Single Unit Slave System During normal operations, the ServoSensor™ communicates serially with the host computer in time frames based on the baud rate. The host computer monitors status and position information sent by the unit.
When a new target is necessary, a target and velocity command is sent one time. If target is acknowledged we return to reading position and status.
An operator interface would be connected to some form of input/output device installed locally in the computer or externally.
Multi-Unit Slave System A multiple slave system is integrated similar to a single slave system, except ServoSensors™ are installed on an RS-485 two-wire network. A host computer requires an RS-485 interface. An RS-485 card can be used. New PLC modules loaded with translator software also can be used for multiple axes. Address loading of the ServoSensor™ on a network would be required and would be accomplished using program software.
Discrete Control Inputs The ServoSensor™ Controller has three independent discrete +24 Vdc inputs for control of the servo loop. One input is called the set enable, one is called controlled device power and the third is called trigger.
Discrete Control Output The discrete output is a 24 Vdc signal that is programmed to act differently in two modes. With the first mode, the output will come on when a set is achieved and within a target window specified in the program. The second mode is used with the cycle program mode. When a cycle is complete the output will come on.
Probe lengths are available in one inch (1") to sixty-five inches (65.0"). For longer lengths consult the factory. Probes are available in inches or millimeters.
