Product Description:

The name of the tag will reflect the name you assigned the earlier. The "C" sub-group contains the contents of the configuration assembly, which is not currently used in the 1203-CN1. The "O" subgroup contains one entry for each word of output data you configured, and the "I" sub-group contains one entry for each word of input data you configured. The "O" sub-group corresponds directly to output data for a PLC-5 described on page 5-2 of the 1203-CN1 user manual (i.e., for most common configurations, word 0 is the logic command, word 1 is the speed reference, words 2 and 3 are the first pair of data links, etc.). The "I" sub-group is similar to the input data for a PLC-5, except that it is shifted by two words (i.e., word 2 is the logic status, word 3 is the speed feedback, etc.). Words 0 and 1 of the "I" sub-group represent network status data sent by the 1203-CN1 but not processed directly by the ControlLogix processor. At this point, I/O between the ControlLogix processor and the 1203-CN1 should be configured and running, and the meaning of the various I/O words should be understood. If you need further assistance in configuring I/O, please contact technical support.

Product's Character:

All drives come equipped with a fault LED. When the fault LED is illuminated it is an indication a fault condition exists. Refer to page 2-3 for the location of the fault LED. Once the fault is properly cleared the LED will return to an off state. Diagnostics As can be seen in Figure 2.3, there are two indicators provided to display the drive’s status condition. The DC Bus Charge Indicator is a neon bulb that will be illuminated when power is applied to the drive. The Fault Indicator is an LED that will be illuminated if a drive fault condition exists. Refer to details on How To Clear a Fault, below.How To Clear a Fault Important:Resetting a fault will not correct the cause of the fault condition. Corrective action must be taken prior to resetting the fault. To clear a fault perform one of the following:Cycle power to the drive. Cycle the stop signal to the drive. Cycle the [Clear Fault] parameter.
