3: INSTALLATION AND WIRING

Power Supply

Power Supply Voltage

The allowable power voltage range for the slim type Web server CPU module is 20.4 to 26.4V DC.
Power failure detection voltage depends on the quantity of used input and output points. Basically, power failure is

detected when the power voltage drops below 20.4V DC, stopping operation to prevent malfunction.
A momentary power interruption for 10 ms or less is not recognized as a power failure at the rated voltage of 24V DC.

Inrush Current at Powerup

When the slim type CPU module, expansion interface module, or expansion interface slave module is powered up, an
inrush current of a maximum of 50A flows.

Power Supply Wiring

Use a stranded wire of UL1015 AWG22 or UL1007 AWG18 for power supply wiring. Make the power supply wiring as
short as possible.

Run the power supply wiring as far away as possible from motor lines.
For a power supply wiring example of expansion interface modules, see "Power Supply Wiring Example" of the basic

volume (page 2-77).

Grounding

To prevent electrical shocks, connect the terminal to a proper ground using a wire of UL1015 AWG22 or UL1007
AWG18. The grounding also prevents malfunctioning due to noise.

Do not connect the grounding wire in common with the grounding wire of motor equipment.
Separate the grounding wires of the Web server CPU module and external devices which can be a possible noise source.
Use a thick wire for grounding the Web server CPU module and make the grounding wire as short as possible to make

sure that noises from external devices can be conducted to the ground effectively.

• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.

• The allowable power voltage range for the slim type Web server CPU module, expansion interface module
FC5A-EXM2, and expansion interface slave module FC5A-EXM1S is 20.4 to 26.4V DC. Do not use the Web
server CPU module on any other voltage.

• If the power voltage turns on or off very slowly, the Web server CPU module may run and stop repeatedly
or I/O operation may fluctuate at a voltage lower than the rated voltage.

• When Web server CPU module I/O signals are connected to a device which may cause a major accident in
case of an error, take a measure to secure safety, such as providing a voltage monitoring circuit outside the
Web server CPU module.

• Use one power supply to power the CPU module and the expansion interface module or expansion
interface slave module.

• When using a separate power supply, power up the expansion interface module or expansion interface
slave module first, followed by the CPU module, otherwise the CPU module causes an error and cannot
start and stop operation.

• Use an IEC 60127-approved fuse on the power line outside the Web server CPU module. This is required
when equipment containing the Web server CPU module is destined for Europe.

Precautions for Connecting Communication Devices

When connecting communication devices to the Web server CPU module, take possible external noise sources into
consideration.

In a communication network consisting of a Web server CPU module and an external device (a communication device
which has a functional ground and a signal ground connected together internally [for example, IDEC’s HG3F and HG4F
operator interfaces]), if all devices are powered by a common AC or DC power source, noise generated by the external
device may affect the internal circuits of the Web server CPU module and the communication device. Take the following
measures depending on the operating environment.

• Use a separate power supply for the external device generating noises so that a loop circuit to induce noises can not be formed.

• Disconnect the functional ground terminal of the communication device from the ground line. This measure may result in
deterioration of EMC characteristics. When taking this measure, make sure that the EMC characteristics of the entire system are
satisfactory.

• Connect the functional ground terminal of the communication device to the 0V line of the power supply so that the noises from
the external device do not flow through the communication line.

• Connect an isolator to the communication line so that a loop circuit to induce noises can not be formed.

Introduction

This chapter describes the specification and configuration procedure of the maintenance communication server
functions of the Web server CPU module.

Applications

The Web server CPU module features the maintenance communication server functions. WindLDR can monitor the
device values in the Web server CPU module and can also download or upload the user program to or from the Web
server CPU module through the maintenance communication server.

Description of Functions

The Web server CPU module can be configured as a maintenance communication server. The maintenance
communication server can be used simultaneously with other server/client connection communications.

By using the maintenance communication server of the Web server CPU module, the network devices supporting the
maintenance communication, such as touch screens or WindLDR, can read and write the device values in the Web server
CPU module. There is a maximum of three maintenance communication server connections available in the Web server
CPU module as standard. In addition to those 3 connections, a maximum of eight server connections can be configured
as the maintenance communication server. If all server connections are configured as the maintenance communication
server, a total of 11 network devices supporting the maintenance communication can communicate with the Web server
CPU module simultaneously.

The Web server CPU module also supports the pass-through over Modbus RTU. When the Web server CPU module is
configured as Modbus RTU master, it is possible for a remote computer to communicate with FC5A MicroSmart CPU
modules configured as Modbus RTU slaves via the Web Server CPU module. Device values or user programs of those
slaves can be read/written from a remote computer.

The user program can be transferred with the Web server CPU module using the standard maintenance communication
server. However, the user program cannot be transferred using the additional server connections configured as the
maintenance communication server.

Pass-Through over Modbus RTU

The pass-through over Modbus RTU enables you to monitor FC5A MicroSmart CPU modules configured as Modbus RTU
slaves via a Web server CPU module configured as Modbus RTU master from a remote computer. You can remotely read/
write device values or transfer the user programs of the Modbus RTU slaves.

The Web server CPU module with the system program version 1.20 or later can be used as the master of Modbus RTU
pass-through. FC5A MicroSmart CPU modules with the system program version 2.40 or later can be used as the slaves of
Modbus RTU pass-through. The Web server CPU modules (FC5A-K1E/S1E) cannot be used as the slaves.

Ethernet User Communication Overview

The Web server CPU module can be used as an Ethernet user communication client/server. It can be used simultaneously
with the maintenance communication server, Modbus TCP server, and Modbus TCP client.

When using the Web server CPU module user communication server, the client devices can access the Web server CPU
module, and the communication can be performed between the Web server CPU module and the client devices. A
maximum of eight server connections of the Web server CPU module can be allocated to user communication. If all eight
connections are allocated to user communication, a maximum of eight client devices can simultaneously access and
communicate with the Web server CPU module.

When using the Web server CPU module user communication client, the Web server CPU module can access and
communicate with the server devices using the protocol of the server device. A maximum of three client connections of
the Web server CPU module can be allocated to user communication.

User communication client functions and configuration are described in “User Communication Client” on page 8-2. User
communication server functions and configuration are described in “User Communication Server” on page 8-5.

WindLDR version 6.4 or higher is required to use Ethernet user communication.

9: MODBUS TCP COMMUNICATION

Introduction

This chapter describes the Modbus TCP communication of the Web server CPU module. The Web server CPU module can
be used as Modbus TCP client/server. The Web server CPU module can communicate with the devices supporting
Modbus TCP communication on the network.

Modbus TCP Communication Overview

The Web server CPU module can be used as Modbus TCP client/server. Modbus TCP server and client of the Web server
CPU module can be used simultaneously.

When the Web server CPU module is configured as Modbus TCP server, Modbus TCP client devices can access the Web
server CPU module and read and write the data. A maximum of eight server connections can be configured as Modbus
TCP server. If all eight server connections are configured as Modbus TCP server, a maximum of eight Modbus TCP client
devices can access and communicate with the Web server CPU module simultaneously.

When the Web server CPU module is configured as Modbus TCP client, the Web server CPU module can access Modbus
TCP server devices and read or write the data. A maximum of three client connections can be configured as Modbus TCP
client. The Web server CPU module can communicate with multiple Modbus TCP server devices per a client connection.

For the specification and configuration of Modbus TCP client, see “Modbus TCP Client”. For the specification and
configuration of Modbus TCP server, see “Modbus TCP Server” on page 9-7.

Modbus TCP Client

Modbus TCP client communication settings and request tables for Modbus TCP servers can be programmed using the
WindLDR Function Area Settings. The Web server CPU module communicate with the Modbus TCP servers according to
those settings.

Communication with Modbus TCP servers are performed in synchronism with user program execution, and the
communication data are processed at the END processing in the order of request numbers specified in the request table.

Modbus TCP Client Specifications

*1: Specifies the period of time before receiving a response frame from a server.

Parameter Modbus TCP Client

Number of Remote Hosts 255

Slave Number 1 to 247

9-2 WEB SERVER CPU MODULE USER’S MANUAL FC9Y-B1278

Modbus TCP Client Start and Stop

When request execution devices are designated in the Modbus TCP Client request table, internal relays as many as the
request quantity are allocated to execute Modbus TCP Client communication. The internal relays are allocated in the
order of requests. For example, when internal relay M0 is designated as the request execution device, M0 is allocated to
request No. 1, M1 to request No. 2, and so on. To execute a request, turn on the corresponding request execution device.

When communication is completed, the request execution device turns off automatically. When it is required to send
requests continuously, keep the corresponding request execution device on using a SET or OUT instruction.

When request execution devices are not designated, all requests programmed in the request table are executed
continuously.

Communication Completion and Communication Error

Modbus communication finishes when a read or write process is completed successfully or when a communication error
occurs. Communication error occurs when communication failure has repeated three times. When a communication
error occurs, the request is canceled and the next request is transmitted. When the error status data register is
designated, the communication status of each request can be confirmed.

Communication Error Data

When Error Status is configured in the Request Table from the Function Area Settings, the error data of each request can
be confirmed.

Modbus TCP Communication Request Table

A maximum of 255 requests can be configured in the Modbus TCP Client Request Table.

Notes:

• 10 bytes of the user program area are needed per each request.

• Request execution devices and error status data registers are allocated in the order of request numbers. When deleting a
request or changing the order of requests, the relationship of the request to the request execution devices and error status data
register is changed. If the internal relay or data register is used in the user program, the device addresses must be changed
accordingly.

Use a single DR for all

communication requests

Error data of each communication request

Unchecked

Error data, the remote host number (high-order byte) and error code (low-order byte), of each
request in the entire request table can be confirmed. Data registers as many as the quantity of
requests are reserved for storing error data. When an error occurs for a request, an error code is
stored to a corresponding data register.

Checked

A single data register is shared by all requests. When an error occurs for a request, an error code is
stored to the data register and the old value is overwritten.

10: E-MAIL

Introduction

This chapter describes how to use the e-mail functions in the Web server CPU module. The EMAIL instruction sends an
e-mail that is configured in WindLDR.

EMAIL (Send E-mail)

The EMAIL instruction sends an e-mail.

Symbol

Operation Details

When the input to the EMAIL instruction is on, the EMAIL instruction sends an e-mail specified by S1. Once the Web
server CPU module receives a response from the sending e-mail server, the completion output specified by D1 is turned
on, and the operation status (operation transition state and error code) is stored in the device specified by D2. D2+1 is
reserved for the system.

In order to use EMAIL instructions, the e-mail settings, such as e-mail server name, should be configured in the Function
Area Settings. E-mails to send should also be configured in the E-mail Editor dialog box.

The EMAIL instruction is executed when the input to the instruction is on. While the input to the EMAIL instruction is on,
the EMAIL instruction is continuously executed. To avoid executing the EMAIL instruction continuously, a transitional
off-to-on SOTU or on-to-off SOTD instruction should be used.

Valid Devices

*1: Special internal relays cannot be used.

Devices in EMAIL Instruction

S1 (Source 1)

Specify the e-mail number. A constant or data register can be specified.

D1 (Destination 1)

Specify an internal relay or output as the completion output bit. When the Web server CPU module receives a reply from
the sending e-mail server, the completion output bit is turned on. The completion output bit is also turned on when
there is no reply from the sending e-mail server within the timeout.

D2 (Destination 2)

Specify a data register as the operation status. Destination 2 occupies two consecutive data registers starting with the
data register specified by D2. The operation status is stored in D2. D2+1 is reserved for the system. Data registers D0 to
D1998, D2000 to D7998, and D10000 to D49998 can be specified.

Notes:

• When the system program version is 100, do not specify the same e-mail number in multiple EMAIL instructions. When the
system program version is 100 and a data register is specified as S1, do not store the same e-mail number used by the other
EMAIL instructions in the user program to the data register.

• When a data register is specified as S1, do not change the data register value while EMAIL instruction is executed.

The operation status includes the operation transition state (status code) and the error detail (error code). The status
code can be obtained by masking the least 4 bits of the operation status. The error code is stored in the least 4 bits of the
operation status.

Note: If the status code is anything other than the codes listed above, an error of EMAIL instruction is suspected.

Note 1: The detail of the error code 7 is stored in special data register D8457.

Note 2: When converting a data register value fails, ---- is inserted in the e-mail body instead of data register value.

E-mails can be sent to the recipients by the relay of the sending e-mail (SMTP) servers. Even when the value stored in D2
is 64 after the execution of an EMAIL instruction, the recipients of the e-mail may not be able to receive the e-mail if one
of the following conditions is met. The Web server CPU module does not detect such problem.

1. The SMTP server that relays the e-mails is not functioning normally.

2. The e-mail recipient filters the in-coming e-mails by specifying the e-mail address or e-mail domain.
