What communications are available for the ATV900 series Process drives?

Issue:
What communications are available for the ATV900 series Process drives?

Product line:
Altivar process 900, 930, 950. 960, 980

Environment:
all

Cause:
n/a

Resolution:
The ATV900 series drives comes standard with 4x RJ45 communication ports.  2 port is Ethernet IP/Modbus TCP, 2 ports are Modbus serial.

Integrated Communication Protocols​
  • EtherNet/IP and Modbus TCP
    • Dual port EtherNet/IP adapter including standard CIP objects (AC/DC drive objects, CIP energy objects, etc.), compliant to ODVA specification.
    • The RSTP connection allows ring topology to help ensure continuity of service.
    • Dual port allows daisy chain connection to simplify cabling and network infrastructure (no need to use a switch).
    • Modbus TCP message handling is based on the Modbus protocol and is used to exchange process data with other network devices (e.g., a PLC). It provides
    • Altivar Process drives with access to the Modbus protocol and to the high performance of the Ethernet network, which is the communication standard for numerous devices.
    • SNMP (Simple Network Management Protocol) offers standard diagnostics services for network management tools.
    • The FDR (Fast Device Replacement) service allows automatic reconfiguration of a new device installed to replace an existing device.
    • Device security is reinforced by disabling some unused services as well as managing a list of authorized devices.
    • Setup and adjustment tools (SoMove, Unity with DTM) can be connected locally or remotely.
    • The embedded Web server is used to display operating data and dashboards as well as to configure and diagnose system elements from any web browser.
  • Serial port
    • Field network operation for exchanging data with other devices via the Modbus protocol
    • Multi-drop connection of the following HMIs and configuration tools:
      • The graphic display terminal supplied with the drive
      • A Magelis industrial HMI terminal
      • A PC with SoMove or Unity setup software

Optional Fieldbus Modules

The Altivar Process drive can also be connected to other industrial fieldbuses and networks by using one of the fieldbus modules available as an option. Fieldbus modules are supplied in “cassette” format for ease of mounting/removal.
Dedicated fieldbus modules:
  • CANopen:
    • RJ45 Daisy Chain
    • Sub-D
    • Screw terminal block
  • EtherCAT
  • PROFINET
  • PROFIBUS DP V1
  • DeviceNet
PROFINET and PROFIBUS DP V1 modules also support the Profidrive and CiA402 profiles.

It is possible to maintain communication using a separate power supply for the control and power sections. Monitoring and diagnostics via the network are possible even if there is no power supplied to the power section.

Additional Notes:
  • Altivar Process drives can only take one fieldbus module, in slot A only.
  • They cannot take 2 modules of the same type (e.g., 2 digital and analog I/O modules or 2 relay output modules).
  • The drives can take one digital and analog I/O module and one relay output module in either slot A or slot B.
