The ProtEX-MAX PD8-6080 and PD8-6081 Explosion-Proof Modbus Scanners can be programmed as a Master, Slave, or Snooper. Their primary use is to scan and display up to 16 Modbus registers or two 4-20 mA inputs in place of two Modbus registers.

In Master mode, the ProtEX-MAX reads up to 16 slave devices. In Snooper mode, the scanner listens to the Modbus traffic and picks up a specific register or registers being polled by a master device from a specific slave device and process the data being read.

In Slave mode, the scanner is controlled by a master device. In all modes, the data sent to the scanner is displayed, and used to operate the relays and 4-20 mA output.

The scanners are capable of polling up to 16 process variables (PVs) and displaying them in sequence at a user programmable scan rate.

A fully loaded ProtEX-MAX scanner comes with four SPDT relays, a 4-20 mA output, five digital inputs and four digital outputs, and RS-485 serial communications.

Free ScanView software allows the ProtEX-MAX Modbus Scanner to be accessed via a computer. It can be used to configure multiple scanners, conveniently monitor critical information, and data log right from a PC.
