Setting up the Adaptor I/O - Data In

Selects the parameters which will be made accessible for configuration/ writing from the 1560-MBP. As with the Data Out parameters, there are eight possible selections. These may be chosen by the programmer to meet the needs of the application.

Logic Control Word

Since the most common implementation of the 1560-MBP is with the variable speed drives, we have included the following table for the more commonly used control bits. This word should be verified in the A-B User Manual for the particular device being controlled.

Bit	Function	Description
0	Stop	1	= Stop, 0 = Not Stop
1	Start	1	= Start, 0 = Not Start
2	Jog	1	= Jog, 0 = Not Jog
3	Clear Faults	1	= Clear, 0 = Not Clear
4, 5	Direction	00	= No Command
		01	= Forward
		10	= Reverse
		11	= Hold Direction

Drive Status Word

Since the most common implementation of the 1560-MBP is with the variable speed drives, we have included the following table for the more commonly used Status bits. This word should be verified in the A-B User Manual for the particular device being monitored.

Bit	Function	Description
0	Enabled	1	= Enabled
1	Running	1	= Running
2	Cmd Direction	1	= Forward, 0 = Reverse
3	Actual Direction	1	= Forward, 0 = Reverse
4	Accel	1 = Accelerating
5	Decel	1	= Decellerating
6	Alarm	1 = Alarm Active
7	Fault	1 = Fault Active
8	At Speed	1 = At Speed
