1-1-1 Overview

1-1 Overview and Features

1-1-1 Overview

The Ladder Monitor (NS-EXT01) is an application that monitors the ladder program in a SYSMAC CS/CJ-series PLC. The Ladder Monitor enables monitoring the execution status of the ladder program in a connected PLC from a NS-series PT without using a Programming Device (e.g., the CX-Programmer or a Programming Console). Just by switching to the Ladder Monitor from RUN Mode of the PT, the user can monitor the ladder program and I/O in the PLC without changing the system configuration between the NS-series PT and the PLC. Just connect the NS-series PT to a CS/CJ-series PLC with a 1:N NT link, an Ethernet connector, or a Controller Link connection to a registered host, download the project data to the PT, place a Memory Card containing the Ladder Monitor program in the PT, and select Ladder Monitor from the system menu of the PT. The application will start, will monitor the ladder program and I/O of the PLC, and will display the results on the NS-series PT screen.

Note: The Ladder Monitor only monitors the ladder program. It does not have functionality to

change or edit the program. (Force-setting/resetting bits, changing present values, and changing timer/counter set values are enabled for the I/O memory.) In addition, I/O comments can be displayed but symbol names cannot be displayed. Refer to Appendix A-1 Comparison between NS-series PTs and CX-Programmer (page 100) for the differences from CX-Programmer.

Note: The following PT functions will stop when the Ladder Monitor is used.

• System memory communications with the host

• Macros

• Data log

• Alarms

• Operation log

1-1-2 Features

1. The user program can be displayed in ladder form on an NS-series PT (up to 17 rows and 16 columns for the NS12).

2. CS/CJ-series PLCs and NSJ Controllers can be monitored. A CS/CJ-series PLC that is connected to either serial (RS-232C) port A or B of the PT in 1:N NT Link serial communications mode or a PLC connected to the Ethernet port or Controller Link Board of the PT can be monitored.

3. The bit ON/OFF status (i.e., the execution conditions) and present values (words) of the operands of special instructions can be monitored.

4. The desired program section can be specified using the Search Button. Searching is possible for step numbers (program addresses), instructions (selected from a list, including immediate refreshing and differentiation), and instructions with addresses.

5. Jumping from an input bit (“contact”) to the output instruction with the same address (i.e., to a sequence output instruction) is possible (JUMP Search). By repeating this, it is also possible to identify the input bits causing outputs to turn ON and OFF.

6. It is possible to search for input bits that are using the address in an output instruction.

1-1 Overview and Features

1-1-3 Functions Added in Version 2.0

7. In addition to searching for output instructions from input bits and input bits from output instructions, it is also possible to return to the results of up to 30 previous searches.

8. With NS-series PT system version 8.0 or higher, the places where an address

specified as an alarm is used can be automatically found by starting the Ladder Monitor from the Alarm/Event Summary and History on the PT screen.

9. The Multiple I/O Monitor operation can be used to monitor up to 20 (for the NS15)

specified addresses (bits or words).

10. Force-setting/resetting or setting/resetting of a specified bit address can be

performed on the Multiple I/O Monitor Screen.

11. The present value of a specified word address can be changed.

12. Word present values can be displayed and input in hexadecimal, decimal, or signed

decimal.

13. Timer and counter set values can be changed.

14. The operating mode of the PLC (CPU Unit) can be changed.

15. Current errors (non-fatal errors and fatal errors) in the PLC (CPU Unit) can be

displayed. Errors can also be cleared.

16. I/O comments can be read from the PLC. If the I/O comments have been changed, the change will be automatically detected when the Ladder Monitor is started, and it can be selected whether the I/O comments are to be read from the PLC.

17. I/O comments can be displayed in three lines or one line, or not displayed at all. A maximum of five characters can be displayed per line. In addition, comments for addresses selected on the screen can be displayed at the bottom of the screen (up to 71 characters for the NS15, 43 characters for the NS12, or 23 characters for the NS10/8).

18. Ladder Monitor screens can be captured and saved on Memory Cards as bit map files.

1-1-3 Functions Added in Version 2.0

The following functions have been added for Ladder Monitor version 2.
