PROFIBUS DP Communication Architecture
The SST-PB3-VME-1 provides a single PROFIBUS DP channel through an RS-485 physical interface. The card supports DP-V0 and DP-V1 operation, including Master Class 1, Master Class 2, and Slave functions.
An onboard communications processor handles PROFIBUS protocol execution independently of the VME host processor. Dual-port RAM provides the host-side data exchange mechanism between application software and the communication processor.
The interface supports network rates from 9.6 kbps through 12 Mbps with automatic baud-rate detection. Diagnostic LEDs provide local indication of module status, PROFIBUS network status, and communication activity.
For VME-based control architectures, the card operates as an in-chassis communication interface while the host system accesses process data through the VMEbus memory interface.
Frequently Asked Questions (FAQ)
Q: How many PROFIBUS communication channels does the SST-PB3-VME-1 provide?
A: The supplied specifications identify one PROFIBUS channel using a DB-9 female RS-485 interface.
Q: Does the card require the VME host CPU to execute the PROFIBUS protocol?
A: No. An onboard communications processor performs protocol execution, while dual-port RAM transfers communication data to the VME host.
Q: Which PROFIBUS operating modes are supported?
A: The supplied data specifies PROFIBUS DP-V0 and DP-V1 operation with Master Class 1, Master Class 2, and Slave modes.
Field Installation Guidelines
Install the card in the designated VMEbus slot and verify mechanical engagement before applying system power.
Connect the PROFIBUS network through the specified DB-9 RS-485 interface using appropriate PROFIBUS-rated cabling and connectors.
Maintain separation between PROFIBUS communication wiring and high-current power, motor, and switching circuits to reduce electromagnetic interference.
Terminate and bias the PROFIBUS segment according to the network topology and connector termination requirements. Do not introduce unintended termination at intermediate devices.
Route communication cable shields continuously through compatible connectors and bond shielding according to the cabinet grounding design.
Verify VMEbus seating, connector condition, network polarity, cable shielding, and termination before commissioning communication.
Confirm that the configured PROFIBUS baud rate and master/slave role correspond with the host application and connected field devices.
