Configure Control Software for Modbus Plus Mode
The Series H control operating mode must be set to Serial to use the
Modbus Plus expansion board. There is no selection for Modbus Plus
on the Level 1 Input block Operating mode parameter list. However,
selecting Serial with the Modbus Plus expansion board installed will
allow operation of the Modbus Plus board.
Many commands in the Command Language can be used regardless of
the setting of the control’s Operating Mode parameter (such as
changing and viewing parameters). However, commands intended to
control the motor shaft require the control be in the Serial (Modbus Plus)
Mode.
Note: The firmware version of the Series H control must support the
Baldor Binary Protocol (BBP). To confirm that BBP is supported,
perform the following:
Scroll to the Level 2 Communications block, and view the
selections. If RS485BBP is available, the software version is
compatible with the Modbus Plus expansion board. Otherwise,
contact Baldor to obtain a software update.
During power up, the control checks if the communication board
is installed. If an RS485 board is installed, the RS485BBP
protocol is automatically selected during power up.
