Suggestions
•
Macros cannot directly specify PLC addresses. Use READCMEM() to store the address at $W.
•
A numeral display and input object can be used to display word contents. Set the scale and offset
under
Unit & scale setting
to display an automatically scaled result without executing a macro opera-
tion.
•
Word contents can be judged because operators can use logical and comparative operands in addi-
tion to arithmetic operands.
•
If word lamp display is not required, change the settings to no display or move the word lamp outside
the screen.
