4.4.21 Configurable status word
With this function single bit information with up to 16 parameters can be copied into a
common status word (
Z165.2–).
The following settings are possible for each status bit ("channel")
m Parameter number of source
m Bit number
m Logical bit
Via the parameter Z165.6– Latch the state of short-time bits of the parameter Z165.2–
is specified (OR function).
Furthermore adjacent bit pairs of the parameter Z165.2– can be combined with logic op-
erations. The structure of the operations is predefined (see ZFig. 121–).
The following boolean operators are available: AND, OR, XOR, NAND, NOR and XNOR.
The operation results can also be mapped to the configurable bits 14 and 15 of the
Z108.3– Status word 1 of the drive manager. Here the information is available with a de-
lay of 1 ms. This function is described in the parameters Z108.9– to Z108.12–.
NOTE!
The cycle time of function is 1 ms. States, which occur for a short time interval will not
be detected reliably by the configurable status word or the latch. The configurable
status word is generated at the end of task RT1. That means that all other operations
of this task have been processed.
