Modbus gateway for industrial monitoring applications

AKCP’s family of sensor and control systems developed over the last 30 years are widely used in industrial applications. Anywhere you need to monitor sensors and control systems our network enabled devices are the first choice.

The sensorProbe+ series is a cost effective and robust solution that can act as a Modbus RTU <-> TCP/IP as well as Modbus RTU or TCP/IP <-> SNMP gateway. It can function as either Master or Slave through the addition of the optional Modbus EXP port on all SP2+ and SPX+ units.


SPX+ as Modbus Slave
SPX+ can poll over TCP or RS485 up to 32 values from Modbus Devices connected to your network
Connect to SPX+ using TCP/IP or RS485 and poll up to 150 sensor values to any Modbus register address
SPX+ as Modbus Master
Modbus Gateway is available on both the SPX+ and the SP2+ base units.

sensorProbeX+ (SPX+) comes in a variety of standard configurations to suit your monitoring needs. Additional modules can be added or a complete custom unit can be built so you get only the features you want. Add a Modbus EXP port to monitor third party Modbus devices.
