ControlLogix Data Highway Plus-Remote I/O Communication Interface Module About the ControlLogix Data Highway Remote I/O Communication Interface Module You can use the 1756-DHRIO module to communicate on a DH+ or remote I/O network.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 7 Set the Network Type and Node Address Switches Before you install the module, you must set the network type switches for each channel. If the network type is Data Highway Plus (DH+), you must also set the node address switches for that channel to a unique address within the range of 00-77. IMPORTANT If your module uses the 230k DH+ network, that is, Channel A switch set to 3, Channel B is disabled.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module Prepare the Chassis for Module Installation Before you install the DHRIO module, you must install and connect a ControlLogix chassis and power supply. Power Supply Chassis 43234 For information on installing these products, refer to the publications listed below.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 9 Determine Module Slot Location The figure below shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot and is always the leftmost slot in the rack (the first slot to the right of the power supply). You can use any size ControlLogix chassis and install the module in any slot. You can also install multiple 1756-DHRIO modules in the same chassis.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module Install the Module ATTENTION Do not force the module into the backplane connector. If you cannot seat the module with firm pressure, check the alignment. Forcing the module into the chassis can damage the backplane connector or the module. 1. Align the circuit board with top and bottom guides in the chassis. 2. Slide the module into the chassis. Make sure the module backplane connector properly connects to the chassis backplane.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 11 Remove or Replace the Module (When Applicable) 1. Push on upper and lower module tabs to disengage them. 2. Slide the module out of the chassis. 1 POWER POWER 2 43237 If you are replacing an existing module with an identical one, and you want to resume identical system operation, you must install the new module in the same slot.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module Wire the Connectors for the Module Channels Wiring Label 8-pin mini DIN programming terminal connection parallel to channel A when channel A is configured for DH+ communication.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 13 Connect the Programming Terminal and DH+ or Remote I/O Network 1. Connect the programming terminal to the 8-pin mini DIN connector. 2. Connect the DH+ or Remote I/O network to the channel A or B connector as appropriate.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module Check Power Supply and Module Status Alphanumeric status indicator illuminates and cycles through a sequence of messages (described on page 15). H+/RIO CHA CHB OK Module OK status indicator is solid red, then flashing green. Power Supply indicator is green. 43241 At powerup the module’s alphanumeric display begins a cycle through the following sequences.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 15 Troubleshoot the Power Supply If the alphanumeric indicator on the 1756-DHRIO module does not cycle through these messages on powerup, refer to the following table and to the Troubleshooting section that follows. If the POWER indicator is Power Supply Status is Recommended Action Off Not operating. Turn power switch ON. Check power wiring connections. Check fuse. On Operating. None, normal operation.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module Code Description Recommended Action CNFG FALT Incorrect DH+ routing table configuration. Correct the configuration. Refer to the 1756-DHRIO User Manual, publication 1756-UM0514. Incorrect Data Highway object configuration. Verify the module is inserted in correct slot. Data Highway Plus OK Normal operation for that channel. None. LINK Channel B is disabled because Channel A is used for 230k DH+ operation.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module 17 Interpret the Status Indicators The three status indicators on the module provide information about your module and the status of each channel. The following tables outline the indicator condition and the corresponding status, and explain what each condition means. If the Module OK indicator is Module Status Off Not operating. Recommended Action 1.Apply chassis power. 2.
ControlLogix Data Highway Plus-Remote I/O Communication Interface Module If the channel A or B indicator is in this channel mode then the channel status is take this action Off All Not on line. Place channel on line. Green RIO scanner Active RIO link. All adapter modules are present and not faulted. None, normal operation. DH+ Operating. None, normal operation. RIO scanner One or more nodes faulted or failed. Check power at other racks. DH+ No other node on the network. Check cables.
