Coordinator	• Peripheral port for connecting CX-Programmer and RS-232C port for connecting PTs and other
Module	devices
	• Ladder program for coordinating Motion Control Module data and other functions
	• 24 general-purpose I/O
	• 10 words of cyclic refresh data for each Motion Control Module allocated in Cyclic Refresh Bit Area,
	which is refreshed each Coordinator Module cycle
	• 4 synchronous data link words allocated for each Motion Control Module in Coordinator Module's Syn-
	chronous Data Link Bit Area, which is shared each Module cycle
Motion Control	• Linear Sensors, Servo Drivers, Inverters, etc., connected to special I/O
Modules	• Ladder program for executing motion control and other functions
	• 20 general-purpose I/O
	• 10 words of cyclic refresh data for each Motion Control Module allocated in its Cyclic Refresh Bit Area,
	which is refreshed each Coordinator Module cycle
	• 4 synchronous data link words allocated for each Motion Control Module in Coordinator Module's Syn-
	chronous Data Link Bit Area, which is shared each Module cycle
