Fast counter integrated in S500 modules
The following table shows the S500 modules which contain a fast counter and which of the digital inputs and outputs are reserved for the counter.

The fast counter of an IO module can only be used when the module is connected to a IO-Bus master (CPU or Interface module) which supports fast counter on the attached IO modules |

1) The two hardware inputs (channels A and B) are also and always available within the normal process image, irrespective of the operating mode of the counter.
2) The hardware output channel C is activated by the fast counter only in the operating modes 1 and 2.
3) Especially for module DA502: The counter operating mode 101 is the same as mode 1, but the assigned output is DO0 instead of DC18. Also the counter operating mode 102 is the same as mode 2, but the assigned output is DO0 instead of DC18.
