FMU Technical Manual
1.1 Fieldbus Master Units (FMU)
Fieldbus Master Units (FMU) are used together with the programmable controllers FP2/FP2SH
and FPΣ. By exchanging the FMU, you can connect to various networking systems.
FMUs are currently available for three bus systems: PROFIBUS, DeviceNet and CANopen.
Others are planned for the future.

Software
Make sure you use at least version 5.3 of FPWIN Pro, into which the functions necessary for
programming the FP-FMU blocks are integrated. You will require the add-on software "Control
Configurator FM" (part no. AFPS35510) for Control FPWIN Pro in order to configure the fieldbus
master units.
You can download convenient function blocks for Control FPWIN Pro to help you program the
FMUs free of charge from the Panasonic Electric Works Europe AG Web site:

1.2 Expansion Restrictions and Current Limitations
1.2 Expansion Restrictions and Current Limitations
1.2.1 Expansion Restrictions for the FP2 FMU
The number of FP2-FMUs is restricted by the size of the FP2 backplane.
1.2.2 Expansion Restrictions for the FPΣ FMU
The FPΣ FMUs are connected to the left side of the control unit via the FPΣ expansion
connector. Up to 2 expansion units can be connected to the left side of the control unit.
1.2.3 Limitations on Current Consumption
The 5V DC power used to drive the internal circuit of each unit is supplied from the power supply
unit of the FP2 through the internal bus of the backplane or from the FPΣ control unit through the
expansion connector.
Pay attention to the combination of units so that the rated capacity of the power supply is not
exceeded.

2.3 FP-FMU LEDs and Connectors
Various FP Fieldbus Master Units (FMUs) are available to meet your networking needs.
LEDs
Two dual-color LEDs give you a quick overview of the FMU's status at a glance:
• SYS (for DeviceNET MNS). Defines the general status of the FMU. For the hardware,
yellow means the self-test has been passed and the firmware loaded. Green is used for
application oriented functions such as valid configuration loaded.
• COM. Shows communication errors or status and communication activities. See
subsequent sections for details.
