A0845A 3BSE045584R1 processor module

If both the FCs 215 and 216 have the wrong address, the controller status will indicate a local I/O error. To correct this: 1. Remove the ASI module and change the setting of S1 to match the controller configuration settings. 2. Refer to Section 3 for information on setting an address and installing an ASI module.

This section shows the pin connections for the IMASI13 module. The analog input module has three connection points for external signals and power (P1, P2 and P3). Table 6-3 shows the pin connections for P1. Table 6-4 shows the pin connections for P2. Table 6-5 shows the pin connections for P3.

I/O Expander Bus Interface Test

 The I/O expander bus test checks for proper operation of the following interface components. • I/O expander bus interface. • Dual-port static RAM (ASI module read/writes and controller read/writes). • Controller and ASI module handshaking. Perform the following steps to check I/O expander bus interface operation: 1. Tune specification S1 of FC 217 to 10 indicating I/O expander bus test. Also, tune specification S2 to the block address of the ASI module's FC 215. Set all other specifications to the default value and send this block. 2. Monitor FC 217, output N+4 to determine the status of the I/O expander bus. If block N+4 is 0000, the test is successful. If block N+4 is 2000, the test has failed (data passed back was incorrect).For more information on FC 217 errors, refer to the Function Code Application Manual. The functional test is complete. If the IMASI13 module does not function properly, return it for repair.

The reliability of any stand-alone product 

or control system is affected by the maintenance of the equipment. ABB Automation recommends that all equipment users practice a preventive maintenance program that will keep the equipment operating at an optimum level. This section presents procedures that the customer should be able to perform on site. These preventive maintenance procedures should be used as a guideline to assist in establishing good preventive maintenance practices.
