AB Controllogix Gateway 1756-DHRIO Processor
Controllogix 1756 DH+ to Ethernet Gateway that is used to bridge from Ethernet to 2 DH+ networks at speeds of 57.6Kb, 115.2Kb and 230.4Kb.
The Benefits of the 1756 is that it allows one Ethernet Gateway to many networks including ControlNet, Devicenet, DH+, DH-485. It has direct access to PLC-5 Data Tables with no programming required to bridge from Ethernet to DH+
Unfortunately, this is an expensive single solution for your PLC5 on DH+:
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
EtherNet/IP Converter to Allen Bradley Remote I/O or DH+ Gateway
Prosoft’s AN-X2-AB-DHRIOis an EtherNet/IP to Remote I/O or DH+ converter that is designed to help customers initiate a phased migration approach to replacing or upgrading legacy Remote I/O, HMI’s or Drives. It is a flexible gateway that works with most Ethernet equipment allowing messaging between RSLINX/LOGIX to DH+ or communciations between newer AB Ethernet PLCs to older PLC5s and SLC 5/04s on DH+
AB 1761-Net-ENI DF1 to Ethernet/IP converter
(note only available with latest PLC5 Processors)
This solution will allow your RS232, DF1 CH0 serial port on your PLC5 communication path to AB Ethernet/IP.
The benefits of this solution is that it is the least expensive option and have direct access to the PLC5 Data Table with built in email capabilities and ENI configuration done with a free utility.
Limitations include allowing only 3 of the same bi directional connections to the PLC5 at any given time. The PLC5 serial port only has serial communication speeds of 19.2Kb.
