Logging the	First turn on the base power supply. If the module diagnostics detect no
Module in the	problems, the status indicator on the front of the module will light. If the
Controller I/O	status indicator does not light, blinks (or goes out during operation), the
Configuration	module has detected a failure. For information on viewing failed module
Memory	status, refer to your SIMATIC 505 TISOFT2 User Manual
	(PPX:TS505±8101±x). To diagnose and correct a module failure, refer to the
	section on troubleshooting.
	You must also check that the module is configured in the controller memory.
	This is important because the module will appear to be functioning
	regardless of whether it is communicating with the controller. To view the
	controller memory configuration chart listing all slots on the base and the
	inputs or outputs associated with each slot, refer to your SIMATIC 505
	TISOFT2 User Manual. An example chart is shown in Figure 3-2. When the
	module is properly logged in to the controller as a high-density discrete and
	analog module the configuration is 16X, 16Y, 32WX, and 32WY registers.

Figure 3-2 SIMATIC 505±2557 I/O Configuration Chart

In this example, the module is inserted in slot 1 in I/O base 0. The first X point is assigned the first I/O address. In this example, the I/O assignments are: X1 . . X16, Y17 . . Y32, WX33 . . WX64, WY65 . . WY96. For your particular module, look in the chart for the number corresponding to the slot occupied by the module. If word memory and discrete locations appear on this line, then the module is registered in the controller memory and the module is ready for operation.

If the line is blank or erroneous, re-check the module to ensure that it is firmly seated in the slots. Generate the controller memory configuration chart again. If the line is still incorrect, contact your local distributor or Siemens Energy & Automation, Inc., Technical Services Group.
