i am running an SST profibus scanner with a ControlLogix PLC. I have so many questions that i dont think i could discuss them all here.
my i/o, automatically setup by the scanner, looks like this
Local1:c
Local1:i
Local1:o
Local1:s
i changed the i/o from reading/writing Ints to reading/writing Dints (data[1] as int is now data[0], bits 16-32 as dint). do i also need to change the status also?
the PB scanner setup looks like this in rslogix 5000:
assembly
instance
input 1 125
ouput 2 124
config 3 0
statusin 5 125
statusout 6
also, i am doing what is called 'paging' for my data. the sst scanner has 125 dwords in and 124 out. my program copies the data from the scanner to the appropriate page of data in a dint[500] array.
my data coming in is being copied to every page until it is overwritten by a new device on the same page offset. ex, a device on the 3rd dword of page 1 will get written to the 3rd dword of pages 2-4 if there is no device on that page.
and any tips on profibus to clx would be appreciated. thanks.
Why put it in the Siemens section?
I've done several CLX systems with the SST profibus module communicating to ABB drives and some encoders and load cells.
I have always followed the SST instructions and set the module for INT's and default sizes.
They work with no problems.
I don't understand your description of what you're doing.
What are you communicating with?
