I need to read 44 analog inputs 4-20mA by adresses 512 to 607 INPUTS WORDs of Siemens PLC S7-300 CPU-315 2DP with STEP 7 V5.4. I need to convert this analog signal's to 0-100% value in scale block. But when I load the block in the ladder program, the variable's LOW limit and HIGH limit doesn't show in the network rung. What I can do to solve this problem?

Many thanks
