The attached document contains both read and write message samples from a ControlLogix, CompactLogix, and SLC 5/05 processors to an SLC 5/04s and PLC5 processor on a DH+ network through the DH+ bridge gateway....
Read moreWhat 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 AN-X(2)-AB-DHRIO gateway in the driver configuration. The gateway emulates a 4 slot ControlLogix chassis with an ethernet module and a DH+ bridge module in the...
Read moreWhat OPC Servers will work with the AN-X(2)-AB-DHRIO gateway running the DH+ firmware?
There are several OPC servers that have been tested or are known to work through the AN-X(2)-AB-DHRIO running the DH+ bridge firmware: RSLinx Classic using the Ethernet Devices driver Wonderware using the DASABCIP driverKepware using the ControlLogix Ethernet driverAdditional OPC...
Read moreWhat are common things that prevent reliable DH+ communications on the AN-X(2)-AB-DHRIO 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 u...
