CV-Series PLC Settings
The following paragraphs describe the features of the PLC Setup component associated with CV-series PLCs.
Refer to
Chapter 4 - PC to PLC Communications for details of transferring PLC setup information to and from the
PLC.
The common Set Default option resets PLC Setup component values to the default settings.
PLC Startup
The PLC Startup tab of the PLC Setup component allows certain PLC settings to be made which always takes
effect on startup (until they are explicitly altered). Some of the options may not be applicable depending on the
device type selected. Use the following procedure to apply settings in the
PLC Startup tab.
1, 2, 3… 3. The status of the Force Status Hold setting, IOM Hold Bit setting and Restart Continuation
Bit setting in the Startup Hold area of the PLC’s Work Area memory can be set so that they
are either maintained or reset to OFF on power up.
4. When power is restored after an interruption, the IO Bits setting and Power-On Status
setting must be selected and the PLC startup mode must be set to Run or Monitor .
5. Set the Mode setting to either Program , Monitor , Run , Debug or Use Programming
Console . The default mode is Program .
6. Set the Display Mode setting. The 7-segment display of the IO Interface units, IO Control
unit and SYSMAC BUS/2 Remote IO Slave units can be set to one of three modes. The
mode is indicated by the position of the decimal point.
♦
Mode 1. Displays the first IO word allocated to the rack (000 indicates an error). This is the
default mode.
♦
Mode 2. Displays the CPU operating status (A or -) and error status
(E, F or -), peripheral connection and rack number.
♦ Mode 3. Displays a 4-character message when the IODP (189) instruction is executed in the
unit’s program.
5.
Check the Automatically Transfer User Program setting to automatically transfer the user
program from one of the PLCs memory cards when the PLC starts-up.
6.
Check the Display modes at startup setting to display all selected modes on startup.
Error Log
The Error Log tab permits certain settings to be applied to error logging. Either Data Memory (DM) or Extended
Memory (EM) areas can be selected to hold the PLC’s Error Log. Refer to Chapter 6 - PLC Error Component for
a description of the Error Log. Use the following procedure to apply settings in the Error Log tab.
1, 2, 3… 1. Check the Enable Error Log setting to enable error logging. If this is not selected, the
default log auxiliary memory is assigned.
2. Enter the Start Address setting for the error log. This is only enabled if the Enable Error
Log setting has been selected.
3. Enter the EM Bank Number setting if the Error Log is to be stored on an installed Extended
Memory Card. The Start Address setting needs to be set to the relevant area of EM. This is
only enabled if the Enable Error Log setting has been selected.
4. Enter the Number of Records setting for the number of records to be held in the PLC Error
component.
Note: An Error Log in the Auxiliary Area (words A100-A199 for CV1000) can contain up to
20 error records. To increase the size of the log (to 2047 records), move it to either the
DM or EM areas.
Execution Controls
Instructions can be executed and peripheral servicing performed by either using:
♦ Event driven (asynchronous) processing mode. The peripheral servicing process interrupts the execution
process cycle by sending IO refresh requests.
or
♦
Synchronised processing mode. The execution and peripheral servicing processes wait for each other to
complete the task in hand.
