HI Kyle,

Take a look at table 6.1 – 6.5. I want to pull word [1] – [13] and then parse words [16] – [19] per the bit index in tables 6.2-6.5. I will be back in 30 to have another go at it.

Thanks for your help!




Hi Kyle,

Were you ever able to look at the documentation I provided and come up with an answer as to why I am not getting the data values? I can be reached on my cell at (562)673-9793.



Hey Mike,

I’m sorry I didn’t get a chance to talk to you today. I did look at the instructions and I think the problem is that the Command triggers aren’t being triggered by the PLC. Can you send me a log and let me know when you are available tomorrow and we’ll try to get this figured out?



Hi Kyle,

Today is not a good day for me. I will call tomorrow around 8 AM PST.

Thanks again!


Sounds good Mike. I’ll talk to you then.
