ControlLogix DeviceNet Scanner Module Installation Instructions_百度文库
The display starts at the current Manuap ID and cycles through all legitimate the network node addresses Check DeviceNet connection on front of module. Touch a grounded object to discharge static potential. Baud rate, or 5. Recommended Action Check DeviceNet connections and physical media integrity. Register a new account. Slave Mode The slave mode feature allows processor-to-processor communication.
Verify that the correct device is at this node number.
1756-DNB configuration button
Device has an unrecoverable fault and may need to be replaced. This module is sensitive to electrostatic discharge. Anyway, we changed 1756-db a compact block that was faulty. Prepare the Chassis for Module Installation Before you install the module, you must install and connect a ControlLogix chassis and power supply.
The scanner module periodically updates the contents of the status structure and copies its contents to the controller. Put controller in RUN mode. Hi guys, We had an issue today where we were getting comm’s errors on one of our DeviceNet loops. The bit position of each of the 64 bits that make 1756-xnb a given status table directly corresponds to the node address of a device. I to do not see a reset or config button on the card, just the switches to set baud rate and node address.
The scanner module then delivers a copy of these output values to modules on DeviceNet.

Posted 19 Oct Conor are you sure you have a DNB I have never come across this configuration button. For a Group 2 only device, this means that the device is not allocated to a master. Identifies information that is critical for successful application and understanding of the product. Enter a mznual list.
Manual 1756-dnb/e eds
A 01 N 33 E 72 The following table summarizes the codes. Check for disconnected cables.
The bit status register reflects the current state of several key module-level operational parameters. Inspect the slave devices and verify connections.
Make sure that scanner drop cable is providing network power to scanner communication port.
Anyway during the troubleshooting process the “Configuration button” was pushed a couple of times. Is there a way to “Disable” this button?? Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product.
No direct network traffic for scanner detected. We thought that there was a fault on the PLC. Try replacing slave device. The device has detected an error duplicate MAC ID or bus-off that has rendered it incapable of communicating on the network. The device is operating in a normal condition and is online with no connections established. Condition off green flashing green 1 1 Indicates Scanner is not online.
This industrial control equipment is intended 156-dnb operate in a Pollution Degree 2 environment, in overvoltage category II applications, as defined in IEC publication A at altitudes up to meters without derating. Electrostatic discharge can damage integrated manuual or semiconductors if you touch backplane connector pins. Scanner is in this mode when it Null Master Slave Dual contains an empty or disabled scan list out-of-box default. Scanner is initializing the DeviceNet network.
If your module is not connected to the network: The flash rate of the LED is approximately 1 flash per second.
When you insert or remove a module while backplane power is on, an electrical arc may occur. When not in use, keep the module in its static-shield bag. It has been removed since hardware series C, if I can remember well.
Check the network configuration. Select the network node address by pushing in and holding the pushbutton. It is one of two loops on the only ControlLogix that we have on-site.
Then we saw that the button was in fact mznual configuration button and not a reset button. Chassis Type Series B: Like other slaves, the scanner module exchanges data with only one master when it is in manul mode.
Scanner has failed to transmit a message.
