SC540 3BSE006096R1 logic module card

For fault reporting when an analog expander is used in a Series 90-70 Expansion Rack, a special case exists when the ALG230 base module is in slot 2 and an expander module is present in slot 9. In this case, if any expander module loses communication with the base module, then the fault reports for all 16 channels for that expander display the slot number as 0. The circuit number will be a value from 9 to 120, as shown in the following table. The I/O reference address for each channel is displayed as blank.If the user stores a hardware configuration to flash which indicates that “Logic/Config Power up Source” is set to “Always Flash” or “Conditional Flash” and then subsequently changes the name of the target in the programming software, the hardware configuration will go Not Equal and will not Verify as equal.

Both Controller and IO fault tables need to be cleared to take the CPU out of Stop/Fault mode. If one of the tables contains a recurring fault, the order in which the tables are cleared may be significant. If the CPU is still in Stop/Fault mode after both tables are cleared, try clearing the fault tables again.

Logic and HWC not equal after power cycle

 If the Hardware Config from Target 1, with Logic/Configuration Powerup Source and Data Source both set to “Always from Flash,” is stored in Flash, then Logic and Hardware Config from Target 2, with Logic/Configuration Power-up Source both set to “Always from RAM,” is stored to RAM and there is a good battery, then when power is cycled the programmer may show that Logic and Hardware Config are not equal. The remedy is to clear Flash and then store the Logic and Hardware Config from Target 2.When using Version 5.8 of Proficy Machine Edition with any of the CRE redundancy CPU modules, Run-mode Stores are not possible when Machine Edition is connected to the RX7i through an IC698ETM001 Ethernet module when the CPU is running in Constant Sweep mode. The remedy is to connect Machine Edition to the controller through the CPU module’s Ethernet daughtercard.

WinLoader does not detect if a PC's COM port is already in use when attempting to connect to a PACSystems CPU to perform a firmware upgrade. If the port is already in use it displays the status "trying to connect" followed by "waiting for target." To proceed with the upgrade, press the "abort" button and disconnect the other application that is using the COM port

CPU Operational Notes

Multiple calls to SVC_REQ 57 (Logic Driven Write to Nonvolatile Storage) could result in the CPU tripping the watchdog timer and going to STOP-HALT mode. The number of calls to SVC_REQ 57 that can be made requires consideration of many variables, what the software watchdog timeout value is, how much data is being written, how long the sweep is, age of nonvolatile storage (flash), etc. If the application attempts to write to flash too frequently, the CPU could experience a watchdog timeout while waiting for a preceding write operation to complete. The Logic Driven Read/Write to Flash service requests are not intended for high frequency use. GE Intelligent Platforms recommends limiting the number of calls to SVC_REQ 57 to one call per sweep to avoid the potential of for causing a watchdog timeout and the resulting transition to Stop-Halt.

Prior to Release 6.71 for the RX7i, the Modbus RTU slave protocol would return an Invalid Function Code error response (1) upon receipt of a request with an invalid or undefined function code. Starting with Rel 6.71, the Modbus RTU slave ignores requests with an invalid or undefined function code, and no response is sent.
