PLC Module 9036—Write status information, activate/deactivate functions

The virtual tool axis VT can be selected under number 6 using the value 999

The active handwheel can be defined with the new selection parameters 20

(active handwheel) and 21 (standard handwheel) if more than one

handwheel is connected to the control. Number 70 (active handwheel) and

number 71 (standard handwheel) of the PLC Module 9035 can be used to

read back the currently active handwheel.

Note on PLC Module 9193 – Set the operating times

So as not to impair the behavior of the overall system, the module may only

be used for re-initializing the machine times, and may not be called too

often. The behavior of the module was changed such that the module (and

therefore the calling submit or spawn job) waits for acknowledgment.

Note on PLC Module 9132 – Selection of override potentiometers

If PLC Module 9132 was used to select another machine operating panel,

no automatic reset to the operating panel with the number 0 took place

when the PLC was restarted (e.g. compile, acknowledgment of PLC run-

time error).

Note on PLC Module 9228, 9229 – Coupling function for auxiliary axes

As long as the coupling function in the interpolator has not taken effect,

status module 9229 reports the status "0" for the coupling axis (0: No

coupling function active for programmed axes).

Until now, PLC Module 9229 reported an active coupling function as soon

as the coupling function was requested via PLC Module 9228, even if the

coupling function had not yet taken effect in the interpolator.
