Workflow
1. PLUS sends PN or KN and a TMU to the TC.
2. The TC converts the TMU to a mode number and makes the tightening.
3. When the tightening is finished the cycle data is sent to PLUS.
PLC program
Normal workflow:
1. PLUS sends a PN or KN and a TMU to the TC. The PN or KN is automatically copied to
CURRIDSTRING with a “PN” or “KN” added as prefix. The TMU is automatically converted to a
mode number and the result is placed in PLUS_MODE.
2. PLUS_MODE is copied to MODE by the PowerMACS PLC. This mode is started and
CURRIDSTRING will be included as Wp. Id in the cycle data.
NSCR:
If PLUS sends the telegram NSCR it means that no tightening shall be made for the PN or KN and
TMU that was just received. This is indicated to the PLC by clearing the CURRIDSTRING and
PLUS_MODE. If this happens the PLC program must recognize this and not start a tightening.
Automatic and Manual mode:
The VBA station can operate in Automatic or Manual mode. Automatic mode is the normal case and is
the one that is describe in the picture above. In manual mode no connection to PLUS is needed, the
PLC receives the mode number from some other device and no cycle data shall be sent to PLUS. The
PowerMACS PLC must inform the TC that the station is running in manual mode with the PLC variable
PLUS_MANUALMODE to make sure no data is sent.
