Telemecanique Magelis HMI to AB PLC 5 on DH+

admin — Sun, 06 May 2012 14:09:23 +0000

I would like pricing and more information on the GW1000-ABEIP. I have an application where I want to connect a Telemecanique Magelis HMI and a PC running custom software using ethernet to a Allen Bradley PLC5 on DH+. How does the GW1000ABEIP route to the specific DH+ nodes? Is this configurable? Do I use CIP at the HMI end? Does it happen automatically based on IP address?

Thanks for your inquiry. The GW1000-ABEIP will work great in your application allowing the Telemenanique HMI via Ethernet/IP protocol communicate with your PLCs via DH+. Other driver options include AB Ethernet or ModTCP protocol. Configuration is done via Telnet or Web Screens in which you would choose a unique DH+ node address.

Ethernet/IP to SLC 5/02 on DH-485

admin — Thu, 08 Dec 2011 22:05:12 +0000

I want to discard my 1747_pic converter for good and communicate to my SLC 5/02 which communicates using the PIC Driver etc.

I believe this is the correct product to use to communicate using ethernet/ip driver in laptop to your device then out your device into rj45 port of plc.

Thank you for your inquiry. The SLC 5/02 processor communicates using DH485 protocol and DH485 signal levels. Since DH485 is becoming less popular over the years, we have removed the circuitry required to support DH485 signal levels from our standard product. The GW1000 series will support Ethernet to DH+, serial to DH+, or ethernet to DH485 over the RS232 port, depending on firmware version loaded. The DH485 communication protocol is supported, but only over the RS232 port voltage levels. For those customers wishing to connect the GW1000 to a network of DH485 equipment, a 1761-NET-AIC module will be required. The product to order is GW1000-ABEIP-DH485.

Connect a serial D9 to D9 null-modem cable between the RS232 port on the GW1000 to the RS232 port on the 1761-NET-AIC. Connect the screw terminals of the 1761-NET-AIC to the DH485 equipment network.

Redundant SCADA server to DH+ PLCs

admin — Thu, 08 Dec 2011 22:02:25 +0000

1. Will this device work as a common connection from redundant SCADA servers to DH+ PLCs (PLC5)? Both SCADA servers are on-line and poll simultaneously. Yes, up to 4 connections are supported

2. Will this device work with servers running MS Server 2008? Please consult your software vendor for compatibility with MS server 2008.

3. This device will be mounted within a server rack with 110 VAC only. Is there a power supply option to accommodate this? We do not sell power supplies. Please source a 24 Volt DC power supply. The GW1000 consumes approximately 100mA, so a power supply with a 500mA rating is plenty. The device ships with screw terminals for power supply connection. The GW1000 can also be powered by a USB port, however, we don’t recommend USB power for large DH+ networks. For maximum reliability, we recommend an external 24Volt DC power supply.

GW1000-ABEIP-DH-485 Controllogix to DH-485

admin — Thu, 08 Dec 2011 21:46:13 +0000

Q. We have a customer wanting to connect PCs on Ethernet/IP (A-B) to SLCs on DH-485. Also to connect C-Logix on Ethernet/IP to SLCs on dh-485. I believe the DL-GW1000-ABEIP-DH-485 is the device?
A. Since DH485 is becoming less popular over the years, we have removed the circuitry required to support DH485 signal levels. The base unit will support Ethernet to DH+, serial to DH+, or ethernet to DH485 over the RS232 port. The DH485 communication protocol is supported, but only over the RS232 port voltage levels. For those customers wishing to
connect the GW1000 to a network of DH485 equipment, a 1761-NET-AIC module will be required. Connect a serial D9 to D9 null-modem cable between the RS232 port on the GW1000 to the RS232 port on the 1761-NET-AIC. Connect the screw
terminals of the 1761-NET-AIC to the DH485 equipment network.”

Q. Does this allow full access for PLCs, PCs etc from the ethernet/IP side to the DH-485 side?
A. Yes, the GW1000 can accept simultaneous connections over ethernet from PLC’s, and PCs, and convert to DH485 protocol over the RS232 D9 connector. Please be sure to install a 1761-NET-AIC if you need to connect to a network of DH485 equipment.

RSLogix 500/RSLINX Download/Upload to SLC 5/04

admin — Thu, 08 Dec 2011 21:42:07 +0000

Q.Will GW1000-ABEIP allow download/upload and online monitoring with RSLogix500/RSLinx to SLC 504 over Ethernet? Looks like it, but “sending data” is not always the same as programming software connection.

A. Yes, going online and programming a SLC 5/04 processor is a very common application for our GW1000-ABEIP. Please see the GW1000-ABEIP application notes l

PLC-5 / SLC 5/04 to DH+

admin — Tue, 08 Nov 2011 03:08:36 +0000

Q: How do I interface a legacy PLC-5 / SLC 5/04 via DH+ to AB’s Ethernet/IP or Ethernet TCP/IP?

A: Our GW1000-ABEIP will allow RSlinx & RSLogix to access DH+ via Ethernet TCP/IP.

PLC5s to Ethernet/IP

admin — Tue, 08 Nov 2011 03:07:33 +0000

Q: Why would I go with your GW1000-ABEIP instead of upgrading all my AB Equipment (ie. PLC5s) to Ethernet/IP?

A: Cost. You only need one GW1000-ABEIP per DH+ at a cost of $1,395 list. You don’t have to upgrade each PLC5 processor on DH+ to a PLC5E . This can save significant money if you have a big DH+ Network. This functionality allows RSLinx/RSLogix on Ethernet/IP have access to all the nodes on your DH+.

More About the GW1000-ABEIP:
DataLink now offers the GW1000-ABEIP that significantly reduces your AB Ethernet upgrading costs as you don’t need to replace each DH+ PLC processor/device.

Simply make the GW1000-ABEIP a node on DH+ and then interface to your AB Ethernet. AB PLC users can interface bi-directionally between Allen-Bradley Data Highway Plus (DH+) / DH-485 and AB Ethernet (CIP & 2222 protocols).

Modbus TCP/IP to DH+

admin — Tue, 08 Nov 2011 03:06:17 +0000

Q: I would like to interface my Modbus TCP/IP Network to AB’s Data Highway Plus DH+ so I could extend the life of my PLC’s without Ethernet Interfaces? Do you have a product that will do this?

A: Yes, our GW1000-MODTCP.
