Animatics Combitronic™ Technology
Combitronic™ may coexist with either CANopen or DeviceNet protocols at the same time. Unlike these common protocols however, Combitronic™ requires no single dedicated primary to operate. Each Integrated Servo connected to the same network communicates on an equal footing, sharing all information, and therefore, sharing all processing resources. Combitronic communications operate over a standard “CAN” interface, the same basic hardware used in most automobiles as well as in familiar industrial networks such as CANopen and DeviceNet. Unlike these common control networks, however, Combitronic has no primary or follower.
An array of Animatics SmartMotor servos become one giant parallel-processing system when equipped with the Combitronic™ interface. This powerful technological advancement provides the joint benefits of centralized and distributed control while eliminating their respective historical drawbacks, opening up the possibility to either:
- Eliminate PLCs from machine designs
- Enhancing the performance of existing PLCs by unburdening it from specific tasks
The optional Combitronic™ technology allows any motor’s program to read from, write to, or control any other motor simply by tagging a local variable or command with the other motor’s CAN address. All SmartMotor™ units become one multi-tasking, data-sharing system without writing a single line of communications code or requiring detailed knowledge of the CAN protocol. The only prerequisite is to have matched baud rates and unique addresses.
Up to 120 SmartMotor servos may be addressed on a single array using Combitronic technology.
Combitronic™ Protocol Features
- 120 axis node count
- 1MHz Bandwidth
- No Primary required
- No scan list or node list set up required
- All Nodes have full read/write access to all other nodes
For example, SmartMotor servos use a single letter command to start a motion profile, so a line of code to start a motion profile would look like one of the following:
G ‘Issue Go in local motor
G:2 ‘Issue Go to motor 2
G:0 ‘Issue global Go to all networked motors
Additionally, comparisons or live polling and value comparisons may be made across the bus.

In the event that a PC or HMI is desired to control a large number of SmartMotor servos, but RS-232 is desired to save the cost of direct CANbus interfacing to the newtork, any SmartMotor may be used as primary access via RS-232 to all Combitronic motors on its network. The following demostrat 12 motors in a network where 4 SmartMotors are in a serial daisy chain over RS-232. Each of those 4 may have up to 119 motors on its Combitronic network.
The Controlling PC may freely access and control all motors via a single standard RS-232 serial port.
