Advanced Function Programming

Use the following procedures and Table 3-10 to troubleshoot your system.

•

First examine your V- or K-memory tables to ensure that the data to be
loaded into the module makes sense.

•

Utilize the worksheets located at the end of this chapter to calculate
key address locations.

•

Examine the relay ladder program to verify that the V-memory tables
are being loaded into the correct WY65 – WY96 output registers.

•

Examine the starting address of the module and ensure that the offsets
for the X16 input Module_Ready = (starting address + 15) and that the
Y outputs = (starting address + 16), that the WX registers = (starting
address + 32) and the WY registers = (starting address + 64).

•

Examine the relay ladder program to verify that the addresses used
match the offsets as described above and those from the worksheets.

•

Verify that the data identification outputs Y19 – Y17 properly reference
the data that is being loaded.

•

Use the TISOFT status and chart functions to debug the program and
to verify that the X16 Module_Ready input does indeed turn on. If this
input does not turn on, there is a problem with the module. Contact the
Siemens Energy & Automation, Inc., Technical Services Group.

•

Verify that the Y32 Data_Ready output does indeed turn on to load the
data into the SIMATIC 505–2557 module.

•

Place a known input value on the module channel and verify that the
channel is producing the correct results.
