Single-slot, in-rack solutions provide HART multi-drop communication for up to 60 instruments BAKERSFIELD, Calif., October 28, 2004ProSoft Technology’s HART (Highway Addressable Remote Transducer) multi-drop communication modules for Allen-Bradley’s ControlLogix, SLC 500, PLC5 and Schneider Electric’s Quantum processors allow networks to access temperature, pressure and multi-variable units. The HART multi-drop modules feature:• Multi-drop Field Network• Read / Write Data• 4 Channels / Module• 15 Transmitters / ChannelOther features include:• Supports available HART commands including Universal, Common Practice and Device Specific commands• Channels can be independently configured to read process variable data as well as configuration data from the instruments• User configuration of the module’s command list (up to 100 commands per channel) determines the HART commands issued on each channel to the instruments• Data read from the devices is made available to the processor across the backplane for use in control applicationsAuto polling automatically senses and determines devices on the channel, allowing easy setup and configuration for fast installation. The Burst communication mode enables 3 to 4 data updates per second. In Burst mode, the Master instructs the Slave device to continuously broadcast a standard HART reply message. The Master receives the message at the higher speed and instructs the Slave when to stop.The HART modules also allow two communicating Masters per channel. The primary and secondary Masters can be a PC, Handheld or DCS, offering a more flexible data access and robust control environment.ProSoft also offers Honeywell DE communication modules for the ControlLogix platform featuring:• Direct Connection to Honeywell DE Transmitters• Single and Multi-variable support• Supports up to 16 channelsHART and Honeywell DE communication is also available in the ProLinx line of DIN rail mounted, stand-alone gateways with connectivity to: • HART to Modbus (4107-MCM-HART)• HART (8 channel) to Modbus (4127-MCM-HART2)• HART to DF1 (4107-DFCM-HART)• HART to Modbus TCP/IP (4207-MNET-HART)• Honeywell DE to Modbus (4106-MCM-DEM)• Honeywell DE to DF1 (4106-DFCM-DEM)• Honeywell DE to Modbus TCP/IP (4206-MNET-DEM)
