fm354 module interfacing with cpu s7-315

Dear sir,

For our machine we are using fm354 module for position control CPU s7 315  . As per   fm354 manual we are made program which one is attached for your reference

We used fc0 , fc1, fc2, fc3 OB1, OB100,OB86,OB40, and  UDT , we are using fm354 for first time . we are not able to get reading from attached program . we are very much

thankful to if you give feedback where have gone wrong.

We have faced following problems while using above program.

1.       While calling  FC1 cyclic in OB1 main CPU get in error mode or some time all the digital output start flickering.

2.       We are able to read linear scale pulses in hardware diagnostic mode while  CPU in stop mode but not able to read from UDT AW-DB block.

3.       Also not able to give -10v to 10v command from this module.

Please suggest how to solve the problem

 Hi, 

No worries. Please upload the diagnostic buffer, so we can have a look what is happening. 

sir,

i am uploading the diagnostics buffer of fm354 module in which external error is showing.

In attach file error is showing external error .

sir,

While calling  FC1 cyclic in OB1 main CPU get in error mode or some time all the digital output start flickering.

now i have bypassed  calling fc1 then now plc in run mode no error in cpu but not getting reading in db50 and analog output +-10v in same db block.

please check attached program.zip and tell us where we have gone wrong and we are very much thankfull  for extending your whole hearted support.

 Hi, 

]I do not have all the SW components installed on my PC to analize your SW. BY the way if you go online with your PLC and under "CPU/Modul Information" you  can choose the Diagnostic buffer. The content of the buffer can be saved to text file.

From that information we can see what is actually going  wrong with your program.

Please attach the buffer so we can have a look.
