Modbus Scanner

Modbus Scanner
Precision Digital manufactures a fully featured line of Modbus® RTU scanners which can operate in Master, Slave, and Snooper (Packet Sniffer) mode. They are available in panel, field-mount, and explosion-proof varieties and can accept up to 16 process variables over their included RS485 input/output module. Some of these scanners have unique features such as a segmented bar graph and feet & inches displays for easy-to-understand level measurement.

Modbus Scanner

  • The ProVu PD6080 Super Snooper Modbus® scanner is a multi-purpose display and controller capable of scanning up to 16 Modbus process variables and accepts two analog process inputs. The scanner can be programmed as a Modbus RTU master, slave, or snooper. It is the ideal display for Modbus multivariable transmitters or for existing Modbus networks with transmitters in need of an easy-to-read and conveniently located remote display. As a master, the PD6080 can read up to 16 Modbus registers on up to 16 Modbus devices and automatically alternate each of these process variables (PVs) on the dual-line display along with a unit and tag for each. In snooper mode, the PD6080 can read any Modbus variable being polled by a master, which allows you to easily add a display into an existing Modbus network. Like all ProVu meters, the PD6080 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. Powerful math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio.

    Why you should buy:
  • The ProVu PD6081 Super Snooper feet & inches Modbus® scanner displays level information on a specially designed feet & inches display, instead of the usual decimal format. It is the ideal display for Modbus level or multivariable transmitters and is capable of scanning up to 16 Modbus process variables. Its unique feet & inches upper LED display can indicate up to 99 feet, 11 and 15/16 inches. The 6-digit lower display can indicate units, tags, or other variables such as volume, temperature, or density. The PD6081 also has dual analog inputs, for integrating traditional 4-20 mA or voltage inputs in the display scanning. The PD6081 can be setup as a Modbus master, slave, or snooper. Like all ProVu meters, the PD6081 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. Various math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio.

  • The ProVu PD6088 Super Snooper Modbus® scanner displays up to 16 Modbus process variables (PVs) on the bus using its RS-485 serial input. The PD6088 can function as a Modbus master, slave, or snooper. As a Modbus master, the PD6088 can poll multiple Modbus devices for up to 16 Modbus process variables. As a slave, a Modbus master can write up to 16 PVs to the scanner for display. In snooper mode, it can sit anywhere on the Modbus network and display up to 16 PVs being polled on the bus. When connecting a scanner in snooper mode, no other Modbus devices on the network need to be reconfigured, making it easy to add additional local or remote displays to a Modbus network. Like all ProVu meters, the PD6088 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. Various math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio.

  • The Snooper PD865 is an 1/8 DIN Modbus® meter that can be programmed as a Modbus® RTU master, slave or snooper. In snooper mode, the PD865 listens to the Modbus traffic and displays a process variable being transmitted on the bus. As a master, the Snooper can read up to 8 Modbus variables; it will display one and make the other variables available for other Snoopers to display in snooper mode. As a slave, a Modbus variable may be written to the PD865 by a Modbus master. The PD865 is available with two (2) relays, 4-20 mA analog output, and multi-pump alternation control.

  • The Vantageview PD6730X is a plastic, field-mounted, RS485 serial input Modbus® RTU scanner capable of scanning up to 16 Modbus variables and displaying them on an easy-to-read, dual-line, LCD display. It can be programmed as a Modbus RTU master, slave, or snooper. The PD6730X is available in two upper display line configurations: 5-digit decimal display and feet & inches display with bar graph. The lower line is the same for both versions and consists of seven alphanumeric characters. Two features that really make the PD6730X stand out are its wide viewing angle display and SafeTouch® through-window buttons. These buttons allow the PD6730X to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.

  • Go with the Helios PD2-6080 when you have multiple, (up to 16), Modbus registers you want to display on a single large display meter. The PD2-6080 can also accept two 4-20 mA signals. The PD2-6080 can be programmed as a Modbus RTU Master, Slave or Snooper allowing it to work in just about any Modbus application. Typically, the upper line displays the PV and the lower line displays the tag.

  • Go with the Helios PD2-6081 when you have a level application involving Modbus signals and you prefer to display in feet and inches instead of the more common decimal format. The PD2-6081 can display up to 16 modbus registers so a typical application might be 16 tank levels, 8 tank levels and 8 interface levels, or 5 tank levels, 5 interface levels and 5 temperatures. The PD2-6081 makes a great outdoor tank side indicator because its display is bright enough to read in direct sunlight and it will operate from -40 to 150°F.
