7. PLC Fault Table or other unexpected behavior Serial Load Store of Register Table Causes Ethernet Programmers to Lose Communication A load or store of the PLC Register YR table by a PLC Programmer connected through the CPU serial port can cause Ethernet applications that use the PLC programmer communication window to lose communication This condition occurs when the load store operation requires more than 10 seconds to complete For example transferring the R table of a CPU341 or CPU351 at 19 200 baud or less will cause the timeout The Ethernet Interface posts two or more PLC faults with the text LAN system software fault resuming and fault specific data starting with 080008 and or 080042 In addition faults with text Bad remote application request discarded request 1B0021 and Local request to send rejected discarded request 110005 may occur The STAT LED on the Ethernet Interface goes out IC693 MS DOS TCP IP Software Briefly Loses Communication When Configuration Cleared or Stored Clearing or storing the PLC configuration causes the MS DOS Ethernet programming software to display a flashing NO COMMUNICATIONS message for one or two seconds PLC faults similar to those listed under Serial Load Store of Register Table Causes Ethernet Programmers to Lose Communication above occur the STAT LED on the Ethernet Interface goes out In some cases a ten second delay occurs before loss of communication is detected

9. els Data Transfer Entering STOP IOSCAN Mode Use caution when configuring the PLC CPU to scan I O in STOP mode There is a small time delay between a RUN to STOP IOSCAN mode transition in the PLC CPU and the time when the Ethernet Interface deactivates repeating channels The length of this delay varies with the PLC hardware configuration and the application program In some cases the time delay will be long enough that one data transfer by a repeating channel will occur after the CPU mode transition After a RUN to STOP NO IO mode transition the Ethernet Interface aborts repeating channels immediately RUN Mode Program Store A store of a folder containing large greater than 14kb program blocks using a PLC Programmer via Ethernet may fail and result in momentary loss of communication This condition has been observed only when attempting to store a large program to a PLC which is in RUN mode and which is configured to use a limited communication window These conditions cause the store operation to take the maximum possible period to complete The failure may occur if this period exceeds 10 seconds for an individual program block If this problem does occur one of the following options may be used to complete the store operation successfully 1 Change the PLC configuration to use Run to Completion mode instead of a Limited Communication Window for the store operation 2 Change the PLC from RUN to STOP mode to complete the store 3 Struct
