  • Page 5: Overview

    The Allen-Bradley Ethernet Driver provides a reliable way to connect Allen-Bradley Ethernet devices to client applications; including HMI, SCADA, Historian, MES, ERP, and countless custom applications. This driver sup- ports the Allen Bradley SLC 5/05 series, PLC-5 series, and SoftPLC PLCs. Address ranges are open to support future models for this series of PLCs.

    Allen-Bradley Ethernet Driver Setup Communication Protocol Allen-Bradley Ethernet Supported Devices SLC 5/05 processor* PLC-5 series (excluding the PLC-5/250 series) SoftPLC *Address ranges are open in the driver to allow for new devices. The driver may support a device even if it is not listed above.

    Allen-Bradley Ethernet Driver For information on reserved characters, refer to "How To... Properly Name a Channel, Device, Tag, and Tag Group" in the server help. Description: User-defined information about this channel.  Many of these properties, including Description, have an associated system tag.

  • Page 8: Channel Properties - Advanced

    Allen-Bradley Ethernet Driver Write All Values for All Tags:  This option forces the server to attempt to write every value to the con- troller. In this mode, the server continues to gather write requests and add them to the server's internal write queue.

  • Page 9: Channel Properties - Communication Serialization

    Allen-Bradley Ethernet Driver Inter-Device Delay: Specify the amount of time the communications channel waits to send new requests to the next device after data is received from the current device on the same channel. Zero (0) disables the delay. Note: This property is not available for all drivers, models, and dependent settings.

  • Page 10: Device Properties - Identification

    Allen-Bradley Ethernet Driver Is the channel using a serial or Ethernet driver? Does the driver read tags in separate requests, or are multiple tags read in a block? Have the device's Timing properties (such as Request timeout and Fail after x successive timeouts)

    Allen-Bradley Ethernet Driver Rate. The data is not saved if the server removes the item (such as when the server is reinitialized). The default is No. Notes: 1. This System tag (_Simulated) is read only and cannot be written to for runtime protection. The System tag allows this property to be monitored from the client.

  • Page 12: Device Properties - Auto-Demotion

    Allen-Bradley Ethernet Driver Communications Timeouts Connect Timeout:  This property (which is used primarily by Ethernet based drivers) controls the amount of time required to establish a socket connection to a remote device. The device's connection time often takes longer than normal communications requests to that same device. The valid range is 1 to 30 seconds. The default is typically 3 seconds, but can vary depending on the driver's specific nature.

  • Page 13: Device Properties - Communications Parameters

    Allen-Bradley Ethernet Driver Demote on Failure: When enabled, the device is automatically taken off-scan until it is responding again. Tip: Determine when a device is off-scan by monitoring its demoted state using the _AutoDemoted system tag. Timeouts to Demote: Specify how many successive cycles of request timeouts and retries occur before the device is placed off-scan.

    To correctly use the Generic Module, users must know the number of Input and Output words required for each module. Consult Allen-Bradley I/O user manual documentation to confirm Input and Output requirements and be aware that requirements may be different based on Class 1 or Class 3 operation.
