Example of a program in which output of m code to the outside is used
The program below shows an example of control in which auxiliary unit control commands are
transferred to the PLC by I/O signals while using the FX
2N
-20GM and a general PLC. In this
program, the FX
0N
-60MR is used as the general PLC.
(While the positioning unit is connected to the FX
2N
/
2NC
Series PLC, m codes can be trans-
ferred via communication with the buffer memory.)
Description of operations
1) When a program including the m code is executed in the FX
2N-
20GM, the m code output
(Y10 to Y17) as 2-digit BCD and the m code ON signal (Y07) are turned ON.
2) The programmable controller coverts them into binary and decodes them, then drives the
specified auxiliary equipment control output in accordance with the decoded output.
3) In this example, when the m code "m** (** = 00 to 99)" is executed in the FX
2N
-20GM, the
auxiliary relay M** (** = 00 to 99 equivalent to the m code) in the programmable controller is
turned ON.
4) The programmable controller confirms the operation of the auxiliary equipment, then drives
the m code OFF command output (Y00).
5) When receiving the m code OFF command input (X07), the FX
2N
-20GM turns OFF the m
code ON signal (Y07) and processes the next instruction.
Set the parameters as follows.
PARA. 36: "1"External output of the m code is valid.
PARA. 37: "7"The head No. of the destination for m code output is set to "Y07".
PARA. 38: "7"The m code OFF command input No. is set to "X07".
