Installation

First turn on the base supply power. 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 TISOFT or SoftShop user manual.
To diagnose and correct a module failure, refer to the next section on
troubleshooting.

You must also check that the module is configured in the memory of the
PLC. This is important because the module will appear to be functioning
regardless of whether it is communicating with the PLC. To view the PLC
memory configuration chart listing all slots on the base and the inputs or
outputs associated with each slot, refer to your SIMATIC or TISOFT
Programming Manual.  An example chart is shown in the following figure.

In this example, the SIMATIC 505–2557 Module is inserted in slot 1 in I/O
base 0.  Data for channel 1 appears in word location WX1, data for channel
2 appears in word location WX2, etc. For your particular module, look in the
chart for the number corresponding to the slot occupied by the module. If
word memory locations appear on this line, then the module is registered in
the PLC 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 PLC memory configuration chart
again. If the line is still incorrect, contact your Siemens Energy &
Automation, Inc., distributor or sales office. 

NOTE:  In advanced Operating Mode the module logs in to the PLC as 16X,
16Y, 32WX and 32WY.
