M800V/M80V Series PLC Interface Manual
4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
[Related signals]
(1) T code data 1 to 4 (R536 to 43)
(2) M function finish 1 (FIN1: YC1E)
(3) M function finish 2 (FIN2: YC1F)
(4) Miscellaneous Function Command High-speed Output: T function finish 1 to 4 (TFIN1 to 4: YD30 to 3)
Cont. Signal name
A 2nd M function strobe 1 to 4
[Function]
This signal informs that the 1st set of 2nd M function is selected by the machining program in automatic operation
(memory, MDI or tape) or by manual numerical command.
The 2nd M function is also called the B function.
With the signal (BF1), user PLC receives 2nd M function data 1 to 4.
[Operation]
<Normal method (when the parameter "#1278 ext14/bit1" is set to "0")>
This signal turns ON when:
 The 2nd M function (B code) is specified in automatic operation (memory, MDI or tape).
 2nd M function (B code) is issued by manual numerical command input.
This signal turns OFF when:
 The "M function finish 1" signal (FIN1) or the "M function finish 2" signal (FIN2) is turned ON.
 Reset condition occurs. (Refer to the section on "In automatic operation "run"" signal (OP) for details on the reset condi-
tions.)
Note
(1) Four 2nd M functions can be issued in one block at a time.
The relationship between machining program and 2nd M function strobe is shown below.
Machining program
(2) The "2nd M function strobe 1 to 4" (BF1 to 4) is not output during operation with M function lock (AFL signal ON).
(3) In the case of manual numerical command input, outputs are in accordance with the "2nd M function strobe 1" (BF1).
(4) Address for 2nd M function can be selected from addresses A, B and C by using machine parameter. Set so that the
address is different from the axis address.
<High-speed method (when the parameter "#1278 ext14/bit1" is set to "1")>
Refer to the section on "Miscellaneous Function Command High-speed Output: 2nd M function finish 1 to 4" (BFIN1 to 4).
[Related signals]
(1) M function finish 1 (FIN1: YC1E)
(2) M function finish 2 (FIN2: YC1F)
(3) Miscellaneous Function Command High-speed Output: 2nd M function finish 1 to 4 (BFIN1 to 4: YD34 to 7)
