DescriptionThe SiNet Hub 444 allows up to 4 Stepper or Servo Si drives to be controlled in host mode from a single PC or PLC’s RS232 serial port or will run in stand-alone mode. Each indexer-drive acquires its unique address from the port to which it is connected. This simple addressing scheme minimizes the cost of the drives, and more importantly, the cost of configuring and/or replacing drives in your system. Connections are made with low cost, reliable RJ11 cabling. Any of our popular, cost effective programmable Stepper or Servo Si drives or Si motor controls can be used with the SiNet Hub 444. By choosing the power level and features you need for each axis of your application, SiNet can provide a cost effective single or multi-axis motion solution. The SiNet Hub 444 is powered by the drive that’s connected to port #1, saving you the cost and installation expense of using a separate power supply. Our Si Command Language (SCL) allows a host PC or PLC to execute relative, absolute and homing moves, make status inquiries, sample inputs, set outputs, and more. If your application requires a single axis to operate in "host mode", you can connect any of our programmable Si drives directly to your PC via the SiNet Hub 444 and invoke the Si Command Language (SCL). SCL allows for control via serial commands sent from a host device such as a PC or PLC. This permits the user to perform a variety of motion, I/O, and system status tasks in real time via a host serial device.
