You can use any size ControlLogix chassis and install the module in any slot. You can also install multiple DNB modules in the same chassis. The input structure consists of one bit status register and a variable size bit array of up to words for input data.
Wear an approved wrist-strap grounding device. Identify Module Components Use the following figure to identify the external components of the module. For a UCMM capable device, this means the device has one or more established connections. Check for disconnected cables. Touch a grounded object to discharge manula potential. This was pushed as it was thought that this was a “Reset” button. Enter a scan list.
Worn contacts may create electrical resistance that can affect module operation.
ControlLogix DeviceNet Scanner Module Installation Instructions_百度文库
Scanner is in IDLE mode, outputs are not under control, and inputs are being consumed. Slave device in scan list table does not exist node number alternately flashes.
Hi guys, We had an issue today where we were getting comm’s errors on one of our DeviceNet loops. This module is sensitive to electrostatic discharge. The alphanumeric display flashes the codes at approximately 1 second intervals.
manul Posted 25 Oct If this product 1756-snb batteries, they must only be changed in an area known to be nonhazardous. It is one of two loops on the only ControlLogix that we have on-site. Do not touch the backplane connector or connector pins. We thought that there was a fault on the PLC. This code clears itself once scanner attempts to initialize all slave devices on the network.
Verify that the correct device is at this node number. Identifies information that is critical for successful application and understanding of the product. Check slave device configuration. The scanner module periodically updates the contents of the status structure and copies its contents to the controller. No network power detected on communication port. Prepare the Chassis for Module Installation Before you install the module, you must install and connect a ControlLogix chassis and power supply.
Tighten the screws on the connector as needed.
Thanks for your help Fuzzy. Slave device is returning error responses when scanner attempts to communicate with it node number alternately flashes. Follow these guidelines when you handle the module: Anyway, we changed out a compact block that was faulty.
Manual 1756-dnb/e eds
Scanner is detecting communication errors. For a Group 2 only device, this means that the device is not allocated to a master. Inspect the slave devices and verify connections. Baud rate, or 5. Sign In Sign Up. The device may not be powered.
Recommended Action Check DeviceNet connections and physical media integrity. The DNB has at least one connection to it from a controller.
User has disabled communication port. Scanner is in 1756–dnb mode when it Null Master Slave Dual contains an empty or disabled scan list out-of-box default. Make sure the module properly connects to the chassis backplane. You need to be a member in order to leave a comment.
Condition off green flashing green 1 1 Indicates Scanner is not mankal. Condition off Status no power Indicates No power applied to device. Recommended Action Modify your configuration and check for invalid data.

The bit status register reflects the current state of several key module-level operational parameters. It does this by allowing the scanner to perform as a slave device 1756dnb another master on the network. It has been designed and tested to meet the following 1576-dnb. Preventing Electrostatic Discharge The DeviceNet scanner module is sensitive to electrostatic discharge.
You can install as many modules as your power supply can accommodate i. Device has an unrecoverable fault and may need to be replaced.
