Hi All,
I am looking for some advice regarding the correct steps that should be taken if I was to replace an existing (but now obsolete) Third party drive, with a Rockwell Powerflex 70.
The network scanner is a 1747-SDN residing in a chassis with an SLC500 5/05.
The adapter will be the usual 22-Comm-D.
There are several obsolete drives on the network.
I've seen several different means of achieving the above, with some subtle differences.
I'm fairly familiar with RS500/RSNetWorx for DNET etc, but looking for some expert help in the correct /most effective sequence of steps to do this.
Also, assuming that the network has been setup and operating for several years, I would guess that I will not have to make any changes between SDN card and controller?
This is currently done in the controller program by means of a copy instruction that moves I/O data between M0 & M1 buffers to/from the PLC/Scanner into Integers.
I have also noticed that there are also discrete input /output addresses used in the program (e.g. the run signal to the scanner) and have never fully grasped the difference between the "M0/M1/Integer data" AND typical discrete addresses such as "I:2 / O:2" etc also used for each device on the network when it comes to the scanner mapping and PLC code
My thoughts on the correct steps would be:-
1.Go online to the current network using RSNetworx and backup the working configuration as a fall back.
2. Go Offline and remove the device from the Scanlist then download the revised scanlist to the 1747-SDN
(Do I need to stop the scanner from running before downloading?)
3. Remove the old device from the network.
4.Configure the Comm-22-D adapters baud rate to that of the established network.
5. Physically connect the new device to the network with its default node 63
(or can the new adapter have the original node address as the old one is no longer in the scanlist?)
6. If required, use the EDS wizard to register the file for the new drive.
7.Use the drive commissioning tool to change the node from 63 to the same node as the decommissioned drive
6. Add the new drive to the Scanlist
7. Assuming that the I/O for the new drive will differ from the old one, then remap to the M0 & M1 buffers via the scanner properties tab
(Not sure if this is wrong and that maybe I should be mapping to the discrete I/O areas directly)
7. Download the revised Scan list to the Scanner.
(Do I need to take the scanner out of run at this point?)
8.Assuming all is healthy, then add the relevant PLC logic for the drive.
Anything incorrect or missed or folks?
