The Industrial Raspberry Pi Forum

Hello,

I have questions regarding Profibus and general question about PLC.

1) We would like to use the profibus gateway in multiple different projects.
The best method that we found is by sending all the profibus memory/storage to our computer. But the most important thing for us, is to know what is being sent by the PLC (eg: Siemens s7).
For example we would like to know what kind of data type is being sent by the plc. Is it an int, float or words. Therefore we could then determine how to read the memory that we received at our computer.
Is there anyway for me to know what is the data type(eg: float, int, bit, byte) being send by PLC to the RevPi?

2) Can we configure a plc with the RevPi?

Thank you for your help.

Hi Miki, all the RevPi Gates have byte access in the little endian format. So you have to interpret the data. The RevPi Gates are all slave modules so it is not possible to configure a plc.

Thank you for your reply.
