PD865: Snooper Serial Input Modbus Digital Panel Meter
Expand the capability of other Modbus RTU serial devices with the new PD865 Snooper. It has a 6-digit sunlight readable display and may be set up as a master or slave. The PD865 comes with RS-485 communications, two relays standard, and up to four relays plus one 4-20 mA output.
Now, in addition to functioning as a Master or Slave device, the PD865 Modbus Serial Input Meter can function in Snooper mode. After some simple configuration a PD865 can be placed in Snooper mode where it is neither a Master nor a Slave. In this mode, the Snooper “listens” to Modbus traffic and “grabs” the data associated with a specific Modbus address and register number. It does this without detection by, or interfering with, the master or slaves on the network.
