1. folder The reason for this suggested procedure is that loading the State Engine from the folder on the floppy drive is quite a bit slower than loading it from a folder on the hard drive Loading the State Engine from the floppy disk works properly but is slower New Features and Functionality The State Engine has been modified to support the CPU925 CPU module Problems Resolved by This Upgrade Lights out with No Faults or PLC CPU Hardware Fault with Programmer Access Due to component timing tolerances and large ladder programs with certain sequences SNP programmer port activity could have caused the CPU to suspend execution until a hardware watchdog timeout reset the board or a PLC CPU Hardware Fault occurred Changes in the hardware were made to avoid the race condition that allowed the fault to occur 6 Important Product Information State Logic CPU Module February 13 1997 GFK 1042G Restrictions and Open Problems 1 Automatic Program Execution There is a remote possibility that retentive data in the controller can become corrupted during a power cycle If there are any variables set to be retentive or any Task is set to restart in the State that was last active using the Start_In_Last_State keyword the controller checks for that corruption possibility on power up If the controller detects that there has been some corruption the controller does not start the program running sends a message to be displayed by ECLiPS and clea2. kit will update any number of CSE924 CPUs to Release 6 02 firmware Documentation The following table lists the applicable documentation for the IC697CSE924 CPU Table 6 User Documentation 1C697CSE924 ED GFK 1036Aor later Important Product Information State Logic CPU Module GFK 1042G February 13 1997 Full Documentation Sets Full documentation sets are also available in either printed bound form or in electronic form CD ROM Please refer to the following table for ordering information for full documentation sets Table 7 Full Documentation Set 1C697LBR701 Paperlibrary full set of printed manuals IC690CDRO02 CD ROM full set of manuals in electronic format Current version Read this document before installing or attempting to use the IC697CSE924 State Logic CPU Module For more information refer to the applicable Programmable Controller Installation manual Programming Software User s Manual Programmable Controller Reference Manual and State Logic Control System User s Manual Special Operation Notes For State Logic Operating System Version 1 09 1 Storing a New Folder Whenever the IC641 programming software program folder is stored from the programmer to the controller in stop mode the State Logic program must also be downloaded again using the ECLiPS program development software The reason that the State Logic program must be downloaded again is that the memory location for the State Logi

4. ISABLE mode The LED is OFF when the CPU is in STOP mode The CPU must be put into run mode using C641 programming software ECLiPS cannot communicate with the State Logic CPU if the CPU is in STOP mode Bottom LED Enabled The bottom LED labeled ENABLED indicates the state of the outputs The LED is ON when the outputs are enabled and the State Logic Program is running The LED is OFF when the outputs are disabled NOTE The CPU will not go into RUN ENABLED mode using IC641 programming software Attempting to place the program into RUN ENABLED mode from IC641 programming software will place the CPU into RUN DISABLED mode In order to enter RUN ENABLED mode the CPU must be loaded with a State Logic Program and the program must be running ECLiPS programming software is used to create load and run the State Logic Programs 6 Run Enable Disable Switch Asmall switch is located beneath the operation LEDs on the State Logic CPU the switch can be used to control the Run Status of the CPU The switch has positions that control the Run Status Up for Run Enabled Middle for Run Disabled and Down for Stop Important Product Information State Logic CPU Module GFK 1042G February 13 1997 The switch overrides the Run Status set by IC641 programming software or ECLiPS If the switch is moved to the down position the State Logic program and any other programs in the CPU stop execution and outputs are disabled If the switch is then moved
