Allocations Directly Related to Instructions
Address	Bits	Name	Function	Controlled by
A200	11	First Cycle Flag	ON for one cycle after FQM1 operation begins.	Module
	12	Step Flag	ON for one cycle when step execution is started with STEP(008).
A510 to	00 to 15	Macro Area Input Words	Before the subroutine specified in MCRO(099) is executed, the con-
A514			tents of the five words specified in the operand to be passed to the
			subroutine are stored here.
A515 to	00 to 15	Macro Area Output	After the subroutine specified in MCRO(099) has been executed, the
A519		Words	results of the subroutine are transferred to these five words.

Built-in I/O Allocations

The Coordinator Module and Motion Control Modules all have built-in I/O. The I/O Area allocations to the con- tacts on the Modules are given in the following tables.
