Gents: I have a S7 315-2 DP PLC with several IM153-1 Racks. I have 4 Siwarex U Weighing Modules in one of the remote racks. I am using a SFC 58 to read information from the Weigh Module. I have setup a load cell and programmed the module with Siwatool and I can see weight through the Siwatool. I have a Wonderware operator interface that I am trying to read this weight into. Please see the following configuration for the SFC 58. IOID= B#16#54, Laddr= W#16#110, RecNum= B#16#1F, Output DB14.DBW0. I am reading Data Record 31.
Now, when I try to see the data in DB14.DB0 and DB1, I don't see any data. The SFC doesn't have any particular error code.
I am trying to understand why I can't view data at DB14.DB0. The manual states that Gross Weight is in Byte 0,1 in INT format. In DB14, I made an array of 0-9 Bytes.
Also, I am going to have to build a calibration screen in the Wonderware Operator Interface. What do I need to include on the Calibration Screen? What type of alarms do I need that are typical.
This is my first Siwarex U job and I would appreciate the help..
Thanks,
