ValuPoint VP4-0610 Programmable I/O for Modbus RTU

Control Solutions’ Model VP4-0610 ValuPoint® Programmable I/O for Modbus RTU operates as a master or slave for I/O expansion, or as a controller with soft PLC capability. The VP4-0610 is a scaled down, low cost version of the VP4-2310 featuring 2 universal inputs that may be confi gured as analog or discrete, 2 dedicated discrete inputs, and 2 Form A relay outputs.

The ValuPoint® series of controllers is designed to be a building block in a distributed control system. The VP4-0610 can be used as Modbus slave for system expansion, or as Modbus master for stand-alone applications. When configured as Master, the VP4-0610 can query other Modbus devices, and use local registers to mirror mapped registers in remote devices.

All of the ValuPoint features available to local objects are also available to the remote mapped objects. This means the remote objects can be incorporated into the local i.CanDrawIt® program.

The VP4-0610 has a total of 320 data objects, of which the first several are assigned to physical I/O points. The remaining objects may be used as local storage for the soft PLC program, or may be used to mirror remote registers in other Modbus slaves. Each data object may be accessed as 16-bit or 32-bit integer, or floating point. Discrete points may be read as holding registers, coils, or discrete inputs. Analog points may be read as holding or input registers.

ValuPoint® support software, available for download at no cost, includes the VP4-0610 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.
