Analog I/O scale
I am using an eCo PM564T PLC with codesys software V2.3 and have a problem to scale the on-board AI/O.
I am reading an Anlog signal from a flow meter and pressure transmitter (4mA-20mA or 0V-10Vdc) and want to display the readings on my visualization window using meter tool.
Can any one assist me on that please.
AC500 PLCs analog input cards return to user up to 32767 value as an integer. As 4-20mA selection 0 integer value equals to 4mA, and 32767 integer value equals to 20mA. (Same as 0-10V selection)
So at first you have to create a Scale block according to analog ranges.
