Remote I/O Pass-Through using DH+
Remote I/O terminals allow the transfer of applications from a
computer on the Allen-Bradley DH+ link to a PLC-5 or SLC-5/04
controller. The controller passes data to the PanelView terminal over
the Remote I/O network.
To transfer an application using Remote I/O Pass-Through:
1. A Data Highway Plus Interface Module must be installed in the
computer. Allen-Bradley offers a variety of interface cards for a
DH+ connection between a computer and a controller.
2. The appropriate communication driver must be configured on
the computer.
3. Connect the computer to the PLC. See the instruction sheets
provided with the communication module or card to select the
proper cable. Connect the cable between the computer and the
controller.
4. Pass-Through must be enabled for the terminal. Check the RIO
Configuration screen on the terminal’s Configuration Mode
menu. Pass-Through is enabled using the out-of-box application
provided with the terminal or when defining Remote I/O
parameters in the PanelBuilder32 software.
5. Refer to the online help in the PanelBuilder32 software for
procedures on how to transfer applications using Pass-Through.
