Tightening machine as a PLC device

From PlcWiki

Revision as of 09:26, 25 January 2011

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.

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.
