We did a bit of investigation and found that the node of the scanner card had been changed, from 0 to 2. Firmware major revision 01 through 2.
The LED should be on for approximately 0. For a Group 2 only device, this means that the device is not allocated to a master.
Is there a way to “Disable” this button?? Follow these guidelines when you manuap the module: Anyway, we changed out a compact block that was faulty. Each product is supplied with markings on the 1756-dnh nameplate indicating the hazardous location temperature code.
The flash rate of the LED is approximately 1 flash per second. Warning and Attention statements help you to: When not in use, keep the module in its static-shield bag. Scanner is in IDLE mode, outputs are not under control, and inputs are being consumed.
With a network connection it displays the MAC ID or network node address, allowing you to select the node address for your module. Make sure the module properly connects to the chassis backplane.
Its a pity you didnt specify your harware more clearly. Make sure that module drop cable is providing network power to module comm. Electrostatic discharge can damage integrated circuits or semiconductors if you touch backplane connector pins. It does this by allowing the scanner to perform as a slave 1756-dnnb to another master on the network.
The output structure consists of a bit command register and a variable size bit array of up to words for output data. Posted 19 Oct edited. Hi guys, Manul had an issue today where we were getting comm’s errors on one of our DeviceNet loops. Anyway during the troubleshooting process the “Configuration button” was pushed a couple of times.
Identifies information that is critical for successful application mnual understanding of the product. Combinations of equipment in your mxnual are subject to investigation by the local Authority Having Jurisdiction at the time of installation.
Like other slaves, the scanner module exchanges data with only one master when it is in slave mode. The input structure consists of these data elements. Without a network connection it displays baud rates, allowing you to select the rate for your module. Make sure that scanner drop cable is providing network power to scanner communication port.
Check device configuration and slave node status.
Posted 25 Oct Release the button when the address number shown on the display is the number you want to select. Select the network baud rate by pushing and holding the pushbutton. Slave device is returning error responses when 1756d-nb attempts to communicate with it node number alternately flashes.
If your module is not connected to the network: Scanner has failed to transmit a message. An electrical arc can cause personal injury or property damage by: Scanner is in this mode when it Null Master Slave Dual contains an empty or disabled scan list out-of-box default.
If available, use a static-safe work station. It is one of two loops on the only ControlLogix that we have on-site.
The scanner module then delivers a copy of these output values to modules on DeviceNet.
