Siemens 505-2557 User Manual

Advanced Function Programming

First turn on the base power supply. If the module diagnostics detect no
problems, the status indicator on the front of the module will light. If the
status indicator does not light, blinks (or goes out during operation), the
module has detected a failure. For information on viewing failed module
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.

FUNCTION

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.
