TROUBLESHOOTINGMODULE FUNCTIONAL TESTS6 - 6 I-E96-301B®Error ExampleFunction code 215 for the slave and 216 for the active channelneed the same address. Check that the address on IMASI03switch SW1, the address in function code 215 specification 1and function code 216 specification 1 are the same.If function code 216 slave address is not the same as functioncode 215 the MFP will go into error mode when put into exe-cute mode. The error will indicate 5, (byte 3 of module sta-tus/error message = 05) Configuration Error - UndefinedInput.Modify the address in function code 215 and the associated216 blocks. The IMASI03 address value set in function code215 specification 1 and function code 216 specification 1should match the slave address set on SW1 on the IMASI03module.Use an INFI 90 operator interface to change the configurationdata. For procedures on how to change a function code specifi-cation, refer to the product instruction manual for the operatorinterface being used.The master module generates a local I/O error in the modulestatus if the slave expander bus is not connected between theslave module and the master module. Verify that the bus isconnected on the MMU backplane.NOTE: Setting FC 215 specification 4 to 0 will cause the mastermodule totrip when the IMASI03 module fails. Changing specifica-tion 4 to a 1 causes the master module tocontinue to operate if theIMASI03 fails or is missing.If both the 215 and 216 blocks have the wrong address, theMFP status will indicate a local I/O error. To correct this:Remove the slave module and change the setting of SW1 onthe IMASI03 to match the module configuration settings.Refer to Section 3 for information on setting an addressand installing a slave module.MODULE FUNCTIONAL TESTSThere are two sections in the slave functional test. Self-con-tained, dipswitch configurable diagnostics. Slave expander businterface testing (requires an MFP).Test Equipment RequirementsTo perform the functional testing, a single powered MMU slot(+5 V, ± 15 V, and power fail interrupt - PFI) is required.
