According to CPU type, the configuration menu for PLC parameter is different.

 

 

 

 

XPnA CPU and CP3 CPU Type

 

All CIMON CPU Type has below Parameter menu as standard.

Basic, Latch Area Setup, Interrupt and CPU Error manipulation are in PLC Parameter.

 

 

 

 

MP CPU and CP4 CPU Type

 

Communication Port menu is included.

User can set RS232, RS422 and RS485 parameter for CP4C, CP4D and CP4U CPU type.

 

 

 

 

XPnB CPU Type

 

Modbus menu is included and it can be used for XPnB and CM3 CPU type.

 

 

 

 

CM3 CPU type

 

Channel 1, Channel 2, Input Setting, Modbus and Ethernet menu are included.

 

 

 

 

BASIC

 

 

 

 

ACTION

Override the instruction error : CPU keeps running even if there is instruction error in scan program

Allow DO while debugging : Use output while debugging is running. (Default is "Not used")

It does not support CM3 CPU Type.

Asynchronous scan(Timer) : Scan does not match Timer.

 

Timer

Set time unit for Timer instruction.

If Timer is configured as above, T0000~T0127 device has 100ms time unit and T0128~T0511 has 10ms time unit. If 100ms range is 0~-1, all Timer devices become 10ms.

According to CPU type, Timer device range is different.

CPU Type

Timer Range

XP CPU

T0000 ~ T4095

CP CPU

T0000 ~ T1023

CM3 CPU

T0000 ~ T0511

CM2 CPU

T0000 ~ T0255

 

Communication

Permit data writing from remote

  • User can access CPU memory and change the device value by remote access (CICON).

Permit CPU mode change from remote

  • User can change the CPU mode (RUN, STOP, PAUSE) by remote access (CICON).

Enable PLC-Link auto-swap (CPU: XP1R)

  • In Redundancy system, if Primary is failed, Secondary will run automatically.

It is only for XP1R type.

 

Watch Dog Timer

You can set 10ms up to 60000ms to prevent malfunction of scan program.

Designed WDT is longer than scan time, CPU will be reset automatically.

 

Upload

  • Prohibit Program Upload (PLC → PC)

Uploading project file from PLC to CICON is not possible.

 

If you click Online -> Upload(PLC ->  PC) after downloading program to PLC with this function, Error message will pop up as below.

 

 

Hot Restart

If power is ON in designed time, Hot Start Initialization program will run first before scan program.

If CPU does not support RTC, it does not work.

(CM1-CP3A, CM1-CP4A, CM3-SB16MDT and CM3-SB16MDTV do not support Hot Restart)

 

Expansion

If you want to use Expansion Base, choose Base number.

CP3 and XP CPU type support Expansion Base.

 

 

 

Latch Area Setup

 

It is used to save the final value in designed device address after CPU power off.

If you turn CPU on, the final value is still in Latch device.

The Latch device range is different according to CPU Type.

*K device supports Latch as standard.

 

 

Interrupt

 

It is used to make sequence of Periodical Interrupt program.

 

 

 

Periodical Interrupt program must be in Program folder.

 

 

 

Modify Interrupt Program

If you click Modify Interrupt Program, you can set ID, Priority and period of Interrupt.

  • Priority : Number0 is the most priority.

  • Period(msec) range : 10ms ~ 655,350ms

 

 

 

Interrupt instruction

For more details, please refer to Instruction manual.

Cpu Error Manipulation

 

 

User can choose the operating condition of CPU when error occurs on a module.

The features in the red box do not support CM3 CPU type.

 

 

 

 

Communication Port

 

 

 

 

User can set RS232, RS422 and RS485 parameter for CP4C, CP4D and CP4U CPU type.

 

  • Type

Null/RS-422

CM1-CP4C, CM2-BP32MDxx-R : RS232C without modem

CM1-CP4C should use Null/RS-422

CM1-CP4D, CP4U, CM2-BP32MDxx-S:RS422

Modem/RS-485

CM1-CP4C, CM2-BP32MDxx-R:R232C with Modem

CM1-CP4D, CP4U, CM2-BP32MDxx-S:RS485

 

  • Station No.

You can set up from 0 to 31.

 

  • Communication Parameters

This parameter must be the same with connected device.

 

 

 

Input Setting

 

 

*Input Setting is used with CM3 CPU type

 

 

Pulse Input Catch

If you want to use HSC, choose the address

 

Digital Input Filter

The Digital Input Filter is a feature that eliminates noise from input signals. This is useful when on-site condition is noisy or pulse width is an important factor.

By controlling the Digital Input Filter, it can increase the reliability on input pulse. If Input signal is shorter than the pre-defined Digital Input Filter time (value),

this signal is recognized as invalid signal and ignored by module. Digital Input Filter also applies to noisy or chattering pulse

 

The selected address will run by User Input Filter Value.

The unselected address will run by Standard Input Filter Value.

 

The minimum Input Filter value(Time) is 1ms.

 

 

 

Modbus

 

 

Modbus Slave is used with CM3 CPU type.

Choose the starting address for each type.

 

 

 

 

Ethernet

 

 

IP Setting

Type IP address if Ethernet port is used.

Option

If you choose DHCP, IP address is assigned automatically.

CICON Relay Use (Programming Bridge)

When multiple PLC-S are connected over RS232C or RS485(N:N), CICON can provide a communication bridge channel between PLC-S.

DDNS Setting

DDNS setting is used to make a connection between PLC and CIMON SCADA especially when dynamic IP address is assigned to PLC. After setting DDNS Address and port, Site Name (ID) and DDNS Connection Retry must be set up
