All-knowing list, I have FCS 5.0 (Archestra IDE) and I would like to do some logic with more than 24 boolean inputs (valve & motor statuses). I cannot seem to figure out how to use COMPOUND:BLOCK.PARAM.EXT in HLBL, specifically the IND block. For instance, I can define a bool under VARIABLES: BOOL_VAR : B; And assign an external reference to it in my STATEMENTS: BOOL_VAR := COMPND.PAKIN_BLK.PAKCIN.B4; The block compiles with this syntax, but IDE shows the block with OP_ERR="-60", which B0400DF describes "param does not exist... the full pathname refers to a block that exists in the control database, but the parameter with given name does not exist in the block". The IND block is held in manual and doesn't do anything. Other familiar IDE syntax like "COMPND.PAKIN_BLK.PAKCIN#B4" refuses to compile. Any thoughts?
