Only real inputs and outputs are documented during address assignment.11 I/O address assignments are typically represented in one of three numbersystems: __________________, __________________, or __________________.12 The I/O address assignment table should closely follow the __________________.13 Using the circuit shown in Figure 3 and assuming that the PLC has a modularity of8 points per module, there are eight modules per rack, the master rack is numbered0, and the number system is octal:(a) circle all real inputs and outputs(b) assign the I/O addresses(c) draw the I/O connection diagramIndustrial Text & Video Company www.industrialtext.com 1-800-752-839856
