Introduction 1
About This Manual
This manual provides information needed to install
and use the Rice Lake Weighing Systems ProÞbus
¨
Indicator Interface. The ProÞbus Indicator Interface
allows IQ plus
¨
800/810 and IQ plus 310A indicators
to communicate with a ProÞbus master device using
the ProÞbus-DP communications standard.
1
The ProÞbus Indicator Interface is housed inside the
NEMA 4X stainless steel indicator enclosure to
permit use in washdown environments.
This manual applies to the following software
versions:
¥ ProÞbus Indicator Interface, Version 1.0
¥ IQ plus 800/810, Version 3.1
¥ IQ plus 310A, Version 5.0
Some procedures described in this
manual require work inside the indicator
or Profibus Indicator Interface
enclosure. These procedures are to be
performed by qualified service
personnel only.
Authorized distributors and their employees
can view or download this manual from the
Rice Lake Weighing Systems distributor site
at
www.rlws.com
.
1.0 Introduction
The ProÞbus Indicator Interface provides full control of indicator functions to the PLC programmer and allows
indicator weight and status data to be returned to the ProÞbus DP network. A diskette containing the GSD Þle
used to conÞgure the master device is supplied with the ProÞbus Indicator Interface (see Section 4.2 on page 16).
The following Þgure shows an example of the ProÞbus Indicator Interface used to connect an IQ plus 800/810
indicator to the master device on a ProÞbus DP network.
The ProÞbus Indicator Interface supports two sets of commands: 20-bit integer commands and 32-bit ßoating
point commands (see Section 3.0 on page 8). Both sets are designed for use in demand mode: the master device
sends a command to the ProÞbus Indicator Interface to request information from or pass data to the indicator; the
indicator responds with weight data, status information, or an acknowledgement that the command was executed.
For applications that do not require the capablilities provided by these commands, the ProÞbus Indicator
Interface can be used with the indicator in stream mode. In stream mode, the Display Status command provides
fast, continuous acquisition of indicator weight and status data.

2.1.1 Serial Communications Jumpers
Two jumpers, labeled
RxD
and
OUTPUT
, determine
whether the ProÞbus Indicator Interface uses RS-232
or 20 mA current loop for serial communications with
the indicator. Leave the jumpers in the position shown
in Figure 2-4 for RS-232 communications; move both
jumpers to the
20mA
position if using the 20 mA
current loop option. See Figure 2-2 on page 2 for
board location of the jumpers.
Figure 2-3. RxD and OUTPUT Jumpers, Showing Jumper
Positions for RS-232 Communications
2.1.2 Serial Connections
Serial communications connections to the indicator
are made at connector J5 on the ProÞbus board (see
Figure 2-2 on page 2 for board location of J5).
Figure 2-4 shows the J5 connector layout for the
ProÞbus Indicator Interface. Table 2-1 shows the
serial communications connections between the
ProÞbus Indicator Interface and the IQ plus 800/810
indicators; Table 2-2 shows the serial communications
connections between the ProÞbus Indicator Interface
and the IQ plus 310A indicators.
Figure 2-4. Serial Communications Connections
Table 2-1. IQ plus 800/810 Indicator-to-ProÞbus Serial
Port Pin Assignments
NOTE:
The 20 mA current loop interface connection
requires that the 20 mA option be installed in both the
ProÞbus Indicator Interface and the IQ plus 800/810.
See Section 2.1.5 for information about installing the
20 mA option.
Table 2-2. IQ plus 310A Indicator-to-ProÞbus Serial Port

the network bus, install jumpers JMP3 and JMP4 on
the ProÞbus board (see Figure 2-2 on page 2 for
jumper locations).
2.1.5 Installing the 20 mA Current Loop Option
The ProÞbus Indicator Interface can communicate
with IQ plus 800/810 indicators using the 20 mA
current loop interface if the option is installed in both
the Interface and the indicator. Installing the 20 mA
option disables RS-232 communications.

Profibus Address
Switches SW1-1 through SW1-8 are used to set the
address of the ProÞbus Indicator Interface. Use
Table 2-4 to select the correct switch settings for the
network address. Note that setting a switch OFF acts
as a logical Ò0Ó and that SW1-1 represents the least
signiÞcant bit (LSB) of the network address.
The conÞgured address equals the sum of the values
of the switches set on. For example, to set a network
address of 19, SW1 switches would be set as shown in
Table 2-5:
For hexadecimal addressing, SW1 functions as shown in Table 2-6. Repeating the example from Table 2-4,
decimal 19 is hexadecimal 13: Switch 1-5 (1 in byte 1) and switches 1-2 and 1-1 (2+1 = 3 in byte 0) would be set
on for an address of hex 13.
Indicator Type
Switches SW2-1 and SW2-2 set the type of indicator
attached to the ProÞbus Indicator Interface.
Indicator Data Rate
Switches SW2-3 and SW2-4 set the data rate used for
communications between the indicator and the
ProÞbus Indicator Interface. Set to 9600 bps for the IQ
plus 310A.
Stop Bits
Switch SW2-5 sets the number of stop bits used to
communicate with the indicator. Set SW2-5 OFF for
one stop bit, ON for two stop bits.
Parity
Switches SW2-6 and SW2-7 set the type of parity
used to communicate with the indicator.

3.4 Command Examples
This section provides examples of 20-bit integer and 32-bit ßoating point commands used to send and receive
indicator data.
3.4.1 Retrieve Net Weight Data (20-bit)
Table 3-9 shows a binary representation of the 20-bit output data used to retrieve net weight from the indicator
using command 28. The output format includes only the command number, in byte 0 of word 0 (0001 1100 =
hex 1C, decimal 28).
Table 3-10 shows the input data returned by the previous command:
¥ The status bits in word 1 (see Section 3.3 on page 12) show that a tare has been performed and the
indicator is in net mode.
¥ Weight data is returned in word 3 (0000 0111 1101 0101 = hex 07D5 = decimal 2005). Assuming the
indicator is conÞgured to display pounds, with one decimal position, the net weight is interpreted as
200.5 LB.
3.4.2 Retrieve Net Weight Data (32-bit)
Table 3-11 shows a binary representation of the 32-bit output data used to retrieve net weight from channel 2 of
an IQ plus 800/810using command 261. The output format includes the command number, in byte 0 of word 0
(0001 0001 1100 = hex 105, decimal 261), the channel number (0100, decimal 2) in the lower byte of word 1.

Table 3-12 shows the input data returned by the previous command:
¥ The command number for which the data is returned is included in word 0 (command 261).
¥ The status bits in word 1 (see Section 3.3 on page 12) show that a tare has been performed and the
indicator is in net mode.
¥ Weight data returned in words 2 and 3 must be copied into a ßoating point storage location before being
read.
3.4.3 Send Setpoint Value (32-bit)
Table 3-13 shows a decimal representation of the
32-bit output data used to set the value of setpoint 1 to
100.5. Note that the setpoint value is not readable as
100.5: The value data must be copied to words 2 and 3
from a ßoating point storage location.
After sending the command, use the Read Setpoint
Value command (decimal 266) to verify that the
indicator received the correct setpoint value.
3.4.4 Read Setpoint Value (32-bit)
Table 3-14 shows the output data used to read the
value of setpoint 1.
Table 3-15 shows the data returned by the previous
command. Again, the value data returned in words 2
and 3 must be copied into a ßoating point storage
location to be read.

4.1 Troubleshooting
The following section provides information for diagnosing communications problems between the indicator and
the ProÞbus master. The status of the LEDs on the ProÞbus Indicator Interface can be used to diagnose the
general area of difÞculty, as shown in Table 4-1.
If there is no communication between the indicator and the master device, do the following:
1. Ensure DIP switches on the ProÞbus board are set correctly (see Section 2.2 on page 4).
2. Power down,then power up the ProÞbus Indicator Interface.
3. Ensure the ProÞbus master device is set to send a command to the slave. Commands are listed in
Section 3.0 on page 8.
4. Check the OUTPUT and RxD jumpers to ensure they are set for RS-232 communications (see
Section 2.1.1 on page 3).
5. Check the wiring from the indicator to connector J5 on the ProÞbus board (see Section 2.1.2 on page 3).
6. Ensure the indicator conÞguration is correct.
7. Check that the master is set up correctly to communicate with the slave device.
8. On the ProÞbus board, ensure that the 3.3V LED is lit. If it is not, check connector J6 for a loose or
incorrect connection (see Figure 2-2 on page 2). If the LED is still not lit, replace the ProÞbus Indicator
Interface power supply.
9. Locate EPROM U7 found in the middle of the ProÞbus board (see Figure 2-2 on page 2). Ensure that the
chip is seated by pressing down on the chip.
10. Check that the connector J4 on the ProÞbus board is Þrmly connected.
11. If no problems are found in the checks above, replace the ProÞbus board.
Symptom Possible Cause
POWER LED not lit No power to Profibus board. Ensure connector J6 on the Profibus
board is properly seated.
RxD LED flashes constantly; TxD LED not lit Indicator is streaming data to the Profibus slave. Check indicator
configuration. See Section 2.4 on page 7 for indicator configuration
information.
TxD LED flashes every two seconds; RxD LED not lit Serial connection between the indicator and the Profibus Indicator
Interface is not correct. See Section 2.4 on page 7 for indicator
configuration information.
