S7 Micro Service - device service for connecting Siemens S7(S7-200, S7-300, S7-400, S7-1200, S7-1500) devices by ISO-on-TCP to EdgeX.

• This device service is contributed by YIQISOFT
• The sevice has tested on S7-300, S7-400, S7-1200

• Single Read and Write
• Multiple Read and Write
• High performance, more 2000 items per second(depends on S7 model)
  • Use S7-Device01 sample device configuration, interval should be less than IdelTimeout
  • S7-1200 and S7-1500 preferred
  • Create multiple connections to one S7 device use different device name

• A Siemens S7 series device with network interface
• Enable ISO-on-TCP connection on the S7 device

1. Clone the device-rest-go repo with the following command:

   git clone https://github.com/edgexfoundry/device-s7.git
   

2. Build a docker image by using the following command:

   make docker
   

3. Alternatively the device service can be built natively:

   make build
   

Currently, the NATS Messaging capability (NATS MessageBus) is opt-in at build time. This means that the published Docker images do not include the NATS messaging capability.

The following make commands will build the local binary or local Docker image with NATS messaging capability included.

make build-nats
make docker-nats

This component is packaged as docker images.

Please refer to the Dockerfile and Docker Compose Builder scripts.
