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.

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.
