Chapter 22 Communicate with Modbus and Profibus Devices
Configure the Profibus DP Serial Port
You must either create a new project or open an existing project
before you can configure Profibus DP communication. Once the
software opens a project, it automatically displays the Hardware
Management window, from which you configure the Profibus port.
1. Right-click Protocols and choose New>Profibus dp Slave.
2. Expand Protocols, right-click the Profibus dp Slave icon, and
choose Properties.
Connect Signals
The Profibus DP Slave protocol lets you read data from the GuardPLC
controller and write data to the GuardPLC controller, but none of this
data can be used for safety functions.
For this field Specify
Station Address the address that uniquely identifies the Profibus dp slave on the network.
The station address must be less than or equal to 126.
Refresh Rate Refresh rate in ms for non-safe communication. The default is 0, the fastest refresh rate.
Interface the field bus interface to be used by the Profibus dp Slave protocol (comm1, comm2, comm3).
Choose comm1 for GuardPLC 1600 or 1800 controllers.
Baud Rate the data transfer speed in bits/s. Choose from a pull-down menu of predefined values between
300 and 115,200 bps. The default baud rate is 9600 bps.
