Although there are many possible detailed conditions which can cause the module to fault they all come down to the fact that the main micro on the DEM has failed to communicate with one or both of the DE Communication processors Normally this condition is indicative of a hardware problem possibly a failure but it may also indicate that the DE CPU failed due to erroneous data being received either from the SLC or from the instrument 20 Hardware Diagnostics amp Troubleshooting 6 2 1 6 2 2 6 2 3 6 3 6 4 Although the exact cause of the fault condition should be determined from the Module Status value in the data table the LEDs on the front of the module will also indicate some status DE Init Error ACTIVE FLT The module is in a faulted condition This indicates that COM OO ERR the main CPU on the DEM has failed to communicate with the DE processor DE Reset Error ACTIVE FLT The module is in a faulted condition This indicates that COM OO ERR the 6811 DE CPU processors has failed to Reset properly during initialization Try resetting the module again Call the Factory if all else fails DE Timeout Error ACTIVE FLT The module is in a faulted condition This indicates that COM O ERR the 6811 DE CPU processor has not returned control of the Shared RAM in the proper timeframe Try resetting the module Call the factory if all else fails Clearing a Fault Condition To clear a fault condition verif

25. C Floating Point table is easily accomplished through some simple ladder logic programming The programming necessary to move the Floating Point data to from the module takes advantage of the COP command that exists in the PLC and the SLC The COP command is unique in the SLC data movement commands in that it is an untyped function meaning that no data conversion is done when moving data between file types i e itis an image copy not a value copy The structure of the COP command to move data from a Floating Point file into the MO File something you would do to move floating point values to the module is as follows COP SRC 3 F8 0 DEST MO 1 90 COUNT 2 This command will move one floating point value in two 16 bit integer images to the integer file For multiple floating point values simply increase the count field by a factor of 2 per floating point value The structure of the COP command to move data from an Integer file or Input File to a Floating Point file something you would do to receive floating point values from the module is as follows This command will move two 16 bit integer registers containing one floating point value image to the floating point file For multiple values simply increase the count field 12 Reading Data from the Module Input M1 Files 4 3 4 3 1 4 3 2 Reading the M1 File The File is a data file that contains the results of the instrument database reads perf
