Need some help with a conversion I'm doing from a micrologix 1500 to compact L30E. The program is using indirect addressing with latches and bit function, I'm a little new with indirect direct addressing used in this matter and could use a smart person to help me understand it . What I have is several instructions like this whether it is a bit or a latch instruction -l l- B203:0[N201:0] I need help converting them. The new tags for this illustration I created -l l- AXIS_HOME[MOTOR_OFFSET] . But I get an error invalid array subscript specified. Thanks!
