*2: User application size is the total file size of control application, Java application, and data. The file size of control applications is up to 10 Mbyte.

Network (Ethernet) Specifications Application

Ethernet is used as the control network, which can be dual redundant, connecting FCNs/FCJs with various PLCs, display units and VDS. FCNs/FCJs are developed and maintained via Ethernet as well.

Communication Specifications

| Connection Destination | Maximum Connections | Remarks | | VDS | 4 | Total of VDSs, FCN/FCJ OPC Servers and FAST/TOOLS | | FCN/FCJ OPC Server | | FAST/TOOLS | | FCN/FCJ | 15 | Number of FCNs/FCJs as connection destinations (*1) | | PLC | 32 | Number of various PLCs such as FA-M3s or MELSECs (*1) |

*1: Number when assigning the destinations one channel each

Note: Compliant with IEEE802.3

Note: For system network configuration and network load, refer to TI 34P02K25-01E “STARDOM Network Configuration Guide.”

Network (Serial) Specifications

Serial ports can be used to link diverse devices and controllers. Communication portfolios facilitating interconnection with display units, various programmable logic controllers, temperature controllers, and power monitors are available via a serial port.

Specifications

• FCJ: two ports (RS-232-C)

• FCN-100:CPU module: one port (RS-232-C) (*1) serial communication module:two ports per module(RS-232-C or RS-422/RS-485) (*2)

Guideline of Control Application Capacity

As a guideline, the capacity of the control application is a total of the following.

(1) Function blocks (POUs)

• Regulator control blocks (e.g., indicator blocks, controller blocks, and manual loaders): Up to 128

• Others (e.g., calculation blocks, switch instrument blocks, and communication POUs): Up to 384

(2) Sequence program

Up to 180 kilosteps in Ladder or up to 128 sequence tables each of which has 32 condition and 32 action rows.

Example of a control application with the maximum size:

• Inputs/outputs: 96 AIs, 32 AOs, 256 DIs, and 256 DOs

• PID loops: 32

• Sequence program: 128 sequence tables

• Control cycle: 1 second

Specification of FCN-100 with Duplexed CPU Modules

• After a failure of the CPU in service, the stand-by CPU obtains the control right instantaneously and resumes control without any influence of the CPU switchover.

• When additionally installing a CPU module to an FCN with a single CPU module to configure duplexed CPU modules, such as when replacing a failed CPU module, carry out the All-program-copy (APC) command for equalization between the CPU modules. It is also possible to run the APC command automatically after CPU replacement. When the APC command is running, the control period lengthens by a second or two only during its first cycle. (*1)

• Synchronization is periodically performed between the in-service CPU and stand-by CPU. The total processing time is hence longer than that of an FCN100 with single CPU.

• If the control application comprises multiple tasks, those tasks cannot access the same global variable.

• The CPU module’s serial port cannot be used.

• Java applications cannot be run.

*1: If one of the two CPUs in dual-redundant configuration is not style-3 NFCP100 CPUs, the APC command cannot be started automatically. In this case, control stops when the APC command is running and the I/O modules operate in the same way as they do when the Fallback option (can be set to ‘hold the output’ or ‘output specified values,’ for example) is selected.

Online Download Function

• Online download function is a feature with which control applications can be modified while a control function continues in operation.

• With this feature, I/Os, variables, data types, program codes, and libraries can be added, deleted or modified.

• Modifying the control loop during system operation does not affect other control loops. Changing a range of control loop or loop connection causes the control loop to become the MAN mode.

Implementation of Java Virtual Machine

• WWW server functionality:

download HTML files and Java applets to Web browsers and access data in FCN-100s and FCJs

• E-mail transmission/reception:

send and receive e-mail using SMTP and POP3 protocols, respectively

support the authentication function of SMTP servers (SMTP Authentication/Pop Before SMTP)
