Hello,
I have Lookout 6.1 and I want to communicate with a Hitachi PLC model EH-150. I chose lookout because I read that there is a driver for the PLC and I guess it kinda work but not really since I'm new to this software. I looked at several tutorials and tried to figure things out based on other PLC models but couldn't. Also there weren't any tutorials for Hitachi PLC.
So basically I'm just trying to get pressure and temperature readings from the Hitachi PLC. I opened up Lookout, created a new process in lookout, created a new object and selected Driver > Hitachi_EH150. I have the CPU EH-CPU104 so I configured it to connect via the RS232 cable that I made going to the PLC and everything were set correctly. (COM1, 19200, 7, N, 1) . I then used object explorer and expanded to Process1 > HitachiE1 > Y0-Y4FF95, I selected this and drag it on to the control panel. It displays 0 and then an error comes up in the alarm windows that says "HitachiE error message: Type code of I/O is undefined or Requested I/O is out of valid range". Is the error because I'm trying to read from the wrong memory address? Is there anyway to figure out where the data is stored? How do I make it so that I can retrieve the pressure readouts from the PLC?

I have attached the lookout process file here and the manual for EH-150 can be found at http://www.softstartuk.com/downloads/manuals/eh-150-manual.pdf
