use FTV tools restore runtime file this should bring in you will probably want to look over the ver 7.0 .mer file for errors after restoring from an older version

if you are using an RSlogix 5000 controller it is pretty straight forward the comunications module is slot 0 then the next to the right would be slot 1 etc. once the module appears in your tags list you can just use a mouse to click on the proper input or output. Remember to set up your modules in your offline program exactly like the physical ones as you will get a module mismatch otherwise.

Thanks Ken I am still in suspense on updating to 21 vs 23 or 24 so may just Try Flashing it to 20 again. I am not real sure what the module Keying does in I/O is it very important for digital I/O to be comapatable keying.

I just flashed up an L16 with firmware 20.01 when I turned it on I got a fault on the on board IO showed not recognized device I can disable keying to the module and the fault doesn't happen the IO seems to work fine, but why wouldn't the module be compatible keying at this point I have put several of these into service using the same firmware with no problems just wondering if I should report this and try to get a replacement unit out of Rockwell or if leaving the Keying disabled for the on board IO will be alright. By the way an add on 4 point analog card is fine with compatible keying.

I guess if it works however I had read that the source and destination should be of the same type in COP instructions. I assumed that meant they had to be but after reading the text again "Important: the Source and Destination operands should bethe same data type, or unexpected results may occur." From RSL 5000 Instruction Manual just means things might not work out if you copy say a REAL into a DINT then try to manipulate so I now concur with JRoss and b_carlton I will try to remember this next time I run into a similar situation

JRoss I read this as moving two INT's GenericModule:I.Data.[0] and GenericModule:I.Data.[1] into one DINT MYDINT_1 I think the BTD instruction would be the more compact way of building MYDINT_1

This will take two BFD instructions which you might or might not want triggered on every scan

use bit field distribute instruction to build 2 INT into 1 DINT, make sure MSData and LSData are in the proper order

Dave: Have you already purchased this Pico if not you might want to look into the micro 810 12 point controller instead. The processor is even cheaper and the free software has built in Help for programming also online videos for several common task are available and you are more likely to run into these in the future because the Pico line is obsolete. but if you are locked into a Pico I remember there being free downloadable manual for Picosoft 6 at AB.com if they have not taken it down.

PID loops are never simple if you have a 10 degree temp. range you are controlling with on/off control you probably can get by with latching and unlatching an output. You would need to have a purpose to set up an analog control loop such as cutting in and out multiple contacts to hold to within one or two degrees to need to use a PID loop if you do use one yes you will have to find the proper level for each gain there are several post here already on how to set up PID gains.

A few years back had a similar problem with Flex I/O was a firmware issue with the Ethernet adapter I have not used any of the Gaurdlogix Point I/O but AB may have a similar issue. Also it looks like that is the only safety output card on either adapter so I would also check for known issues with that card.

RSlogix 500 is a programming software package that allows use of several different controllers if you are using one of the newer ones such as a micrologix 1100 there is a built in high speed counter that used with a simplified encoder wheel can do what you want although you will need to use the inputs in a different order I0:/0 = input A I0:0/1 = input B reset if I remember right is on I0:0/2 using the built in quad encoder counter. if you have to build your own encoder in software for an older style SLC look into masking a word to control your counter direction.

Hey Conor: I would look at varying the speed on both motors to keep the RPM/s up as much as possible depending on the pump low RPM operation could result in inefficent operation and most standard duty motors like to stay above 50% of there rated speed to limit heat build up in the windings but most of this depends on specifics of what type of motors and pumps are being used. and how far from your target pressure/flow a single pump gets you.

I have had pretty good results letting FTV resize to fit using the 640x480 reselution the print may be a bit small but still ledgible on the 6" screen I think you would need to do some customising if you went down any further than that
