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. The SLP cannot control an output that is being controlled by the CPU, since the 90-30 CPU always takes precedenc

Chapter 2 Installation and Maintenance section level 1 1 figure bi level 1 2 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. Configuration faults ar

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 com- pleting 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 . The screen displays a representa

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. GFK-0726B Chapter 2

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

Chapter 4 Serial Communications section level 1 1 figure bi level 1 4 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. The SLP comes with a WYE cable which provides one

4 Programming Serial Communications The program communicates through two ports using WRITE and READ terms. For ex- ample: 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 ente

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.
