Question

1 The figure below represents an output status file. In the column at the far right ist the address if there were output modules in the folowing slots on the PLC chassis: 2,5,6 1514113 12111 1019 8 7 6 |5 4 3 12 1 0Aodr. The figure below represents a input status file for a PLC. In the column on the far right enter the address if there were input modules in the folowing slots of the PLC chassis: 1, 3,4,5 1514113 12111 1019 8 7 6 I5 4 3 12 1 0Addr. 3.)The following memory map shows a bit file for a typical PLC. Determine the value of the bit contained in the given addresses 0 0 B3156 O B316 00 B3162 a.) B315812 b.) B3158/9 c.) B3 15815 d.) B31590 e.) B3160/2 ) Bit 14 element 157 g) Bit3 element 158 The data type identifier for integer values in Allen-Bradley PLCs is

List the address assuming one output module

Address	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
O:2.0/8	1	1	1	0	0	1	0	1	0	0	1	1	0	1	1	0
O:5.0/3	0	0	1	1	1	0	1	0	1	1	1	0	1	1	1	1
O:6.0/12	1	1	1	1	1	0	1	1	0	0	0	0	1	1	0	1

Table(1): Output status file

• The column on the left represents the module address.
• The top row represents the bits from 0 to 15 from right to left.
• Assume one output module from slot two,five and six.
• The address of the output module in the output status file is shown in Table(1).

From Table(1):

• The address for the selected output module in slot two is O:2.0/8.
• The address for the selected output module in slot five is O:5.0/3.
• The address for the selected output module in slot six is O:6.0/12.
