DF1 Master/Slave to HART Analog Gateway
5108-DFCM-HART
5128-DFCM-HART
Product Description
The HART Analog Input Gateway provides a clean way to integrate HART Analog instruments with existing controller platforms on a DF1 network. The gateway works well for field applications where it can be installed closer to HART instrument, saving on copper cable and installation costs. The gateway also saves valuable rack space for other in-chassis options. The gateways provide extremely fast channel update times (all channels updating simultaneously in 67 ms) making the HART Analog Input Gateway ideal for applications where high speeds and point-to-point connectivity are required. These gateways are available in 4 and 8 Analog input channel options.
The DF1 (DFCM) protocol driver supports Master or Slave implementations of the protocol on each DF1 port. All DF1 ports are individually configurable, providing a great deal of flexibility.
The HART Analog Protocol exists in 4 and 8 channel implementations. This driver can be configured on an individual channel basis to operate as a HART Master Station and supports all the available HART commands including Universal, Common Practice and Device Specific Commands. Each HART channel is independently configured to interface with the internal database in the module.
Product Applications
ProSoft Configuration Builder (PCB) provides a quick and easy way to manage module configuration files and view module and network diagnostics. PCB is not only a powerful solution for new configuration files, but also allows you to import information from previously installed (known working) configurations to new projects.
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration Data Area
This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.
DF1 Master/Slave Protocol Specifications
The DF1 Master/Slave Protocol driver provides extensive support for both Master and Slave implementations of the protocol. The serial port on the gateway is user-configurable to support the DF1 protocol (Master or Slave, Error Checking, Baud rate, etc).
