Hi everyone Just did the changes! My input was 152 so I had to change the DM 1507 (high scaling point) from 800 to 600 and my scaling is correct. This was setup in a move block so I didnt use the Systools but I had a go at that on my test rig and its excellent, thanks PDL! I had to refer back to find out you must power off for changes to the card to take place which had me tricked for a little while though! TFC

Thanks PDL I will have an attempt at this later in the day! Excellent!

I guess that would work but it is not the best practice. If you have a range of 0 - 800 you should change that range, not add more code to change the range to what you would like. I dont know how to change the input range on this system so I guess I will have to wait till he weekend is over and call my Omron dealer.

Hehe I cant believe how easy it is and how silly I am! Oh well

Hi Ken Thanks for the prompt reply I have downloaded the only V10 code which I will attach to this reply. This has all the logic for setting up the card I believe. I am getting lost at trying to write some test words to the MCM card will will then by transferred to the DCS. I have a Control Logix and a test DCS node that I can run these tests online once I get my head around it (lost at the mo). When I use the term "write" I am using it to explain the movement of data from Controlloer through the backplane to the output image to the MCM card, I think this is right terminology? This is my first Control Logix job on this site but this is the first of many all to use MCM cards. Im at work all weekend to work this out. mvi56mcm_expanded_v10.ACD

Hi all I am trying my first ever attemp at programming a MVI56-MCM modbus card with a Control Logix PLC. At the moment I am very confused trying to understand to register mapping and the whole process at the moment. I am aiming to communicate from a slave CLX to Master DCS. I have my DCS side sorted. In the manual it says words 0 - 4999 is equal to Modbus registers 40001 - 45000 which is fine. My DCS start at 40001. I dont understand how to move values in the CLX to the 0 - 4999 registers? Does anyone have example code they could post? The card comes with setup software but doesnt give examples of actually writing values Regards TFC

Hi all Yes, Im back out the bush and have just had some spare moments to look at this card. Yes KinK, as my mA value changes the voltage level is changing at the terminals. Im getting about 4vDC when I sinking 20mA. I even put a new card and still no chnage in value. What the heck am I doing wrong! All the AD003 dip swtiches are turned off. On the Cpu, The first two dips are off, the next four are all on. I want to get over this but Im stuck and feel really stupid

Sleepy Wombat has got me thinking about my ladder logic. If bit 253.13 is only on for the first cycle, I currently have that bit in front of my MOV statement for moving IR 151 to DM120. Perhaps this is why I dont see a change in value? As posted previously, I wont get a chance to test until Tuesday. TFC

Hi KinK I work remotely and I have flown back into town so I wont be at my desk at work where I have the Omron setup for this little test I am trying to do until Tuesday. Please find attached a word doc with drawing of my connections. OmronAD003.doc

Here is my basic code, attached. I cant get this dang analogue to work. I have all V+I+ input pairs shorted. I have the 24VDC ive on the V1-ve terminal, the 24VDC +ve out of the power supply into the my milli amp simulator and the other lead onto the I+ terminal. I have matching IO tables in PLC and Syswin. I have proper circuit as my ma circuit is made and I can change out between 4-20ma. The manuals are starting to look like white on rice on a paper plate in a snow storm. TFC RYAN.SWP

I now have the digital working, didnt have same IO table in Syswin and PLC. Still unable to get my analogue input working though.....

Thanks for the reply guys. Even by setting Kink's lead I was unable to register a change in input value. I have since added a 16PT digital input card and guess what, I cannot get that input to turn on in my program. I am new to Syswin and Omron so Im sure Im doing something real stupid but for the life of me I cannot work it out. Some more direction would be very appreciated

Hi I am trying to Omron for the first time using C200HG and am having probs. I have a 10 slot backplane, Cpu and power supply and a AD003 analogue input card mounted into slot 1. The switch on the AD003 is set to 5, hence I should be using IR 150 onwards. In my program I have a MOV instruction trying to copy the contents of analogue input 1 into DM120. Here is where my problem starts. I cannot read a ma signal in. I am not sure if it is hardware or software I have 24VDC -ve on V1-, V1+ and I1+ are linked. I am them putting the 24VDC +ve through my Fluke 20ma simulator and the other end of my fluke onto I1+. When online I read no value at IR150 in my MOV instruction. Before my MOV instruction I have an always on bit. In the Omron manuals it talks about setting up the analogue card but I dont understand how to do it. If someone can help me set up this first analogue input Im sure I will get it. Thanks
