Function
The input signals of this function block are copied to the 8-byte user data of the CAN object 1 and
assigned to the system bus. The meaning of the user data can be determined very easily with
C0864/1 and C0865/1 and the corresponding configuration code (CFG).
Byte 1 and 2
Here, the status word from the function block STAT is mapped.
(E 7-266)
Some of the bits are freely assignable.
Byte 3 and 4
Here, the analog signal configured at the CAN-OUT1.W1 input is mapped.
Byte 5, 6, 7, and 8
The meaning of these user data can be selected among different signal types. According to the
requirement up to two analog signals, 32 digital signals from the function block FDO or one phase
signal can be selected. Mixes forms are also possible.
Example:
16 digital signals and one analog signal are to be output.
The digital signals are output via the FDO function block. Here, the bits 16 to 31 are to be output. For
this purpose set C0865/1 = 1. The bits are output on byte 7 and 8.
It follows that the analog signal is led via CAN-OUT1.W2. For this purpose set C0864/1 = 0. It is output
on byte 5 and 6. The input is assigned to an analog signal source via configuration code C0860/2.
