Connecting older DH+ PLC5S and SLC 5/04s to latest Ethernet products

Numerous processing plant clients are searching for an answer for interface their more seasoned AB PLC5s and SLC 5/04s on AB DH+ to speak with more current Ethernet AB PLCs like the SLC 5/05 and PLC5s and perform RSLINX/LOGIX PLC programming by means of Ethernet.

 

Which PLC5 do you have?

Picking your answer will rely upon whether you have a more seasoned unique PLC5 or the cutting edge PLC5s according to beneath:

The first AB PLC5/10, 5/12, 5/15, and 5/25 have 2 communications ports which incorporate Allen-Bradley Data Highway Plus DH+ or AB Remote (RIO).

The up and coming age of the PLC-5 processors incorporate 5/11, 5/20, 5/30, 5/40, 5/60, 5/80 which have DH+ and Remote I/O ports, and a 25 pin RS232 communication with DF1 convention with the choice of requesting with an Ethernet or ControlNet port.

 

What are my Ethernet to DH+ choices?

On the off chance that you are needing to keep your current DH+ PLCs5 and SLC 5/04s in your present establishment and need to interface more up to date Ethernet gadgets, here are two alternatives:

AB Controllogix Gateway 1756-DHRIO Processor

1 - Connecting older DH+ PLC5s and SLC 5/04s to latest ethernet products

Controllogix 1756 DH+ to Ethernet Gateway that is utilized to connect from Ethernet to 2 DH+ networks at speeds of 57.6Kb, 115.2Kb and 230.4Kb.

The benefits of the 1756 is that it enables one Ethernet Gateway to numerous networks including ControlNet, Devicenet, DH+, DH-485. It has direct access to PLC-5 Data Tables with no programming required to connect from Ethernet to DH+

Tragically, this is a costly single answer for your PLC5 on DH+:

1756 Package:

1756-A7: 7 SLOT CONTROLLOGIX CHASSIS

1756-ENBT: CLX ETHERNET/IP BRIDGE

1756-PA75: 85-265V AC POWER SUPPLY

1756-DHRIO: DH+/RIO BRIDGE Over

 

Prosoft A X2-AB-DHRIO

1 - Connecting older DH+ PLC5s and SLC 5/04s to latest ethernet products

EtherNet/IP Converter to Allen Bradley Remote I/O or DH+ Gateway

Prosoft’s A X2-AB-DHRIO is an EtherNet/IP to Remote I/O or DH+ converter that is intended to enable customers to start a phased migration way to deal with replacing or redesigning legacy Remote I/O, HMI’s or Drives. It is an adaptable gateway that works with most Ethernet hardware permitting messaging between RSLINX/LOGIX to DH+ or communications between more up to date AB Ethernet PLCs to more established PLC5s and SLC 5/04s on DH+

 

AB 1761-Net-ENI DF1 to Ethernet/IP converter

(note just accessible with most recent PLC5 Processors)

2 - Connecting older DH+ PLC5s and SLC 5/04s to latest ethernet products

This arrangement will permit your RS232, DF1 CH0 serial port on your PLC5 communication path to AB Ethernet/IP.

The advantages of this arrangement is that it is the most economical alternative and have direct access to the PLC5 Data Table with inherent email capacities and ENI configuration done with a free utility.

Limitations include permitting just 3 of the same bi-directional connections to the PLC5 at any given time. The PLC5 serial port just has serial communication speeds of 19.2Kb.
