BR-Bit (BInary-Result)

This bit is used to analyze the ENO-output of functions, function blocks and MOVE-blocks, for example.

You can copy the RLO into the BR-bit by the instruction SAVE.

You can use the BR as operand for A, O, AN, ON, ... . With the conditional jumps JBI and JNBI you can also evalutate the BR-bit. With the jumps JCB and JNB the RLO is copied automatically into the BR-bit.

If you write a function or a function block whose ENO-output is analysed in the calling block you will have to set the BR-Bit correspondingly in the last network of the FC or the FB with the instruction SAVE. For this you can set the RLO correspondingly with SET or CLR before.
