Communication between manager and PLC.
7.3.1 Manager --> PLC communication.
The manager uses the following registers and marks to inform the PLC about the operations
it must carry out. Some signals are per channel whereas others are per magazine. The
following table shows the mnemonics for each mark (M) or register (R) in each channel or
magazine.
TMOPSTROBE
The channel tool manager sets this mark high (=1) to let the PLC know that it must execute
the operation indicated by the TMOPERATION mark of the channel.
LEAVEPOS
This register indicates the magazine position to leave the tool. While selecting a turret
position (#ROTATEMZ instruction), this register takes the value of ·0· if it is a positive relative
positioning and the value of ·1· if it is a negative relative positioning.
TAKEPOS
This register indicates the magazine position of the tool to be taken. While selecting a turret
position (#ROTATEMZ instruction), this register takes the value of ·0· if it is an absolute
positioning and the value of ·1· if it is a relative positioning.
NEXTPOS
This register indicates the magazine position occupied by the next tool. While selecting a
turret position (#ROTATEMZ instruction); in an absolute positioning, this register indicates
the position to reach and, in a relative positioning, the number of positions to rotate.
MZID
This register indicates which magazine contains the tool requested by the channel.
When two magazines are involved in a tool change, the lower portion of this register indicates
the destination magazine for the tool and the higher portion the source magazine for the tool.
