Technical Magnetek s Radio Drive Serial Interface is designed to communicate via a serial interface to directly control Magnetek s IMPULSE G+/VG+ Series 3 and IMPULSE G+ Mini Adjustable Frequency Crane Controls (consult factory for compatibility if you have an existing RDSI setup with a Series 2 drive). COMMUNICATION RDSI uses the Modbus RTU protocol over RS-485 to communicate between the radio receiver and the drive. This permits the receiver to serially command the drive. The receiver also has the ability to query the drive for feedback and present this to the user on the display of the transmitter. The RS-485 communication path is a multipoint communication while utilizing a four wire setup with TxD+, TxD-, RxD+, and RxD- for half duplex operation. The receiver communication card of the receiver has the ability to communicate directly with two drives. This means for every two drives a communication card is required on the Flex M. GETTING FEEDBACK Drive feedback is displayed on the display screen of the transmitter. If the transmitter does not have a display screen, the feedback option is not available. During normal operation, the display on the transmitter shows the command confirmation of how the transmitter is actively commanding the receiver to operate. The transmitter has a switch which permits for switching to the feedback screens for each drive. Feedback data from each drive is shown synchronously as each screen is cycled through. Upon changing to a new drive screen, the transmitter sends a message to the receiver querying it for the drive information. The receiver then queries the drive for the information and sends the data back to the transmitter where the data is shown on the display screen for the user. Faults and alarms from the drives are always shown asynchronously. These parameters are queried from the drive within 1000ms and are continually sent to the transmitter. HOW FEEDBACK IS DISPLAYED All of the feedback from the drives is shown on the display of the transmitter. The top line of the display always shows any faults and/or alarms regardless of which screen is being shown. If there are multiple faults and/or alarms, these are cycled through every 2 seconds. On the drive feedback screens, there are five lines of drive feedback parameters which are shown.
