Using a DeviceNet Tool

However, because there are a variety of DeviceNet tools available, this chapter does not provide detailed information for using any one tool. For detailed information on your DeviceNet tool, see the documentation supplied with the tool.
5.2Connecting to the Model 2400S DN transmitter
To connect to the Model 2400S DN transmitter:
1.Default connection values for this transmitter are as follows:
•DeviceNet node address = 63
•Baud rate = 125 kBaud
If required, use the digital communications hardware switches on the device to set the DeviceNet node address and baud rate for this transmitter. To do this, see Sections 8.10.1 and 8.10.2.
2.Connect to the network where the transmitter is installed.
3.Using the same methods that you use for other DeviceNet devices, establish a connection to the Model 2400S DN transmitter, using the appropriate node address and baud rate.
5.3Using the DeviceNet device profile
All DeviceNet devices employ a device profile with an
In general, process and configuration data is stored in attributes, and operational functions are performed by using services or setting attributes to specific values.
Two standard services are used to read or write single attributes:
•The Get Single Attribute service (0x0E) performs an explicit read and returns a single value from the transmitter.
•The Set Single Attribute service (0x10) performs an explicit write and writes a single value to the transmitter.
In this manual, these two services are referenced as the Get and Set services.
Other services are used to reset values to 0, start or stop calibrations, to acknowledge alarms, etc. These services are identified by name and by service code (a hexadecimal label).
Input assemblies are used to publish multiple values to the DeviceNet bus. A summary of the input assemblies is provided in Table
