Hi,
Has anybody created any PV+ programs using RIO? I have lots of programs using the old classic type panel view with PDS software and I'm looking to convert.

I know that you can convert from PDS - 1400e - PV+, but this throws up lots of errors, I was wondering it is easier to convert and sort out the errors or just re-write it from scratch. The block transfer part seems especially iffy.

Also would it be again easier to scrap the RIO, put the PV+ on the DH+ network and re-write both the PLC and HMI programs.

Cheers

Hello,

I have also the problem.
Some tag´s are not converted and are in memory tag.
What kind of problem have you?
How can you testing the RSView Studio ME application on the RIO connection?

Just my $0.02 but you already have all the flags and stuff coming to integers or bits in the plc. If you switch to a DH+ or ethernet PV+ all you will need to do is design it properly to reference these same bits and eliminate the Block Transfers from the PLC. SHould be relatively easy. Just at first blush.

Hi Mulderm / Bob,
I have only converted the program through 1400e and then over into RSView machine edition and had a look at the errors etc. What I have done is tried to compare where some of the tags go back to in the new program with the old PDS program and some of them look to be going in the right place. My main problem with this is I like to write and group the tag database to make is easier to search and find things for people who will use it after me. After conversion all of the names are the same as the tags and in one folder.
For testing I was going to rig up a dummy PLC in my office and have it talk to the PV+ on RIO to test out the programs.

I do think Bob has a point though as putting the PV+ on the DH+ network would make it more robust in the matter of talking to other PLC's on the highway rather than messages back and forth. Again as he says all the integers and bits are there, it would mainly be a matter of re-writing the PLC program to remove the discrete I/O.

One question Why remove the discrete I/O? A DH+ PV can read Discrete Outputs and Write to Inputs as long as there is no real hardware consuming that address the PLC won't care. If necessary you can add a dummy module to hold place in the I/O descritpion.

That is one of the beauties of AB using an image table. You don't need hardwarre to use an Output or Input.

I did not know that would still work, that would make things much easier and quicker.

Thanks
