Communications between DF1 Wireless Gateway (105U-G / 905U-G) and Allen-Bradley PLC 19s
 |
BACKGROUND
The 905G DF1 Driver allows the 905G to communicate with Allen-Bradley devices supporting the DF1 protocol. Supported commands allow communication with 500 CPU devices (SLC and Micrologix) and with PLC2 series devices. The 905G will only support the full-duplex operation - this is the default DF1 mode on most equipment. DF1 full duplex is a “peer-to-peer” protocol. Both DF1 devices can initiate commands to the other device, and both devices will respond to commands from the other device. The 905G can act as both a command initiator and a command responder.
MATERIALS
The materials used for this application were,
Allen Bradley Micrologix 1500 PLC with programming cable,
RSLogix 500,
RSLinx,
905U-G-MD1,
905U-1,
E-Series Configuration Utility (Build 148 or higher),
RS232 DB9 serial cable.
APPLICATION
This application should be read in conjunction with the user manual for details on powering and programming the 905U Radio’s. The reader would also have a firm understanding of programming Allen-Bradley PLC’s using RSLogix.
To view the Elpro configuration save the zip file DF1 e-series config example to a folder on your PC. Open up E-series configuration utility build 148 or higher, select file/ restore project and locate the zip file saved on PC and select ok leaving Project Name blank. This will extract the files into this folder and load the configuration into the utility program.
