Project description

https://img.shields.io/travis/pcdshub/ads-async.svg https://img.shields.io/pypi/v/ads-async.svg

Asyncio (or sans-i/o) TwinCAT AMS/ADS testing server in pure Python.

… and maybe a prototype client, too.

Requirements

  • Python 3.6+

  • (Optional) pytmc (for loading .tmc files in the server)

Server Functionality

  • Reference asyncio implementation.

  • Loads .tmc files for symbol information (basic types only).

  • Supports read, write, read/write of symbols (by handle or name).

  • Supports ‘sum up’ bulk reads (by way of read_write).

  • Pretends to create/delete notifications (not yet working)

Client Functionality

  • Preliminary symbol, handle, and notification support

  • LOGGER port message decoding

  • Shortcuts for common information (project/application/task names, task count)

  • Ability to easily prune unknown notification handles

  • Automatic reconnection

  • Log system configuration
