The Allen-Bradley 1404-M505A-RIO module is a PowerMonitor module with 2 communication ports that include the RS-485 and Remote I/O ports. The Remote I/O port means that this PowerMonitor module can make use of both of its communication ports simultaneously. The port has various performance features including a 32-node capacity, a maximum cable length of 3048 meters (10,000 feet), 11 discrete inputs, 2 discrete outputs, a minimum rate of 50 milliseconds for block transfer updates, and a 5 milliseconds rate for discrete I/O updates. Also, it has 3 communication rate settings which are 230.4 Kbps, 115.2 Kbps, and 57.6 Kbps, data tables for all data access with read/write block transfers, and a quarter rack of slave devices.
The Allen-Bradley 1404-M505A-RIO module has a dual-port, thus allowing for the use of both the RS-485 and the Remote I/O communication ports concurrently. The RIO port has a logical quarter rack of I/O that requires the users to configure the last rack status, group number, rack number, and the communication rate. The parameters for the 1404-M505A-RIO module should be configured so that the RIO rack address in the scanner module is in the range of 0 to 63 decimal values and the default value is 1, and so that the RIO group number corresponds to the quarter rack in the range of 0, 2, 4, or 6 and the default value is 0. In the PLC-2 base system, set the RIO last rack to the highest-numbered group/lack on the channel in the range of 0 to 1 and the default setting is 0. Lastly, configure the Allen-Bradley 1404-M505A-RIO module's RIO communication rate to 230 Kbps, 115 Kbps, or 57.6 Kbps, and the default setting is 57.6 Kbps.
