Description
---(SAVE) (Save RLO into BR Memory) saves the RLO to the BR bit of the status word. The first check
bit /FC is not reset. For this reason, the status of the BR bit is included in the AND logic operation in
the next network.
For the instruction "SAVE" (LAD, FBD, STL), the following applies and not the recommended use
specified in the manual and online help:
We do not recommend that you use SAVE and then check the BR bit in the same block or in
subordinate blocks, because the BR bit can be modified by many instructions occurring inbetween. It
is advisable to use the SAVE instruction before exiting a block, since the ENO output (= BR bit) is then
set to the value of the RLO bit and you can then check for errors in the block.
