6-5-7 Word n+1 Bit 07: Program Number Read Bit (Task 1)
This bit specifies the number of the MC program that will be executed; it is valid
only when the mode is set to automatic mode. The status of this bit is referenced
when the Cycle Start Bit goes ON. If this bit is ON when the Cycle Start Bit goes
ON, the program number set in word n will be read and the specified program will
be executed from the beginning.
When any MC programs in the same task have been edited, added, or deleted,
always make sure that this bit is ON the next time that the Cycle Start Bit is turned
ON. An error will occur if the Program Number Read Bit is OFF.
Signal The Program Number Read Bit settings have the following functions.
Signal Function
ON Indicates to read the program number from word n.
Note Refer to the Cycle Start Bit (n+1 bit 02).
6-5-8 Word n+1 Bit 08: Teaching Address Set Bit (Task 1)
This bit specifies the leading address of the position data addresses containing
the current position for teaching. The Teaching Address Set Bits for task 2 (bit 08
in word n+3) operate in the same way.
At the rising edge of this bit, the teaching start address set in the expansion data
area will be set as the first address for teaching.
This bit is available when the expansion data area is valid. Immediately after
power is turned ON the teaching address is 0.
This bit is effective when it goes from OFF to ON (up-differentiation), but keep
the bit ON until the Teaching Address Setting Completed Flag goes ON.
Signal The Teaching Address Set Bit settings have the following functions.
Signal Function
↑ (OFF-to-ON) The teaching start address set in the expansion data area is
transferred to the MC Unit and set as a teaching execution
address.
