1 Physical Description The SLP occupies a single slot in the Series 90-30 rack, communicating with the PLC CPU over the backplane to perform its many control functions. The SLP controls and accesses CPUI/O, register, and system data. a45085 ÎÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎ Î ÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎÎÎ ÎÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎÎ Î ÎÎ ÎÎ Î ÎÎ ÎÎ ÎÎ Î ÎÎ ÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎÎÎÎÎ Î LOCAL RACK CONFIGURATION P S C S P L U P Figure 1-1.

Series 90-30 State Logic Processor The SLP comes with a battery to maintain memory when power is removed. This is a lithium battery which is installed as shown in the SLP drawings. When the battery reaches a low charge, this condition is reported to the PLC fault table.
1 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.
Chapter 2 Installation and Maintenance 2 section level 1 1 figure bi level 1 table_big level 1 This chapter describes how to install the SLP into a Series 90-30 PLC rack. There is also a section describing maintenance considerations. Selecting the Right Slot The SLP can be installed in any unused slot in the CPU rack of the Series 90-30 PLC if the following rules are followed: 1. Configuration created by Logicmaster must match the physical location of the modules.
2 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. Sample Logicmaster Configuration Screen From the main menu of the Logicmaster 90-30 configuration software, press I/O .
2 Battery The State Logic Processor comes with a 3 volt lithium battery (IC697ACC701) to maintain memory through a power cycle. If the battery charge becomes low, a fault is set in the fault table. These faults can be monitored by the State Logic program. To replace the battery, connect the new battery to the extra set of battery connections then disconnect the old battery. A Product Safety Data Sheet for the battery is available. Order from GE Fanuc using number GFK-0633.
Chapter 3 Troubleshooting 3 section level 1 1 figure bi level 1 table_big level 1 This chapter provides procedures for diagnosing State Logic Processor (SLP) problems. If these procedures do not solve the problem, contact the GE Fanuc Hotline (1-800-828-5747) for assistance. Status LED is not ON Steady 1. Check that power is supplied to the I/O rack housing the SLP. Try removing and reinstalling the SLP. 2. Cycle power to the SLP, then press the reset button for more than 5 seconds. 3.
3 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.
Chapter 4 4 Serial Communications section level 1 1 figure bi level 1 table_big level 1 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.
4 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.
4 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.

4 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 Port 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.
4 Other Cable Options Other cables that work with the SLP are the IBM-AT cable, IC697CBL702, and the Workmaster II or PS/2 cable, IC697CBL705. The connector on the SLP end can be made to be a right angle connector, so that the SLP front cover can be closed and the cable brought out the side of the SLP or through the bottom of the Series 90- a42832 30 chassis.
4 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.
