MODBUS RTU Interface
How to set the right NODE ID inside the motor configuration
Using NILAB Starter, connect to the single motor and store a different address in the Motor Parameter window. Then press Download configuration to the motor and Store configuration to Flash to permanently store the node id inside the memory of the motor.
Please use NODE ID starting from 1 to 128. The new node ID will be updated after a new power cycle.
How to connect the motors on the BUS
The NLi integrated miniature linear motors are equipped with MODBUS RTU communication interface.
More information about this type of fieldbus can be read here: https://en.wikipedia.org/wiki/Modbus
As in the schema above, for long connections we suggest using a terminal resistor of 120 ohm.
If the motor is used with the NL-DB15-MG6 terminal block from NILAB, please connect earth to ground, all grounds present must be connected together when the cable length is more than 5 meters.
This connection ensures the shielding of the cable.
Please note that you can read a maximum of 2 registers per read operation with standard communication speed of 38400 and parity Even. The MODBUS parameters are organized in different areas depending on the function involved.
How to scan the bus looking for motors
It is possible to scan the modbus using the NILAB Starter function call: SCAN MODBUS NODES Please, uncheck Get periodically status update checkbox. Then, check Avoid download parameter from drive checkbox, Connect to the right COM port using CONNECT to MOTOR button and then press SCAN MODBUS NODES button to scan the bus looking for the motors.
Standard Device for MODBUS Communication with NLi integrated motor
TOP7 PLC Touch
For the programming, diagnostics and parameterization of the integrated miniature linear motor, it is possible to use the TOP7 touch panel. NILAB provides a solution with software running on this device for use in industrial automation. Info about TOP7 are available here: http://www.elcoelettronica.it/en/products/products_view.php?name=TOP%207
Helmholz 600-400-7BA31 module
In combination with FCT640 PLC Master controller, it is possible to use this MODBUS RTU interface to communicate with the integrated drive miniature linear motor using a standard CODESYS program.
