Tightening machine as a PLC device
From PlcWiki
The most important properties of a tightening machine defined as a PLC device are its name and channelnumber. These two entries uniquely identify a tightening machine or its spidle.
channelnumber is a logical ID of single tightening spindle connected to a PLC client. It can be any non-zero positive integer as it's only purpose is to assign the tightening tool to appropriate operation. It has no other meaning.
Be aware to use channelnumber setting, not channel. channel is a deprecated setting with many side effects and should not be used anymore.
When a tightening machine has more than one spindle, this setting applies to the first of them. Other spindles' channelnumbers are assigned in sequential order. E.g. if this option is set to 3 and the machine has 2 spindles, then the first spindle has the channelnumber 3 and the second one has the channelnumber 4. The next usable channenumber value is 5.
.settings.channelnumber should match operation's .ChannelNumber value and the device name (i.e. tmachine_1) should match operation's .Device value.

Generally we send these messages to controllers however it also depends on the configuration:
| MID 1 (rev 3) | Communication start |
| MID 60 (rev 2) | Last tightening result data subscribe |
| MID 14 | Parameter set selected subscribe |
| MID 17 |
Parameter set selected unsubscribe |
| MID 34 | Job info subscribe |
| MID 37 |
Job info unsubscribe |
| MID 70 |
Alarm subscribe |
| MID 18 | Select Parameter set |
| MID 38 |
Select job |
| MID 127 |
Abort job |
| MID 16 | Parameter set selected acknowledge |
| MID 43 | Enable tool |
| MID 42 | Disable tool |
| MID 9999 | Keep alive message |
| MID 62 | Last tightening result data acknowledge |
| MID 50 |
Vehicle ID Number download request |
| MID 19 |
Set Parameter set batch size |
| MID 224 |
Set digital input function |
We accept any MID from the controller, the most important MIDs for us are these:
| MID 5 | Command accepted |
| MID 61 | Last tightening result data |
| MID 15 | Parameter set selected |
| MID 35 | Job info |
The communication starts like this:
| PC | direction | controller | meaning |
| MID 1 | -> | Communication start |
|
| <- | MID 2 | Communication start acknowledge |
|
| MID 60 | -> | Last tightening result data subscribe | |
| <- | MID 5 | Command accepted | |
| MID 14 | -> | Parameter set selected subscribe | |
| <- | MID 5 | Command accepted | |
| MID 34 | -> | Job info subscribe | |
| <- | MID 5 | Command accepted | |
| MID 70 | -> | Alarm subscribe | |
| <- | MID 5 | Command accepted |
That's the initial handshake.
Then communication is driven by the needs of the client.
A typical conversation using parameter sets looks like this:
| PC | direction | controller | meaning |
| MID 42 |
-> | Disable tool |
|
| <- | MID 5 |
Command accepted |
|
| MID 18 |
-> | Select Parameter set | |
| <- | MID 5 | Command accepted | |
| <- | MID 15 | Parameter set selected | |
| MID 43 |
-> |
Enable tool |
|
| <- |
MID 5 |
Command accepted | |
| <- |
MID 61 |

MID 61 | Last tightening result data | |
| <- |
MID 61 | Last tightening result data | |
| MID 42 |

A typical conversation using jobs looks like this:
| PC | direction | controller | meaning |
| MID 42 |
-> | Disable tool |
|
| <- | MID 5 |
Command accepted |
|
| MID 127 |
-> | Abort job |

We need to send "Abort job" before selecting one to make sure there is no job in progress.
Also the unsubscribe/subscribe trick is used to force sending "Job info" even if the job isn't changed, we need this message as a confirmation of successful job selection and as a flag we are good to enable the tool (Only Stanley controllers need this trick, AtlasCopco sends "Job info" in all cases after "Select job").
