Setup

This guide covers the transmit-capable IOU13 (Bitbus Slave Variant) running the bbslave firmware. The Bitbus demo uses internal loopback to exchange messages between a simulated master and the slave on one module.

Prerequisites

Hardware

  • A Moducop Edge Computer with a IOU13 (Bitbus Slave Variant) installed
  • A development PC (Windows or Linux), connected via Network to the Moducop

No Bitbus cable, external master, or second Bitbus device is required.

Tools on Development PC

The examples are written in programming language Go, we download the go sources and compile them. Therefore we need some tools on your development PC:

Get Demo Software

Clone the repository containing the examples to a folder of your choise (here myworkdir).

c:
cd \myworkdir
git clone https://github.com/ci4rail/io4edge-client-go.git
cd io4edge-client-go

cd ~/myworkdir
git clone https://github.com/ci4rail/io4edge-client-go.git
cd io4edge-client-go

Determine the Service Address of your IOU13 (Bitbus Slave Variant)

Io4Edge Devices are usually addressed by their service address, which is a name in the network.

The IOU13 (Bitbus Slave Variant)'s service name depends on the ModuCop's slot and is usually S101-IOU13 (Bitbus Slave Variant)-USB-EXT-<slot-number>[-<function>], i.e. if the IOU13 (Bitbus Slave Variant) is in the slot next to ModuCops CPU01, we have the following service names:

Service Name Description
S101-IOU13-USB-EXT-1 Core function
S101-IOU13-USB-EXT-1-com Serial interface
S101-IOU13-USB-EXT-1-bitbus Bitbus sniffer and sender
S101-IOU13-USB-EXT-1-bbslave Bitbus slave

We need this service address in the demo programs to address the module.

If you are unsure, you can also browse the available devices: 

ssh root@<moducop-ip>

Once logged in into the Moducop Shell: 

io4edge-cli scan -f

If your IOU13 (Bitbus Slave Variant) is in the slot next to the CPU, the output should be: 

DEVICE ID                   SERVICE TYPE                    SERVICE NAME                 IP:PORT
S101-IOU13-USB-EXT-1        _io4edge-core._tcp              S101-IOU13-USB-EXT-1         192.168.201.1:9999
                            _ttynvt._tcp                     S101-IOU13-USB-EXT-1-com   192.168.201.1:10000
                            _io4edge_bitbusSniffer._tcp     S101-IOU13-USB-EXT-1-bitbus   192.168.201.1:10001
                            _io4edge_bitbusSlave._tcp       S101-IOU13-USB-EXT-1-bbslave   192.168.201.1:10002
