A-B Networking
(OP)
I would like to the best combination for networking the following plcs:
(2) PLC-5
(7) SLC-5/04
(1) MICROLOGIX 1500
Let me also say I am only looking to retieve data, not program remotely. I am looking for the following information from the machines
1) parts counts
2) faults
3) number of fault per shift
4) up/down time percentage
Any help you can give me would be greatly appreciated.
Regards,
Afterhrs

With the mircrolix 1500 processor, you are pretty much limited to ethernet.

You have to look at the available networks for each of the processors:
PLC-5 DH+ and DF1
SLC5/04 DH+ and DF1
Micrologix 1500 DF1
DF1 is AB's RS232 serial communications protocol. This is point to point. There are adapters to convert to AB's DH485 network.
DH+ is a relatively high speed peer to peer network. You will need a special interface in your SCADA computer for this network. I would say that for any reasonable size system (<1000 points) you would have no problems using DH+. I believe that there is a DH+ module available for the MicroLogix 1500.

Now it looks like we are going to hire a contractor,
but it is always nice to know wich means of comms A-B
prefers to use.
We also have some information on RS Bizware and RS View.
Some people already like Bizware because it seems to be a lot closer to plug and play.
Thanks Again,

1. Often the serial port on the PLC5s and the SLC5/04s (where you would put a 1761-NET-ENI to get an ethernet connection) is allready used up by some other application (HMI screens typically).
2. You dont have to put everything on the same network. RSLinx and other drivers can be set up to use several communication channels at the same time.
You allready have DH+ for free on the PLC5s and SLC5/04s.
Consider using a DH+ network for your PLC5s and SLC5/04s, and an Ethernet network for the ML1500 and possibly new additions to the system.
