6. PROGRAMMING IN A SYSTEM WITH CHANNELS. Spindle swapping. CNC 8065 (REF: 1103) ·106· 6.4.6 Variables related to the spindle configuration of the channel. (V.)[ch].G.NSPDL Variable that can only be read from the program, PLC and interface. The variable returns the value of block preparation. Report variable (to be used from the scripts). Number of spindles of the channel. Syntax. ·ch· Channel number. V.[2].G.NSPDL Channel ·2·. (V.)[ch].G.MASTERSP Variable that can only be read from the program, PLC and interface. The variable returns the value of block preparation. Logic number of the master spindle of the channel. Syntax. ·ch· Channel number. V.[2].G.MASTERSP Channel ·2·. Execution channels (V.)[ch].A.ACTCH.xn (V.)[ch].A.ACTCH.sn (V.)[ch].SP.ACTCH.sn Variable that can only be read from the program, PLC and interface. Variable valid for rotary and linear axes as well as for spindles. The variable returns the value of execution or preparation depending on the axis or spindle. Current channel of the axis or of the spindle. Syntax. ·ch· Channel number. ·xn· Name, logic number or index of the axis. ·sn· Name, logic number or index of the spindle. V.A.ACTCH.Z Z axis. V.A.ACTCH.S Spindle S. V.SP.ACTCH.S Spindle S. V.SP.ACTCH Master spindle. V.A.ACTCH.4 Axis or spindle with logic number ·4·. V.[2].A.ACTCH.1 Axis with index ·1· in the channel ·2·. V.SP.ACTCH.2 Spindle with index ·2· in the system. V.[2].SP.ACTCH.1 Spindle with index ·1· in the channel ·2·. Remarks. The variable returns the value of execution or preparation as follows. If the spindle belongs to the channel requesting the variable, it returns the preparation value; if the axis or spindle belongs to a different channel, the variable returns the execution value and interrupts block preparation. Special returned values. This variable returns one of the following values. Value. Meaning. 0 The axis or spindle is not in any channel. 1 - 4 Channel number.
Execution channels 6.5 Communication and synchronization. Each channel may execute its own part-program independently and in parallel with the rest of the channels, but it can also communicate with them to share information or synchronize at particular points. The communication between channels takes place on the basis of a number of marks managed by the part-programs of each channel. These marks establish whether the channel is waiting to be synchronized or it may be synchronized, etc. There are two different ways to synchronize, each offers a different solution. The synchronization marks of both methods are independent from each other; the marks of each method neither affect nor are affected by the marks of the other one. Synchronization of channels interrupting the execution of all the channels involved. Synchronization of channels interrupting the execution of all the channels involved. #MEET instruction. The #MEET instruction provides the easiest way to synchronize. This instruction activates a mark in its own channel and sets the channel waiting until the same mark is active in the indicated channels. This method interrupts the execution in all the channels involved in the synchronization. The set of marks being used are initialized after executing an M02 or an M30, after a reset or on power-up. Synchronization of channels without interrupting the execution of all the channels involved. Instructions #SIGNAL - #WAIT - #CLEAR. The instructions #SIGNAL, #WAIT and #CLEAR are a method somewhat more complicated than the previous one, but more versatile. This instruction #SIGNAL activates the marks in its own channel and #WAIT sets the channel waiting until the indicated mark is active in the indicated channel. This method does not interrupt the execution in all the channels in order to synchronize. The set of marks being used are maintained after executing an M02 or an M30, after a reset or on power-up. Other ways to synchronize channels. Synchronization of channels without interrupting the execution of all the channels involved. #MEET #SIGNAL - #WAIT - #CLEAR The CNC interrupts the execution in all the channels in order to synchronize. The marks are initialized after executing an M02 or an M30, after a reset or on power-up. The CNC does not interrupt the execution in all the channels in order to synchronize. The marks are not initialized after executing an M02 or an M30, after a reset or on power-up. The common arithmetic parameters can also be used to communicate and synchronize channels. By writing a certain value from a channel and later reading it from another channel, it is possible to set the condition to follow up on the execution of a program. Accessing the variables of a channel from another channel can also be used as a way to communicate. Swapping axes between channels also makes it possible to synchronize processes, because a channel cannot grab an axis until it has been released by another one. 6.
