Control Operate the PLC - part 4

4.2.3.7. Programming Console

This programming tool is a tool used to insert, edit, modify and monitor existing programs in the PLC memory in the form of mnemonic codes. Programming Console can be set to PROGRAM, MONITOR or RUN.


PROGRAM: to make or modify or improve the program.

MONITOR: to change the value of the counter and timer settings when the PLC still operate

RUN: to operate the PLC without being able to change the value of the existing settings.

a. Function keys on the Programming Console


To call the desired FUNction, after pressing this button, followed by two digits / number that corresponds to the desired function number




Displaying ShiFT register operations




Used together with LD, AND, or OR to indicate the NC contacts (normally closed), used with OUT to indicate the inverse output and is also used to define the active functions for a moment when it is used together with FUN


DAN, to enter the inputs in series with the previous input




OR, to enter the inputs in parallel with the previous input




CouNTer is controlled with this command, both for functionality as well as to contact the output of this function



LoaD, to enter the desired input as the initial part of the ladder




OUTput of circuit




TIMer controlled with this command, either to function or to contact of the output of this function



Defining Temporary Relay




Defining Link Relay




Defining Holding Relay




Defining Auxiliary Relay




Defining Data Memory




Defining an indirect DM address





Defines the word address




Defines operand as Constant




Defines the address bits




SHIFT is used as a substitute for the function of four buttons with better usability, written PLAY, RECORD, Channel and Contact


Enter the decimal and hexadecimal form when programming





b. Operate the Programming Console

Incorporate Password (mode R, M, P)

To enter a password, press:



Figure 4.59. Procedures to enter the password




• Buzzer ON / OFF (mode R, F, P)

To turn on or turn off the buzzer, press:



Figure 4.60. Procedure enable the Buzzer



Removing the program ( mode P )

To clean all memory that can be removed in the Program Memory and IR, HR, AR, DM, and TC, press:



Figure 4.61. Procedure to uninstall the program




• Insert the program (mode P)

Set the mode selector switch with a key to the PROGRAM position, Press CLEAR if necessary until 0000 to appear on the screen. Furthermore, do procedures to insert the program such as the following example.

Figure 4.62. Procedure to insert the program




• Reading the program (mode R, M, P)

For reading the program, press:


Figure 4.63. Procedures to read the program




• Removing / inserting a program ( mode P )

To remove or insert a program, press:



Figure 4.64. Procedure delete / insert a program



• Search for part of the program (mode R, M, P)

To search for contacts, timers, counters, instruction or address that the program has made, press:



example;
Figure 4.65. Procedures to search the program



• Clear the error message (mode P)

To remove the error message, press:


Figure 4.66. Procedure to remove the error message



• Check the program ( mode P )

Programs that have been input must be checked. Checking the program can be used to find the three levels of writing errors in the program.

Figure 4.67. Procedure to check the program






• Monitor the program (mode R, M, P)

To monitor the desired program, press:


Figure 4.68. Procedures to monitor the program




• Change the setting value of timer and counter ( mode M,P)

To change the setting value of timer and counter are two ways to enter new values or by subtracting / adding one of the existing value.


Figure 4.69. Procedure to change the value of the timer and counter




• Displaying the Cycle time / cycle time of execution (mode M,R)

After the program was checked and no error then cycle time of the program execution can be displayed by pressing:



Figure 4.70. Procedure for displaying the Cycle time / cycle time of execution
