What driver should be used in RSLinx Classic to browse or get data from PLC5 or SLC controllers on a DH+ network?
The best driver to use in RSLinx Classic is the Ethernet Devices driver. Specify the IP Address of the ANC-100e gateway in the driver configuration. The gateway emulates a 4 slot ControlLogix chassis with an ethernet module and a DH+ bridge module in the chassis (with just the A channel).
There are several OPC servers that have been tested or are known to work through ANC-100e running the DH+ bridge firmware: RSLinx Classic using the Ethernet Devices driverWonderware using the DASABCIP driverKepware using the ControlLogix Ethernet driver TopServer using AB controLogix Ethernet Driver PeakHMI AB PCCC SLC Master Driver Additional OPC Servers may work with […]
The ANC-100e and ANC-120e can communicate with any of the 77 nodes on DH+ which includes the Controllogix 1756-DHRIO DH+ processor, as well as legacy PLC-5s and SLC 5/04s.
Yes, ANC-100e are capable of communicating via EtherNet/IP with a control Logix system that has a redundant processor.
The default IP Address is 192.168.137.2
What are common things that prevent reliable DH+ communications on the ANC-100e gateway running the DH+ Bridge FW?
If the NS or NET LED is not solid green then check the recommendations below:
1) For networks running at 57k6 or 115k2 bauds it is necessary to have 150 ohm resistors on each end of the network (for 230k4 use 82 ohm resistors)
2) Ensure that at least 10′ or 3 meters of cable is used between gateway and any surrounding nodes
3) Ensure that the outer braided shield has been grounded in one place to reduce noise
Here is a Software list of products that work the ANC DH+ converters. These software packages can access the ANC-100e with an Ethernet/IP port and the ANC-120e with a USB port, both using Controllogix Ethernet/IP drivers :
The ANC-100e’s Data Highway Plus firmware does not have a specific limit on the number of nodes it can communicate with (beyond the inherent limits of the DH+ protocol itself), however, be aware that DH+ is a serial based token passing protocol, and thus there will be significant delays in update rates for each additional node on the network that may hold the token.
SLC full name is “Small Logic Controller”. The first SLC, Known simply as an SLC500, was an integrated platform containing the CPU, power supply, and IO all in one package. with 1K of memory and was used in small i/o application
Nowadays with so many technological updates the serial ports or the PCMCIA slots are outdated. Meaning that the new options in computer hardware doesn’t contain them.
