2.0 Setup
Each SCT scale module comes with two parallel RS-485 ports with RJ45 connectors. The ports are used to connect the SCT
scale modules with the corresponding port on the fieldbus module. SCT scale modules can be connected in line (up to 16
weighing scales) by connecting each SCT scale module to the next one and the first SCT scale module to the fieldbus module.
This creates a network that can be managed by one or more PCs.

The folowing table lists out required PC setup connections to a PC:

2.1.3 SCT-2200 Fieldbus Hub Mode Configuration Settings
1. Navigate to FLDBUS.
• For firmware version 7.15 or earlier, see Section 2.1.1 on page 3
• For firmware version 8.04, see Section 2.1.2 on page 4
2. Select the type of fieldbus:
•ProFib - Profibus
•Eth.IP - Ethernet IP
•Profin - PROFINET
•Eth.Cat - EtherCAT
•Canopn - CANopen
•Dev.net - DeviceNET
•Mb.tcp - Modbus TCP/IP
3. Once the type of fieldbus is selected, enter the appropriate parameters (see Figure 2-4):
• Profibus
node.id: sets the Profibus ID of the module
• Ethernet IP, PROFINET, Modbus TCP/IP:
Aut.cfg: auto IP configuration (no/yes)
IP.Add: sets the IP address
Net.msk: sets the net mask address
Gat.way: sets the default gateway
Set baud rate to 115200 for best performance
• CANopen:
Nod.add (1-127): sets the node address of the module
Baud.r: baud-rate, value: 1 MB, 800 kB, 500 kB, 250 kB, 125 kB, 100 kB, 50 kB, 20 kB, 10 kB
• DeviceNET:
Mac.id (0-63): sets the MAC ID of the module
Baud.r: baud-rate, value: 500kB, 250kB, 125kB
4. Set the number of SCT scale modules (NUM.SCA) for the 485 sub-network managed by the primary hub device (1 to
16).
5. Set SCA.ADD in secondary devices(visible if NUM.SCA is greater than 1): 485 address of the scale, if NUM.SCA is equal
to 1 the 485 address is set equal to 1. See Section 2.7 on page 15 for hub mode parameters.

2.2 Input and Output Data Areas
There are two data areas. An input area is read by the fieldbus module and the output area is written from the fieldbus module.
All the numeric values have the big-endian format (the first byte is the most significant one).
2.2.1 Input Data Area
The input data area is read by the Fieldbus module and is made up of 16 registers, each of 2 bytes (32 bytes overall total).
GROSS WEIGHT and NET WEIGHT value format (0-3 registers) whole numbers value (no decimals).
Example:
if 3 decimals are set, the 3,000 value is read 3000
if 2 decimals are set, the 3,00 value is read 300
2.2.2 Input Register Status
Input register number 4 with two bytes is defined in Table 2-4.
