Redundant Power Supply ModuleGE Fanuc IC695PBM300 RX3i Profibus DP
Master module
Version 1.04 of the IC695PBM300 RX3i PROFIBUS Master resolves the
following issues:
- When multiple Lumberg devices (8in/4out) are connected to the bus
and power is removed from these devices, but the PBM300 remains
powered, the inputs assigned to the Lumberg devices will toggle
between 1 and 0.
- Configuring slaves with a large amount of parameter data returns
the correct error code when parameter data exceeds the available
memory space. The IC695PBM300 is field upgradable to firmware
version 1.04 using the firmware upgrade utility.

The PACSystems* RX3i PROFIBUS Master Module, IC695PBM300, allows
the host RX3i CPU
to send and receive data via a PROFIBUS-DP network.
The IC695PBM300 module provides the following PROFIBUS
communications features:
Supports all standard data rates
- Supports a maximum of 3,584 bytes of input data and 3,584 bytes of
output data
- Supports a maximum of 125 PROFIBUS-DP slaves
- Supports a maximum of 244 bytes of input data and 244 bytes of
output data for each
- slave
- Supports Sync and Freeze modes
- Supports DP-V1 Read, Write and Alarm messages
- Has PROFIBUS-compliant module and network status LEDs
The PROFIBUS Master module must be located in an RX3i Universal
Backplane and requires a host RX3i CPU with firmware version 2.9 or
later.
The PROFIBUS module receives its firmware upgrades indirectly via
the host controller CPU using the WinLoader software utility.
WinLoader is supplied with any updates to the
PROFIBUS module software.

Module Status Information
For details on using the Communication Request function to
communicate with the PROFIBUS master module, refer tothe PACSystems
RX3i PROFIBUS Modules User’s Manual, GFK-2301.
Slave Status Bit Array
The Slave Status bit array contains a bit for each slave. If
communication with a slave has no errors, the bitcorresponding to
the slave (determined by its network address) is set. If the
communication has errors or is not occurring for any reason, the
bit is cleared. The Master also maintains its own status in the bit
corresponding to its network address.
Slave Diagnostics ID Array
If diagnostics are pending, the first word of this two-word array
contains the station address of the first slave that has
diagnostics. The diagnostics can be read using the Get Device
Diagnostics COMMREQ (command 4). This clears the word and the
master then places the next pending diagnostic address into the
Slave Diagnostics word. If this word is zero there are no pending
diagnostics.The second word of this array is reserved and set to 0.
DPV1 Alarm Status Array
The 32-bit DPV1 Alarm Status array is used at the beginning of a
scan to receive the station address of a slave that has sent a DPV1
Alarm message. If another slave has sent a DPV1 alarm message, it
is ignored until the first one has been
serviced, and will then appear in a subsequent scan. For details on
the status format, refer to “DPV1 Alarm AcknowledgeCOMMREQ” in
GFK-2301.
Slave Configured Bits
This 128-bit array indicates which slaves on the PROFIBUS network
are configured. Each slave has a corresponding bit in this array. A
slave's configuration status address equals Start Address + Station
Address of the slave. For example, if the configuration status bits
are mapped to %I00001, the status for the slave at Station Address
5 would be found at %I00001 + 5=%I00006.
Slave Diagnostic Bits
This 128-bit array indicates which slaves on the PROFIBUS network
have diagnostic data available. The diagnostics can be read using
the Get Device Diagnostics COMMREQ (command 4). Each slave has a
corresponding bit in this array. A slave's diagnostic status
address equals Start Address + Station
Address of the slave. For example, if the configuration status bits
are mapped to %I00001, the status for the slave at Station Address
5 would be found at %I00001 + 5=%I00006.
Connecting the Module to the PROFIBUS Network
The module contains a standard female DB9 connector, labeled
“PROFIBUS,” that can be connected to a PROFIBUS busterminal that
complies with EN 50170.
The PROFIBUS module has no built-in termination. If termination is
required, you must use a bus terminal that has builtin selectable
termination
