PORT Status Indicator

Status	Cause	Corrective Action
Off	The adapter is not powered or is not connected properly to the drive.	• Securely connect the adapter to the drive using the Internal Interface (ribbon) cable. • Apply power to the drive.
Flashing Red	The adapter is not receiving a ping message from the drive.	• Verify that cables are securely connected. • Cycle power to the drive.
Solid Red	The drive has refused an I/O connection from the adapter. Another DSI peripheral is using the same DSI port as the adapter.	Important: Cycle power to the product after making the following correction: • Verify that all DSI cables are securely connected and not damaged. Replace cables if necessary. • Check the Events, replace the adapter with a compatible A-B branded product (22-COMM-P)
Flashing Green	Not Used.	Not Used.
Solid Green	The adapter is properly connected and is communicating with the drive.	No action required.
Solid Orange	The adapter is booting.	Wait until boot program has finished.
Flashing Orange	The adapter is in flash mode (SW8 down). Possible application failure.	• Wait until Firmware Update has been finished, then switch SW8 to 1. • Download Application code

MOD Status Indicator

Status	Cause	Corrective Action
Off	The adapter is not powered.	• Securely connect the adapter to the drive using the Internal Interface (ribbon) cable. • Apply power to the drive.
Flashing Red	The adapter has faults or a drive is missing in Multi Drive mode.	• Clear faults in the drive. • Disconnect additional DSI peripheral and cycle power to the drive. • If cycling power does not correct the problem, the parameter settings may have been corrupted. Reset defaults and reconfigure the module. • If resetting defaults does not correct the problem, flash the adapter with the latest firmware release. • For Multi-Drive mode, determine which drive is missing or faulted. Check cabling and configuration settings (see Configuring the RS-485 (DSI) Network section in Chapter 7 of the manual).
Solid Red	The adapter has failed the hardware test.	• Cycle power to the drive. • Replace the adapter.
Flashing Green	The adapter is operational, but is not transferring I/O data.	• Place the scanner in RUN mode. • Program the controller to recognize and transmit I/O to the adapter. • Configure the adapter for the program in the controller. • Normal behavior if no DSI I/O is enabled.
Solid Green	The adapter is operational and transferring I/O data.	No Action.

Off	The adapter is not powered or is not connected properly to the network or the Node Address is wrong.	• Securely connect the adapter to the drive using the Internal Interface cable and to the network using a Profibus cable. (Screw D-shell to the adapter). • Check the SW8 of DIP-Switches and set it to one - Normal operating state. • Check the DIP-Switches (SW1~SW7) node address and the Scanner setting. • Apply power to the drive.
Flashing Red	Error in Profibus configuration.	• Re-configure the Profibus module.
