Coordinator
Module • Peripheral port for connecting CX-Programmer and RS-232C port for connecting PTs and other
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
Modules • Linear Sensors, Servo Drivers, Inverters, etc., connected to special I/O
• 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
