Control Solutions’ Model VP4-2810 ValuPoint® Programmable I/O for Modbus RTU is a network I/O device that includes programmable control. The 4th generation ValuPoint® platform is designed to be a building block in a distributed control system where controllers communicate via Modbus RTU.

The ValuPoint® Model VP4-2810 features 12 discrete inputs configurable as dry contact closure to ground, or DC voltage sensing (in two groups of 6).

Pulse input at up to 1kHz is available on 2 channels. Pulse input to 10Hz is available on all channels. Pulse counts are totalizing, and saved to non-volatile memory every 15 minutes.

ValuPoint® support software, available for download at no cost, includes the VP4-2810 configuration tool, i.CanDrawIt graphical programming tool, and the pliWrite line programming tool. Both programming tools support both simulated execution and live debug. The tools connect via Modbus RTU.

The ValuPoint VP4-2810 Configuration Tool is a user friendly configuration tool that provides simple templates for reading and writing the Modbus registers that configure the device. Connect the ValuPoint to your laptop via any RS-485 adapter on your PC's COM port. .

i.CanDrawIt® is included at no additional cost with every ValuPoint® controller from Control Solutions. i.CanDrawIt® works just like an electrical schematic CAD program, except you draw control programs that look like circuits. The resulting software will function like the circuit you draw. i.CanDrawIt® includes visual program simulation as well as visual live debugging where supported by the target device. Set breakpoints or step through the program one visual function block at a time. Update variables and I/O objects in simulation or live.
