6.1

WHAT IS PMC?

The programmable machine controller (PMC) is a programmable controller (PC) built into a CNC to

perform sequence control for a machine tool (spindle rotation, tool change, machine operator's panel

control, and so on).

Sequence control is to perform control steps successively in a predetermined sequence or according to the

logic operation.

Programs for performing sequence control for machine tools are called sequence programs. Generally,

sequence programs coded in the Ladder language are used.

6.1.1

Basic Configuration of PMC

The following is the basic configuration of the PMC:

Fig. 6.1.1 Basic configuration of PMC

The sequence program reads input signals, performs operations, and outputs results in a predetermined

sequence.

6.1.2

I/O Signals of PMC

Input signals of the PMC include signals input from the CNC (such as M and T function signals) and

signals input from the machine (such as the cycle start button and feed hold signal button). Output

signals of the PMC include signals output to the CNC (such as the cycle start command and feed hold

signal command) and signals output to the machine (such as turret rotation and spindle stop). The PMC

controls these I/O signals by executing a sequence program to control the machine tool.

6.1.3

PMC Signal Addresses

PMC signal addresses indicate the locations of I/O signals exchanged with the machine, I/O signals

exchanged with the CNC, and signals for internal relays and data (PMC parameters) in nonvolatile

memory. PMC addresses are roughly classified as shown in Fig. 6.1.3 (a).

Fig. 6.1.3 (a) PMC-related addresses

The PMC signal address format consists of an address number and bit number (0 to 7) as follows:

Bit number (0 to 7)

Address number (letter followed by decimal

number)

Fig. 6.1.3 (b) PMC address format

The first letter of an address number represents the type of the signal.

In sequence programs, an address of a byte may be specified. In the above example, specify X127

to specify a byte address. In this case, the period "." and bit number are unnecessary.

Table 6.1.3 lists the address symbols and corresponding signals.

System Relay Addresses (R9000)

The System Relay is used to control a sequence program by PMC System software. And, some addresses

such as 'Operation results of functional instructions' are used to condition of a sequence program.

Table 6.1.4 (a) Address of System Relay

Operation results of functional instructions

This area holds information necessary for individual ladder levels, such as the operation results of

functional instructions. This information is saved/restored when the task is switched.

3 Each pulse signal (ON-OFF signal) has an error of ±8 msec (ladder execution

period).

Ladder execution start signal

Ladder stop signal

Ladder execution status signal

Using the ladder execution start and stop signals in a ladder program can detect when the ladder program

starts and stops.

Referencing the ladder execution status signal from an external system or program, such as the network

board, C Language executor program, FOCAS2 Ethernet, or HSSB library, can detect the execution status

of the ladder program.

Ladder execution start signal (R9015.0)

When directed to start ladder program execution, the system software starts executing the ladder

program, turns on this signal, and keeps it on for the first one scan cycle. Like R9000, this signal

indicates the status of ladder execution corresponding to each ladder execution level. For this

reason, this signal is securely turned on for the first one scan cycle after the start of execution no

matter on what execution level the signal is referenced. This signal is turned on when:

(a) Ladder execution begins at power turn-on.

(b) The [RUN] soft key on the PMC screen is pressed.

(c) FANUC LADDER-III or a ladder editing package directs the ladder to start.

Referencing this signal in a ladder program can detect when ladder execution has begun, making it

possible to program preprocessing related to ladder execution.

CAUTION

Reference this signal only within a ladder program. Do not reference it from an

external system or program as it indicates the status of ladder execution

separately for each ladder execution level.

(2)

Ladder stop signal (R9015.1)

When directed to stop ladder program execution, the system software turns off this signal and keeps

it off for the last one scan before stopping ladder program execution. Like R9000, this signal

indicates the status of ladder execution corresponding to each ladder execution level. For this

reason, this signal is securely turned off for the last one scan before the stop of execution no matter

on what execution level the signal is referenced. This signal is turned off when:

(a) The [STOP] soft key on the PMC screen is pressed.

(b) FANUC LADDER-III or a ladder editing package directs the ladder to stop.

(c) On the PMC DATA I/O screen, the ladder program is loaded to the PMC.

(d) FANUC LADDER-III or a ladder editing package stores the ladder program to the PMC.

Referencing this signal in a ladder program can detect when ladder execution stops, making it

possible to program post processing related to ladder execution (that is, preprocessing for ladder

execution stop). Before the ladder is stopped, for example, it is possible to put signals in a proper

state for safety purposes.

CAUTION

1 Reference this signal only within the ladder program. Do not reference it from

an external system or program as it indicates the status of ladder execution

separately for each ladder execution level.

2 If the power is turned off or a CNC system alarm occurs, ladder execution and

I/O signal transfer are immediately stopped for safety purposes. In this case,

therefore, this signal cannot be used.

(3) Ladder execution status signal (R9091.2)

Referencing this signal from an external system or program, such as the network board, C language

executor program, FOCAS2 Ethernet, or HSSB library, can detect the execution status of the ladder

program.

(4) Example of using the signals

NOTE

1

A program can be created on level 3 for the compatibility with programs for other

models, but it is not executed.

2

The maximum overall program size (including the maximum number of ladder

steps, symbols/ comments, and messages) varies depending on option settings.

See PMC PROGRAMMING MANUAL (B-64393EN) .

3

For the number of functional instructions, each parenthesized number indicates

the number of all functional instructions, and each non-parenthesized number,

the number of valid functional instructions.

4

To use the Function Block function, its option is necessary for each CNC. When

specifying this option, the Extended PMC Ladder Instruction Function can also

be used. Because the Extended PMC Ladder Instruction Function is included in

the Function Block function, it is not necessary to order the option of the

Extended PMC Ladder Instruction Function separately.

5

These are the number for extended symbol and comment character. The

number of basic symbol character is 16 and the number of comment character is

30. Refer to PMC PROGRAMMING MANUAL (B-64393EN) for details

6

This number is the number of single-byte characters. When you use double-byte

characters as a comment, the number becomes half.

7

The capacity of the program storage area varies depending on option settings.

See PMC PROGRAMMING MANUAL (B-64393EN).

8

Maximum input/output number of I/O link for 0i Mate-D is 256points/256points.
