Most of my lunch hour today has been spent searching the forum for help with this issue. While I did get some help from the various topics I still am not clear on some things.
First of all, I have not messed with a PLC5 in almost 15 years. We have primarily used SLCs on our systems. I would not be using a PLC5 at all except for the fact that the customer insisted on it.
Anyway here is my setup and questions.
12 Slot Chassis
1785-L30B Series E Processor
(2)1771-IFE/C Analog modules configured for single-ended current and located in slots 1 and 2 of the chassis.
I am using 1-slot addressing.
I also have 2 1771-IAD and 2 1771-OAD modules but I'm not concerned about them right now.
I allowed RSLogix5 to automatically create the data files for the BTR and BTW instructions and also to automatically create the ladder logic for the block transfers. So far so good. I think.
So here are my questions:
1. Do I have to do any additional configuration of the configuration words/bits other than what is done in the Setup Screen?
2. In the Raw Min and Raw Max fields do I enter 0 and 4095 for 4-20mA inputs?
3. What should my Data Format be? It defaults to BCD.
4. How do I get scaled data into my ladder logic since there is no SCP instruction.
Thanks,
Randy
