2. Determine the DECimal remainder and set the LSD switch to its
corresponding HEX digit.
If these switches are instead
set to 126 (7EH) upon powerup, the unit will retrieve its
address from the internal
EEPROM, which is modified
via the Set Slave Address
command.
If these switches are set to
255 (FFH) upon power-up, this
will return the address in
EEPROM to 126 (7EH).
The address stored in the internal EEPROM is modified via the Set Slave
Address command. If the address switches are set to 126 (or 126 to 254)
upon power-up, the module will retrieve the last address stored within its
EEPROM (126 from the factory). With both the internal EEPROM and
external switch addresses set to 126, the unit will await the Set Slave
Address command after power-up, before proceeding to the
parameterization state (address 126 cannot be used in data exchange mode
and is reserved for commissioning purpose only). You must use the Set
Slave Address command to change the internal (EEPROM) address
following power-up in order to proceed. However, if the switches are set to
an address less than 126 upon power-up, then the switches determine the
slave address and the EEPROM setting is ignored. You can later restore the
internal EEPROM setting to 126 by powering the unit up with the address
switches set to 255 (FF). You would then power the unit up again with these
switches set to 126 in order to place the unit in commissioning mode.

Connect Earth Ground as shown in the connection drawings above.
Additionally, ground the ProfiBus cable as shown below.
Earth Ground
The ground connections noted are recommended for best results. If
sensors are already grounded, use caution and avoid making additional
ground connections which could create ground loops.
Warning: To comply with
safety and performance
standards, use shielded cable
and connect earth ground as
noted. Failure to use good
wiring and grounding practices
may be unsafe and hurt
performance.
The plastic module housing does not require earth ground.

TROUBLESHOOTING
Tips For Building
ProfiBus Networks
The module routinely performs internal diagnostics following power-up
or reset. During this period, the green “Run” LED will flash for a moment. If
the diagnostics complete OK, the “Run” LED will stop flashing after a few
seconds and remain ON. This indicates the unit is operating normally.
Once the unit has passed through the initialization, parameterization, and
configuration states, and is in data exchange mode, the yellow BUS LED will
be ON. If the BUS LED is OFF and the unit is connected to the network,
then this is indicative of an initialization problem.

Top Four Common
ProfiBus Problems
Troubleshooting Tools
Follow the ProfiBus installation guidelines.
Use the recommended cable and connectors of the standard.
Verify that none of the wires are broken or shorted.
Don’t mix the A & B lines. Use green wire for A and red wire for B.
Do not exceed the recommended segment length for the baud rate.
Make sure that there are no more than 32 RS-485 devices per
segment (including the master device and the repeater).
Check for proper termination of all copper-wire network segments
(an RS-485 segment must have a termination resistor at both ends
of the segment only).
All activated terminations must be powered all the time. If this is not
possible, then consider using an active-termination box.
Check whether the station address is set to the correct value.
If your network connects between buildings or runs through
hazardous environments, consider the use of fiber-optics.
Avoid drop lines and keep their length within the specified maximum.
For T-drops, consider using repeaters and active-bus terminations.
1. Incorrect slave address set at the slave.
2. ProfiBus connector between the master and slave has its
termination switch turned ON.
3. Incorrect module configuration sent to slave.
4. Configuration is based on outdated GSD file information.
There are several models of handheld devices on the market that
simplify the installation and troubleshooting of ProfiBus networks. The more
sophisticated units include LCD displays that read out errors directly. Two of
these of these devices are referenced below:

In general, these devices can be used to check the network wiring
before devices are connected to the bus and are often used to indicate:




Whether the A and B lines have been switched.
Whether a short exists between the A & B lines and shield.
The occurrence of a wire-break in the A or B line, or shield line.
Improper termination.

Troubleshooting Tools
Create a list of all stations connected to a network (useful for
identifying missing or “offline” devices).
Can test individual stations and help identify duplicate addresses.
Measure the distance along a network segment to verify whether it
complies with the Profibus requirements for distance and data rate.
Detect signal reflections along the network, useful for locating bus
line interruptions and discontinuities.
Acromag strongly suggests the use of these tools for building and
maintaining ProfiBus networks.
Note that Profichip also offers a Profibus connector (PA003100) that
includes 4 network diagnostic LED’s that may be helpful in trouble-shooting
your network (see table below).
The standard 9-pin ProfiBus connectors with integrated termination
resistors are also helpful in troubleshooting segments of the network. In
most of these connectors, when the termination resistors are switched ON,
the outgoing portion of the connector is disconnected. As such, you can
selectively disable segments of the network until you find the branch that is
causing the problem. For example, if your handheld unit is connected to the
beginning of a network and indicates a wire break, you can selectively switch
off portions of the network and recheck your handheld unit to help pin point
the portion of the network that is causing the problem. Below are some
ProfiBus connectors that we recommend:

___________________________________________________________________
These models have two I/O Configuration definitions in their GSD files,
one for normal operation, and another for accomplishing calibration. The
normal data exchange definition supports 12 input words (your measured
value). A second calibration definition supports 12 input and 12 output
words. The master software will allow you to choose which mode the slave
will assume—Input Mode or Configuration Mode. The method used to
transfer information between the master and slave will vary widely between
systems. The steps below represent the minimum steps necessary to
accomplish software calibration. If you choose to perform calibration and
select Configuration Mode, the master will download the 12I/12O
configuration during the startup sequence, and the module may then be
calibrated as follows:
11
CALIBRATION
Note: For best results, be sure to use a precision signal source capable of
reproducing the nominal endpoint signals at least as accurate as the module
itself (better than ±0.1% of span). Always allow the module to warm up a
few minutes prior to calibration.
1. With your master software, select the “Configuration Mode” from the
GSD file when setting up the master to communicate with the module.
2. With user parameterization bytes 0-2, set the ranges that are to be
calibrated.
3. Apply the zero calibration signal (see table below) to the input to be
calibrated and allow the input to settle a few seconds.
4. Write FFH into the low-order byte of the channel’s output word several
times (to ensure transmission). In Configuration Mode, the module will
automatically calibrate the channel’s zero value when FFH is detected.
Then write 00H into the low-order byte to complete zero calibration.
5. Apply the full-scale calibration signal (CalHi, see table) to the input to be
calibrated and allow the input to settle a few seconds.
6. Write FFH into the high-order byte of the channel’s output word several
times (to ensure transmission). In Configuration Mode, the module will
automatically calibrate the channel’s full-scale value when FFH is
detected. Then write 00H into the high-order byte to complete full-scale
calibration.
7. Repeat steps 3-6 for the other channels of the same range.
8. With user parameterization bytes 0-2, select the next range to be
calibrated.
Note (963PB): The 4-20mA range is calibrated when the 0-20mA range
is calibrated and is not calibrated separately. All other ranges are
calibrated separately.
9. Repeat steps 3-7 for all channels of this range.
10. Repeat steps 8-9 until all input ranges have been calibrated.
11. When finished calibrating, use the master software to return the module
to the normal “Input Mode” to prevent miscalibration.
After completing calibration, the module should be reconfigured as
required and placed in the normal “Input Mode” configuration (I/O
configuration is 12 input words only). In general, your software allows you to
select the normal “Input Mode” configuration, and the slave will then be
taken off-line by the master and reconfigured. If reconfiguration is
successful, the slave module will pass to the data exchange state with a
normal I/O configuration.

BusWorks® 963/964PB Module User’s Manual
ProfiBus Analog I/V Input
___________________________________________________________________
These input modules will interface with up to twelve analog input
channels of DC current or voltage according to the model number, and
provide an isolated RS485/ProfiBus interface for configuring and monitoring
the inputs. Input channels are arranged in three groups (ports) of four
inputs, which are driven to separate channels of the A/D. Because each port
feeds a different A/D channel, each channel of the port must have the same
input range. However, different ports may use different input ranges.
Current inputs sink into a precision 50Ω resistor (963PB). Voltage inputs
feed precision 10:1 resistive dividers (964PB). A multiplexer is used to
connect the voltage from each channel of a port to a channel of the A/D
converter (one A/D channel per port). The A/D converter then applies gain
to the signal, converts the analog signal to digital, and then digitally filters the
signal. The digitized signal is then transmitted serially to the microcontroller.
The microcontroller completes the transfer function according to the input
type and range per its embedded program. Configuration and calibration
parameters are stored in non-volatile memory integrated within the
microcontroller. These modules implement the ProfiBus protocol via an
industry-standard SPC3 ASIC from Siemens. This ASIC acts like a RAM or
UART chip to the internal microcontroller and completely handles the
requirements of the protocol standard. The ASIC will transfer network data
to the microcontroller and automatically provide the response to the bus.
The ASIC handles the ProfiBus protocol and communicates with the network
via an optically isolated RS485 transceiver. A wide input switching regulator
(isolated flyback) provides isolated power to the I/O circuit and the RS485
port. Refer to the simplified schematic shown below to gain a better
understanding of the circuit.

ProfiBus Analog I/V Input
__________________________________________________________________
SPECIFICATIONS
These DIN-rail mount, ProfiBus DP slave, input modules include twelve
analog input channels for DC current (963PB), or DC voltage (964PB), and
provide an isolated RS485/ProfiBus network interface. Units are DCpowered with reverse polarity protection. Analog inputs (as a group),
network, and power are isolated from each other. Input channels share
common. Non-volatile reprogrammable memory in the module stores
configuration and calibration information.
Model Numbers
963PB-2012 (Current)
964PB-2012 (Voltage)
The ProfiBus model prefix “900” denotes the Series 900. The “PB” suffix
denotes ProfiBus. Select 963PB for current input, and 964PB for voltage
input. The four digit suffix of this model number represents the following
options, respectively: “2” = ProfiBus DP; “0” = Default; “12” = 12 Channels.
Analog Inputs
Twelve analog input channels with a common (RTN) connection for DC
current or voltage applications only. The unit must be wired and configured
for the intended input type and range (see Connections Section for details).
The unit can be configured to accept one of several input ranges described
below.
DC Current (963PB Only): Configurable for 0 to 20mA, 4-20mA, 011.17mA, and 0-1mA DC nominal input ranges. A precision 49.9
current sink resistor converts the input current to a voltage that is
processed by the A/D converter. An optional external sensor is
required to monitor AC current signals (Acromag Model 5020-350).
This sensor generates a DC milliampere signal of 0 to 11.17mA for the
module (see Table 1 below for scaling to AC current).
Current Input Reference Test Conditions: 4 to 20mA current input;
Ambient Temperature = 25C.
Input Overvoltage Protection: Bipolar Transient Voltage Suppressers
(TVS), 5.6V clamp level typical.
Optional AC Current Sensor (Model 5020-350, For Use With
961PB/963PB): This sensor is a toroidal instrument transformer that
converts a sinusoidal 50-60Hz AC current signal into a low level DC
milliampere signal of 0 to 11.17mA. The input AC current range is a
function of the number of turns placed through the toroid as shown in
Table 1 below. This sensor is isolated and requires no calibration or
adjustment. When used with a 961PB/963PB module, it provides
redundant input isolation and may facilitate input-to-input isolation of
this six channel unit.

Parity: Even parity.
Stop Bits: One.
Communication Distance: Up to 1200 meters without a repeater.
Address: Set via two rotary hexadecimal switches adjacent to the power
terminals, or alternately via the Set Slave Address command. Valid
setting is 0-125 (7 bits). Address 126 (7EH) is the default factory
address and is reserved for commissioning purposes only. Address
127 (7FH) is reserved by the software as a global address for broadcast
messages. If the address switches are set to 126 upon power-up (or
126 to 254), then the unit will retrieve its address from its internal
EEPROM rather than the switches. The internal EEPROM setting is
modified via the Set Slave Address command. Powering up with
switches set to 255 (FFH) will cause the internal EEPROM setting to
revert back to 126 (7EH), which may be used to recommission the
module. If both the internal EEPROM address and the switches are set
to 126 upon power-up (this is the initial state from the factory), the
module will await the Set Slave Address command before completing
initialization and assuming the data exchange mode.
IMPORTANT (Address Setting): The internal EEPROM address
setting and external switch setting is 126 from the factory. As such, the
module will await the Set Slave Address command following power-up
and will not proceed to exchange data, unless the external switches are
instead set to an address from 0-125, or the internal setting is changed
to an address from 0-125 via the Set Slave Address command.
Maximum Message Size: Up to 32 bytes recommended, extendable up to
244 bytes of data/node/message, plus 11 bytes of overhead (frame).
ProfiBus Character: 11 bits (1 start bit + 8 data bits + 1 even parity bit + 1
stop bit). Applies to all bytes, including frame bytes.
Bus Idle State: “1” (a start bit causes line to go to “0”). An idle state of at
least 33 Tbits (sync-time) must be provided between messages.
Note: 1Tbit at 12Mbaud = 1/12000000bit/sec = 83nsec.
Ident_Number: 06F4 Hex (963PB-2012), 06F5 Hex (964PB-2012).
GSD File: ACRO06F4.GSD (963PB-2012), ACRO06F5.GSD (964PB2012).
Network Capacity: Multi-drop up to 31 modules, plus a host, without a
repeater. Up to 125 modules plus a host if four repeaters are used (one
for every 31 nodes).
Network Termination: Use 220Ω “A” to “B”, plus 390Ω “A” to GND, and
390Ω “B” to +5V. Use ±2%, 0.25W resistors.

LED Indicators:
Run (Green) - ON indicates power is on and unit is OK. Flashing
ON/OFF indicates unit is performing diagnostics (first few seconds
following power-up), or has failed diagnostics (after a few seconds).
Bus (Yellow) – ON indicates unit has completed its initialization
sequence and is in the data exchange mode on the network.
Switches:
Slave Address – Slave address is set via two rotary hexadecimal
switches adjacent to the power terminals (see Address above).

Note that channels of the
same port (every group of 4
channels) share the same
configuration, but the
configuration may vary port-toport. All parameterization
bytes take effect immediately.
This model does not include
any user defined diagnostic
data (Ext_Diag_Data).

Description
A 16-bit signed integer value with resolution of
0.005%/lsb. 20000 is used to represent 100%. For
example, -100%, 0% and +100% are represented by
decimal values –20000, 0, and 20000, respectively. The
full range is –163.84% (-32768 decimal) to +163.835%
(+32767 decimal).
A 16-bit signed integer value with resolution of 0.1C/lsb.
For example, a value of 12059 is equivalent to 1205.9C,
a value of –187 equals –18.7C. The maximum possible
temperature range is –3276.8C to +3276.7C.
A discrete value is generally indicated by a single bit of an
8-bit byte. The bit number/position typically corresponds
to the discrete channel number. Unless otherwise
defined for outputs, a 1 bit means the corresponding
output is closed or ON, a 0 bit means the output is open
or OFF. With active-high inputs, a value of 1 specifies
the input is in its high state (usually >> 0V), while 0
specifies the input is in its low state (near 0V). With
active-low inputs, a value of 1 means the input is ON
(Active low near 0V), while 0 specifies the input is OFF or
in its high state (usually >> 0V).
Data Types
I/O values of Acromag 9xxPB
modules are represented by
the simple data types shown at
left for temperature,
percentage, and discrete
on/off. Note that when
transferring words, data bytes
are transmitted using “Big
Endian” format (MSB first, LSB
second).
