Chapter 3 Configure Adapter Mode Introduction This chapter explains how and why to use the 1756-RIO module in adapter mode. In adapter mode, the 1756-RIO module can perform two functions simultaneously. First, the module can emulate one or more racks of I/O to a scanner, exchanging data with that scanner (for example, a PLC-5, PLC-3, or SLC controller). On Active racks, the module writes remote I/O inputs and reads remote I/O outputs. Second, it can monitor other remote I/O racks.
Chapter 3 Configure Adapter Mode Adapter Mode 1756-RIO Module as an Active Rack 1756-RIO Module as a Monitored Rack Rack 4 Rack 4 RIO Scanner (reads inputs and writes outputs to scanned racks) PLC-3, PLC-5, SLC, Etc. One-way communication between the Remote I/ O network and the ControlLogix controller. The RIO scanner controls the I/O and the ControlLogix controller via the 1756RIO module in adapter monitors all I/O data.

Appendix C Block Transfer Module Templates ATTENTION Anything after a semicolon on a line is treated as a comment and is ignored. Block Transfer Template Records Description A template usually contains a description record, which consists of the keyword Desc, followed by an equal sign and up to 79 characters of text enclosed in quotes. The description text displays in the configuration dialog box for any modules created from the template.
Block Transfer Module Templates Appendix C Block Transfer Lengths A block transfer has three lengths associated with it. CfgLen The configuration length, ’CfgLen’, is the length of the additional configuration block transfer write data sent once to the block transfer module to initialize it. BtwLen The block transfer write length, ’BtwLen’, is the length of the block transfer write sent to the module during normal data update.
Appendix C Block Transfer Module Templates The configuration program uses the default configuration data to select the initial values when you create a block transfer module from the template. EXAMPLE CfgData[ 4]=0x8000 ; 0-3:DataPol, 4 6 8 10:MinScaPol, 5 7 9 11:MaxScalPol, 15:BinFmt CfgData[ 5] ; Min Scale ch 1 Parameters Parameters let you assign values to the configuration data different from the default values for a specific module created from a standard template.
Block Transfer Module Templates Appendix C The shift is the number of bits. The value you enter is shifted left, from 0…15. It is specified by the keyword ’Shift’, an equal sign, and the shift value. The mask selects bits in the value you enter. It is specified by the keyword’Mask’, an equal sign, and the mask value, usually in hexadecimal. The value you enter is logically ANDed with the mask, shifted left by the shift value, and ORed into the configuration word given by the offset.

Block Transfer Module Templates Appendix C Aliases Aliases define the names and descriptions exported from the configuration program and imported into the RSLogix 5000 project. They begin with keyword ’AliasInp’ or ’AliasOut’, an offset enclosed in square brackets, a name consisting of up to 15 characters enclosed in quotes, and a description consisting of up to 79 characters enclosed in quotes.

Appendix D Troubleshooting Display and Status Indicators This section covers problems that may occur with your 1756-RIO module.
Appendix D Troubleshooting Display and Status Indicators Status Indicators The 1756-RIO module has three status indicators to indicate the state of internal operations. The status indicators are labeled RIO, CLX, and OK.
Troubleshooting Display and Status Indicators Appendix D Adapter Mode In order of priority, highest first. Indicator Status Description RIO Red A frame-receive error has been received in the last second (CRC error, abort, or time-out). Indicator stays red for 1 second after the error occurs. Flashing red/ off One or more racks are not being scanned. Flashing green/ Configuration mismatch on one or more racks. off Green All racks are being scanned and there are no configuration mismatches.
Appendix D Troubleshooting Display and Status Indicators OK Status Indicator – Module Health Indicator Status Description OK Green Indicates that module has passed all power-up diagnostics and is functioning normally. Red Indicates that module startup diagnostics failed, or a major module fault such as watchdog time-out, or jabber inhibit occurred.
Troubleshooting Display and Status Indicators Appendix D Watchdog and Jabber Inhibit A watchdog timer is implemented in the module’s hardware. If the firmware does not kick the watchdog within the time-out period, the watchdog times out and generates a fatal error with error code D1. In scanner mode, the module stops scanning. In adapter mode, all racks stop communication. A jabber inhibit timer is implemented in the module’s hardware.

Appendix E Quick Start ControlLogix System Quick Start Use the following steps to quickly get the module running in a ControlLogix system. Detailed information about each step is available in other sections of this manual or in the installation manual. You can have only one scanner per RIO network. Remove any other scanners on the RIO network before continuing. The RIO module ships in scanner mode. You can adjust the instructions to fit the mode that matches your needs. 1.
Appendix E Quick Start 9. Enter the module name and slot number. See page 24. 10. Click the Change button in the Module Definition section. Select your desired mode, scanner or adapter. The module ships in scanner mode. Note the number of input/output tags. If this number is not the same after you map your data with the configuration tool, you will have to return to this screen and change them to match your configuration.
Quick Start Appendix E 19. Download the configuration to the module. From the configuration tool’s Configure menu, choose Download Configuration. Set the communication path when prompted. See page 91. 20. Save the project. 21. Go online in the RSLogix 5000 project and download the configuration to the controller. See page 30. See Chapters 2 and 3 for in-depth information on setting module modes and configuration.
