* Note: Operation Analysis means that D2000 KOM can analyze the message and assign values to the appropriate I/O tag. For example, for a Binary Input Event (2) group, values are assigned to the I/O tags from the Binary Input (1) group.Kotva poz* poz*

Note: D2000 KOM supports sending a message with the writing type outside the range allowed by the standard - e.g. for the Analog Output (41) group, a write operation with Write (2) function can be configured.
