1. Overview

1.1 Overview of the CIT-200

Communication between maximum 16 blocks of C series and PLC can be carried out via PLC interface unit CIT-200.

The CIT-200 reads and writes the PV, SV or other data from/to the memory in the PLC via a host link unit.

Therefore PLC only needs the program for reading and writing the data in the memory, and this will reduce the communication processing of the PLC.

1.2 Units and structure when applying the CIT-200 to the C series

(1) PLC interface unit: CIT-200

The CIT-200 makes it possible to communicate between multiple blocks (maximum 16 blocks) of C series and the PLC.

7.3 Communication details

How to communicate between the CIT-200 and PLC

After the power to the PLC is turned on, the PLC sets address 0 in the memory to top address to communicate with the CIT, and sets the number of CPT-20A connected to the CIT-200, the number of the CCT-235 connected to the CPT-20A and communication items to the preset addresses (top address to top address+19).

After that, The PLC sets address 1 to 4660 (decimal), and address 2 to 22136 (decimal).

After the power to the CIT-200 is turned on, the CIT-200 continues to read the PLC addresses (0 to 2).

After confirming that address 1 is 4660 (decimal) and address 2 is 22136 (decimal), the CIT-200 reads the data of the addresses (top address to top address+19) in address 0.

Note

• Memory type is decided beforehand depending on the PLC selected by the Rotary switch. (pp. 9-10)

To address 0 of the predetermined memory, set the top address in the memory which is used for communications with the CIT-200.

• The CIT-200 directly reads from and writes to the data memory of the PLC, therefore the PLC does not need to manage the communication procedure, and the program can be simplified.

• With writing to and reading from the PLC, the amount of data processed at a time is 20 channels per item.

• Communication protocol is Format 4, word unit (command W).

Processing in the PLC

Setting value change flag setting

The following procedures show how to change setting values from the PLC. See (Fig.7.3-1).

(1) When changing the CCT-235 setting value, the PLC sets the setting value change flag from the following

(1 to 8) items.

1. All setting values

2. Main setting value

3. Alarm 1, Alarm 2, Heater burnout alarm

4. Main proportional band, Integral time, Derivative time, Cooling proportional band, Overlap/Dead band

5. Auto-tuning

6. Control action (Perform/Stop)

7. Alarm 1 and Alarm 2 action selection, Main proportional cycle, Cooling proportional cycle

8. Control output high limit, low limit.

(2) After the CIT-200 reads the contents of the setting value change flag (3), the CIT-200 sets them to the CCT-235 via the CPT-20A (4).

(5) After that, the CIT-200 sets the value of the setting value change flag to “0”.

The setting data in the data memory should be set within the setting range of CCT-235 since the

CIT-200 does not check the allowable setting range of the data.

PLC

(1) Sets the setting value

change flag to (1 to 8).

(6) The setting value

change flag is set to 0.

CIT-200

(2) Reads the setting

value change flag.

(3) Reads setting

values from the PLC.

(4) Sets the setting values

of (3) to the CPT-20A.

(5) Writes the setting

value change flag to 0.

CPT-20A

Sets the setting values

to each CCT-235.

CCT-235

Changes the setting values.

• PV reading

After the CIT-200 reads PV from the CCT-235, the CIT-200 writes the PV to the PLC memory area where

“PV (input) reading” is assigned.

Notice

The CIT-200 can monitor the temperature of up to 16 blocks (320 points). However, if the CIT-200 reads or writes the number of data exceeding the PLC data memory capacity, communication errors occur and it does not work normally.

Therefore, the number of data of the CIT-200 has to be within PLC data memory capacity.

For the PLC data memory capacity, refer to the Instruction manual for each PLC.

8.2 Initial setting of Host link unit (C200H-LK202-V1)

When communicating with the C series, set the addresses from the PLC to store the setting item data of the C series after the power supply to the PLC is turned on.

Communication is impossible if the addresses for storing the setting item data of the C series are not set.

Set the program referring to the sample program (Fig.8.2-1) as follows.

(Execute only the first scan of the following sample program.)

Note

Leave file memory addresses (DM0000 to DM0002) of the PLC vacant when setting the program since the addresses (DM0000 to DM0002) are used for the top address for the temperature control.

8.3 Communication details

How to communicate between the CIT-200 and Host link unit (C200H-LK202-V1)

After the power to the PLC is turned on, the PLC sets address 0 in the memory area to top address and sets the number of CPT-20A units connected to the CIT-200, the number of the CCT-235 units connected to the CPT-20A and communication items to the preset addresses (top address to top address+19).

After that, The PLC sets address 1 to 4660 (decimal), and address 2 to 22136 (decimal).

After the power to the CIT-200 is turned on, the CIT-200 continues to read the PLC address (0 to 2).

After confirming that address 1 is 4660 (decimal) and address 2 is 22136 (decimal), the CIT-200 reads the data of the addresses (top address to top address+19) in address 0.

Note

• Memory type is decided beforehand depending on the PLC selected by the Rotary switch.

To the address 0 of the predetermined memory, set the top address in the memory area which is used for communications with the CIT-200.

• The CIT-200 directly reads from and writes to the data memory of the PLC, therefore the PLC does not need to manage the communication procedure, and the program can be simplified.

• With writing to and reading from the PLC, the amount of data processed at a time is 20 channels per item.

9.2 Initial setting of Interface module (NC1L-RS4)

(1) Define the user file area with system definition (File number: W30, File range: Number of data which is required for the communication, Data format: SI).

For more details, refer to Fuji Users' manual [Command] for Program controller (MICREX-F).

(2) When communicating with the C series, set the program to the PLC to perform initial setting

(addresses to store the C series setting item data) of one (1) scan after the power supply to the PLC is turned on.

Communication is impossible if the initial setting (addresses to store the C series setting item data) is not performed.

Note

Leave the PLC file memory addresses (W30.0000 to W30.0002) vacant since these will be used for

the top address for the temperature control.

9.3 Communication details

How to communicate between the CIT-200 and Interface module (NC1L-RS4)

The CIT-200 sets the CCT-235 to parameters via the CPT-20A after reading the PLC data memory through the Interface module (NC1L-RS4).

The CIT-200 constantly monitors the CCT-235 via the CPT-20A and writes its status to the PLC data memory.

After the power to the PLC is turned on, the PLC sets address 0 in the memory to top address for use of the communication with the CIT-200. The PLC sets the preset addresses (top address to top address +19) to the number of CPT-20A units connected to the CIT-200, the number of CCT-235 units connected to the CPT-20A and communication items.

After that, the PLC sets address 1 to 4660 (decimal) and address 2 to 22136 (decimal).

After the power to the CIT-200 is turned on, the CIT-200 continues to read the PLC addresses (0 to 2).

After confirming that address 1 is 4660 (decimal) and address 2 is 22136 (decimal), the CIT-200 reads data of the addresses (top address to address +19) which has been set in address 0.

File memory "W30 and those which follow it" area is used for writing/reading address of the data.

(It is necessary to set the file memory area from the PLC side)

For more details, refer to Fuji Users' manual [Command] for Program controller (MICREX-F).

Note

• Memory type is decided beforehand depending on the PLC selected by the Rotary switch.

To the address 0 of the predetermined memory, set the top address in the memory which is used for communications with the CPT-20A.

• The CIT-200 directly reads from and writes to the data memory of the PLC, therefore the PLC does not need to manage the communication procedure, and the program can be simplified.

• With writing to and reading from the PLC, the amount of data processed at a time is 20 channels per item.

All communication items: Used

To the address W30.1000, 16 0 (lower 4-bit), set the number of CPT-20A units connected to the CIT-200.

To the addresses [W30.1001 to W30.1004], set the number of CCT-235 units connected to the CPT-20A.

To the addresses [W30.1005 to W30.1007], select the communication item Used or Not used.

To the address W30.1008, set the signal (setting value change flag) sending the value from the PLC to the CCT-235.

The addresses [W30.1009 to W30.1019] are used for future extension.

To the address W30.1020 and those which follow it, set the necessary points of the communication items

(from the main setting value in sequence) to the addresses. The communication items have been set at the addresses [W30.1005 to W30.1007].

However, the communication items which have not been set at the addresses [W30.1005 to W30.1007] will not be assigned to addresses.
