are entered by com­pleting setup screens that describe the modules in a rack.

Figure 2-1.

From the main menu of the Logicmaster 90-30 configuration software, press I/O <F1>.
The screen displays a representation of the modules in a rack. To add an SLP to the con­figuration, highlight the desired slot, then press Other <F8> and then PCM <F1>.

Now press Zoom <F10> to view the current configuration. Press <Enter> to enter the
highlighted catalog number and display the PCM detail screen.

Now set the Configuration Mode to PCM CFG for the 90-30 SLP. First highlight the Con­fig Mode option and repeatedly press the <Tab> key until PCM CFG is displayed on the
screen. The serial ports are under program control and the parameters are initialized by
the State Logic Processor.

Now press the <Esc> key to save the configuration and return to the rack display. The
display should now show a PCM in the correct slot. Send the configuration to the PLC
CPU and the configuration is complete.

During program execution the CPU must be in run mode with the outputs enabled. Use
LM90-30 to set the status of the CPU before executing the State Logic program.

connection points to clear the SLP. Reconnect the battery, turn ON power again, and
reset the SLP.

4. Check that the CPU is functioning properly by checking its “OK” LED.

5. Check that there are no empty slots between the CPU and the SLP. If there are
empty slots, the Status LED blinks continuously.

6. If the Status LED is still not ON, try to download a program from ECLiPS or OnTOP.
If you can connect with the SLP and download a program, then the Status LED is
faulty.

7. If you get a message that ECLiPS or OnTOP cannot connect to the controller, then
check the fault table in the CPU using Logicmaster 90. If there is a fault “Bad or
missing module”, then the SLP is faulty and must be returned for repairs.

8. If there is no fault then contact the GE Fanuc Hotline for assistance.

Serial Communication Problems

This section is split into two parts, communication problems to ECLiPS or OnTOP and
problems with other serial devices.

GFK-0726B

3-1

Communications Problems with ECLiPS or OnTOP

1. Check that the serial cable used conforms to one of the types specified for
communications to the SLP ports. Check that the cable is firmly secured at both
ends.

2. When there is a communications problem, a message indicating problems
connecting to the controller is displayed together with some options. Select the
“Change Host Comm Port Settings” option to check the computer port being used
and the baud rate. The default SLP baud rate is 19.2K.

3. The SLP programming port may have been changed. ECLiPS and OnTOP must be
connected to the designated programming port. The default programming port is
Port 1 but can be changed by ECLiPS or OnTOP. Make sure the serial cable is
connected to the current programming port.

4. The SLP serial port configuration may have been changed. These parameters can
only be changed by Statements using the Set_Commport keyword in the State Logic
program. Reset the SLP to return the SLP serial port parameters to their default
state. If the program is setup to start running automatically and the program
continues to change the serial port parameters after the reset switch is pressed, turn
off the power to the SLP, remove the batter y, and short the SLP battery leads to reset
the SLP.

5. Port 2 of the 90-30 SLP is an RS-422/485 port and Port 1 is an RS-232 port. Make sure
that the host computer serial port setup matches the SLP port for RS-232-RS-422/485
option.

6. If there is still no communication between the SLP and OnTOP or ECLiPS then call
the GE Fanuc Hotline for assistance.

Communications Problems with Another Serial Device

1. Check that the serial cable used conforms to one of the types specified for
communications to the SLP ports. Check that the cable is firmly secured at both
ends.

2. Make sure that the serial port parameters of the serial device match the settings of
the SLP. The default settings of the SLP are 19.2K baud rate, 8 data bits, 2 stop bits,
and no parity.

3. Make sure the RS-422/485-RS-232 standards are the same for SLP and the serial
device

4. When connecting some device to the programming port, make sure that you exit
ECLiPS or OnTOP normally before disconnecting from the SLP.

5. If there are still problems contact the GE Fanuc Hotline for assistance.

Chapter 4 Serial Communications

section level 1 1

4

Serial communications with the State Logic Processor (SLP) is provided through one of
the two serial ports. Each of these ports can send and receive serial data independent
from the other . Port 1 is an RS-232 port and port 2 is an RS-422/485 port. There is only
one 25-pin connector on the SLP which provides access to the connections for both
ports. The SLP comes with a WYE cable which provides one 25-pin connector for each
port.

ECLiPS and OnTOP must communicate with the SLP through the programming port.
Either port can be the programming port, but port 1 is the default programming port.
When ECLiPS or OnTOP is not connected to the SLP, the programming port can be used
to communicate with some other serial device. To properly set the programming port to
communicate with another device, exit ECLiPS or OnTOP normally before disconnect­ing from the SLP.

Either of these ports may also be a CCM port. The CCM port uses the GE Fanuc CCM2
protocol for all communications. This protocol is used for connecting the SLP with a host
computer which collects data and changes data in the SLP. Typical CCM uses are con­necting to a graphical user interface program such as CIMPLICITYr or for custom host
interaction with the SLP.

figure bi level 1
table_big level 1

GFK-0726B

The SLP is always a slave to the host, i.e., all communications are initiated by the host
computer. The SLP may be one of several devices on a CCM network. The CCM port is
always the port that is not designated as the programming port. The CCM port is a nor­mal RS-232 or RS-422/485 port when CCM communications are not enabled.

Programming Serial Communications

The program communicates through two ports using WRITE and READ terms. For ex­ample:

State: Get_Setpoint

Write “Enter New Setpoint” to Operator_Panel.
Read SetPoint1 from Operator_Panel, then go to Check_Setpoint State.

The Write Term sends the string of characters, Enter New Setpoint, to the port defined as
the Operator_Panel. This same port is then monitored for input by the Read Term in the
next Statement. The variable Setpoint1 is set to the value entered through the specified
port.

In this example the WRITE and READ term information is directed to a particular port.
Operator_Panel in this case is defined in ECLiPS as Port 1 or P ort 2. Use the ECLiPS, DE­FINE or LIST menus to make the port definitions. The default names are Port_1 and
Port_2.

The Read and W rite Terms may also be used without being directed to any particular
channel, for example:

State: Choose_Recipe

Write “Enter Recipe Number”.
Read Recipe_Number, then go to StartBatch State.

Since no port is specified in this example, information is sent to the programming port.
For a more detailed discussion of programming serial input and output, refer to the Ref­erence Section of the ECLiPS User’s Manual.

Serial Port Setup

There are several serial port configuration options. Some of these options are set using
ECLiPS or OnTOP, and others can only be set by an executing State Logic program.

ECLiPS or OnTOP Options

The options available in the ECLiPS or OnTOP menus to change the configuration of the
SLP serial ports are displayed below .

The options available in the ECLiPS or OnTOP menus to change the configuration of the
SLP serial ports are displayed below .

Change Programming Port

Enable/Disable CCM Port
Set CCM Station Number

Set the RSĆ422/485 Status of each Port

Serial Options Set by ECLiPS or OnTOP

Each of these options is set in the State Engine Configuration Menu selected from the
Debug Mode Project Menu in ECLiPS or from the Controller Option in OnTOP.

Programmable Setup Options

On power up the serial port parameters are set to their default settings. These settings
may be changed by using the Set_Commport programming keyword in the control pro­gram. The Set_Commport keyword and parameters must be executed by the control
program to change the serial port settings. Just changing the parameters in the ECLiPS
serial communications setup form does not automatically change these settings.

After the SLP serial port parameters are set, ECLiPS automatically enters the Set_Comm­port instruction into the program when the following selections are made. Select the
LIST option from the program mode menu; then select the Communication Ports option.
Highlight the appropriate port and press <Enter>. ECLiPS prompts whether to enter
the port name only or enter reconfiguration data. After selecting Enter Reconfiguration
Data, the Set_Commport keyword plus the instructions to change the serial port param­eters are entered into the ECLiPS program.

These options affect the SLP serial port configuration only, not the ECLiPS or OnTOP
serial port setup. The option to change the ECLiPS or OnTOP host computer serial port
configuration is available only when there is some problem connecting ECLiPS or On­TOP to the SLP. The only options which can be changed on the ECLiPS or OnTOP serial
port configuration are selecting COM1 or COM2 and changing the baud rate.

Serial Cable

The State Logic Processor (SLP) is designed to work with two GE Fanuc standard serial
cables. One cable is the Mini Converter Kit that comes with the ECLiPS. The other is the
PCM to IBM-PC cable. Use the RS-422/485 serial cables to connect to P ort 2, if
RS-422/485 communications are used.

Mini Converter Kit

ECLiPS comes with a serial cable kit that can be used to both connect the CPU with Lo­gicmaster and to connect the SLP with ECLiPS or OnTOP running on an IBM PC. This
cable kit comes with three adapters:

9-pin Male to 25-pin Male SLP Ports 1 or 2 AD232/1-2
9-pin Male to 25-pin Female IBM PC COM 2 HE 693XTADP

The cable provided in the kit is terminated with two 9-pin connectors. One of the adapt­ers connects the 9-pin serial cable to the 15-pin serial port on the CPU (HE693SNP232),
another adapter connects the serial cable to the 25-pin female Port 1 on the SLP
(AD232/1-2), and the third adapter can be used to connect to a 25-pin port on the IBM
computer running Logicmaster 90, ECLiPS, or OnTOP (HE693XTADP).

Custom Made Cables

If you want to make your own cable to connect to some serial device, use the drawing of
the SLP pin assignments and the cable connection drawings in the previous section for
the required connections. Hardware flow control lines must be used when communicat­ing with the SLP using RS-232. The flow control lines are not used for RS-422/485 com­munications.
