Supplementary Descriptions of the Special Data Registers Related to the Communication Functions

■ D8026: Communication Mode Information (Port 1 to 3)

This register indicates communication mode information for Port 1 to Port 3. The allocation of communication ports in the device (bit assignment) is as follows.

■ D8030: Communication Adapter Information

This register indicates information about the communication cartridges in Port 2 and Port 3. The allocation of communication ports in the device (bit assignment) is as follows.

■ D8052: J1939 Communication Error Code

When an error occurs in J1939 communication, the error code is written to this register. For details on J1939 communication error codes, see "J1939 Communication Error Code (D8052)" on page 8-5.

■ D8069 to D8099: Slave (1 to 31) Communication Status/Error

Special data registers used in data link communication. For details, see "Master Station" on page 7-4.

■ D8100, D8102, D8103: Slave Number (Port 1 to 3)

The slave number is written to these registers when the Port 1 to 3 communication mode is maintenance communication, Modbus RTU slave, or data link communication. The slave number can be changed by changing the value of D8100, D8102, and D8103 in Function Area Settings D8100 = Port 1 Slave No. D8102 = Port 2 Slave No. D8103 = Port 3 Slave No. For details on communication modes, see the following in this manual.

• Maintenance communication: "Maintenance Communication" on page 4-1

• Modbus RTU slave: "Modbus Communication" on page 6-1

• Data link communication: "Data Link Communication" on page 7-1

0 (000): The DSR signal status is not used for FC6A Series MicroSmart transmission control.

Use this status when DSR signal control is not required.

1 (001): When the DSR signal is on, the FC6A Series MicroSmart can transmit and receive.

2 (010): When the DSR signal is off, the FC6A Series MicroSmart can transmit and receive.

3 (011): When the DSR signal is on, transmission is possible (reception is always possible).

This is normally called "busy control" and is used for transmission control for devices with a slow processing speed such as printers.

(As viewed from the connected device, there is a limit on the data that can be input.)

4 (100): When the DSR signal is off, transmission is possible.

5 or higher: The operation is the same as the setting "000".

5. Click OK.

This concludes configuring the settings.

Adjusting the time zone (D8413)

The selected time zone (GMT-12:00 to GMT+13:00) can be adjusted in 15 minute increments with the value of special data register D8413 (time zone offset).

For example, if GMT+09:00 is selected, storing +1 in D8413 advances the time by 15 minutes to make the time zone "GMT+09:15". Storing -2 in D8413 sets the time back by -30 minutes to make the time zone "GMT+08:30".

Checking the operation status (D8414)

The SNTP Operation Status is stored in special data register D8414 (SNTP Operation Status). The operation status indicates the operation status (status code) and the error details (error code).

The operation status (status code) is stored in the upper 12 bits of D8414 and the error details (error code) is stored in the lower 4 bits of D8414.

Acquire the current time at an arbitrary timing (M8191)

When special internal relay M8191 (SNTP time acquisition flag) is turned on, the current time is acquired from the SNTP server.

Elapsed time since acquiring the current time (D8415)

The elapsed time (0 to 65,535) in minutes since last acquiring the current time from the SNTP server is stored in special data register D8415 (elapsed time since SNTP access). Since the values that can be stored are between 0 and 65,535, 65,535 minutes / 60 minutes / 24 hours = approximately 45 days, so the maximum value that can be measured is 45 days.

For example, when the date and time that the current time was last acquired from the SNTP server is January 1 at 12:00, if the value of D8415 is checked on January 1 at 15:00, the value stored is "180" because 3 hours = 180 minutes have elapsed.

D8145 is reset to 0 when the current time is successfully acquired, then the elapsed time count starts. If acquiring the current time from the SNTP server was not successful even once, the value of D8145 is not updated.

Auto Ping Function

This section describes the auto ping function that periodically pings the specified remote host.

Function Description

The function to periodically ping the specified remote host is called the auto ping function. This function can be used to check whether or not communication is possible with the specified remote host by sending a packet to that host.

The remote host is specified with the remote host list.

When auto ping is enabled and immediately after auto ping is enabled due to the FC6A Series MicroSmart power being turned on and a change in the user program, auto ping execution starts and the specified remote host numbers are pinged in order from the smallest number. There is no impact on the FC6A run and stop statuses and the ladder program. Auto ping is stopped while M8187 (auto ping stop flag) is on. When M8187 is turned off, auto ping execution starts.

The results of the auto ping function can be linked with Modbus TCP client request processing. For linking with Modbus TCP clients, see "Modbus TCP Client" on page 6-19.

When M8187 (auto ping stop flag) is turned from off to on, or when the user program is changed and the auto ping function is set from "Used" to "Not used", the internal relay on/off status immediately before that is kept. When M8187 (auto ping stop flag) is turned from on to off, or when the user program is changed and the auto ping function is set from "Not used" to "Used", the internal relays are all turned off. There is no impact on the operation of the PING instruction.

Specify the data register that stores the operation status of the ping sent with the auto ping function. If a data register is entered, the range of data registers that will be used is displayed on the right side. The operation status indicates the operation status (status code) and the error details (error code). The status code is stored in the upper 12 bits and the error code is stored in the lower 4 bits.

Introduction

This chapter describes user communication to send and receive specific data by converting it to data types for external devices connected to the FC6A Series MicroSmart.

The user communication instructions are used to execute user communication.

The user communication instructions differ according to the communication interface that will be used.

• When performing user communication with an external device using port 1 to port 3 via serial communication (RS232C/RS485)

"TXD (Transmit)" on page 5-2 "RXD (Receive)" on page 5-10

• When performing user communication with an external device using Ethernet port 1 via Ethernet communication

"ETXD (User Communication Transmit over Ethernet)" on page 5-23 "ERXD (User Communication Receive over Ethernet)" on page 5-23

User communication allows the following two types of communication methods:

• Serial communication with an external device connected to port 1 to port 3 (RS232C/RS485)

• Ethernet communication with an external device connected by the Ethernet port 1

For valid device address ranges, see Chapter 2 "Device Addresses" in the "FC6A Series MicroSmart LAD Programming Manual".

*1 Internal relays M0 through M7997 or M10000 through M17497 can be designated as D1. Special internal relays cannot be designated as D1. *2 Special data registers cannot be used.

Transmit data designated by device S1 can be a maximum of 1,536 bytes.

When transmission is complete, an output or internal relay, designated by device D1, is turned on.

Destination 2 occupies two consecutive data registers starting with the device designated by D2. The transmit status data register, D0000-D7998 and D10000-D55998, stores the status of transmission and error code. The next data register stores the byte count of transmitted data. The same data registers cannot be used as transmit status registers for TXD1 through TXD3 instructions and receive status registers for RXD1 through RXD3 instructions.

The TXD instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see Chapter 3 "User Program Execution Errors" in the "FC6A Series MicroSmart LAD Programming Manual".

——

Precautions for Programming TXD Instruction

• The FC6A Series MicroSmart has five formatting areas each for executing TXD1 through TXD3 instructions, so five instructions each of TXD1 through TXD3 can be processed at the same time. If inputs to more than five of the same TXD instructions are turned on at the same time, an error code is set to the transmit status data register, designated by device D2, in the excessive TXD instructions that cannot be executed.

• If the input for a TXD instruction turns on on while another TXD instruction is executed, the subsequent TXD instruction is executed 2 scan times after the preceding TXD instruction is completed.

• Since TXD instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

• The data register used to store the transmit/receive status and the transmit/receive data byte count must be different for the TXD instruction and the RXD

instruction.

• The TXD instruction cannot be used in an interrupt program. If used, a user program execution error occurs, the execution of the instruction is canceled, and the next instruction is executed. For details about the user program execution errors, see Chapter 3 "User Program Execution Errors" in the "FC6A Series MicroSmart LAD Programming Manual".

Designating Data Register as S1

When a data register is designated as source device S1, conversion type and transmit digits must also be assigned. The data stored in the designated data register is converted and the assigned quantity of digits of the resultant data is transmitted. The conversion types that are available are: Binary to ASCII, BCD to ASCII, and no conversion.

When repeat is designated, data of data registers as many as the repeat cycles are transmitted, starting with the designated data register. Repeat cycles can be up to 99.

Conversion Type

The transmit data is converted according to the designated conversion type as described below:

Example: D10 stores 000Ch (12)

(1) Binary to ASCII conversion

(2) BCD to ASCII conversion

(3) No conversion

Transmit Digits (Bytes)

After conversion, the transmit data is taken out in specified digits. Possible digits depend on the selected conversion type.

Example: D10 stores 010Ch (268)

(1) Binary to ASCII conversion, Transmit digits = 2

(2) BCD to ASCII conversion, Transmit digits = 3

(3) No conversion, Transmit digits = 1

BCC Calculation Start Position

The start position for the BCC calculation can be specified from the first byte through the 15th byte. The BCC is calculated for the range starting at the designated position up to the byte immediately before the BCC of the transmit data.

Example: Transmit data consists of 17 bytes plus 2 BCC digits.

(1) Calculation start position = 1

(2) Calculation start position = 2

BCC Calculation Formula

BCC calculation formula can be selected from XOR (exclusive OR), ADD (addition), ADD-2comp, Modbus ASCII, or Modbus RTU.

Example: Conversion results of transmit data consist of 41h, 42h, 43h, and 44h.

(1) BCC calculation formula = XOR

Calculation result = 41h ⊕ 42h ⊕ 43h ⊕ 44h = 04h

(2) BCC calculation formula = ADD

Calculation result = 41h + 42h + 43h + 44h = 10Ah → 0Ah (Only the last 1 or 2 digits are used as BCC.)

(3) BCC calculation formula = ADD-2comp

Calculation result = FEh, F6h (2 digits without conversion)

(4) BCC calculation formula = Modbus ASCII

Calculation result = 88 (ASCII)

(5) BCC calculation formula = Modbus RTU

Calculation result = 85h 0Fh (binary)

*1 Internal relays M0 through M7997 or M10000 through M17497 can be designated as D1. Special internal relays cannot be designated as D1. *2 Special data registers cannot be used.

Receive format designated by device S1 can be a maximum of 1,536 bytes.

When data receive is complete, an output or internal relay, designated by device D1, is turned on.

Destination 2 occupies two consecutive data registers starting with the device designated by D2. The receive status data register, D0000-D7998 or D10000-D55998, stores the status of data receive and error code. The next data register stores the byte count of received data. The same data registers can not be used as transmit status registers for TXD1 through TXD3 instructions and receive status registers for RXD1 through RXD3 instructions.

The RXD instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see Chapter 3 "User Program Execution Errors" in the "FC6A Series MicroSmart LAD Programming Manual".

——

Precautions for Programming the RXD Instruction

• The FC6A Series MicroSmart can execute a maximum of five instructions each of RXD1 through RXD3 that have a start delimiter at the same

time. If a start delimiter is not programmed in RXD1 through RXD3 instructions, the FC6A Series MicroSmart can execute only one instruction each of RXD1 through RXD3 at a time. If the start input for a RXD1 through RXD3 instruction is turned on while another RXD1 through RXD3 instruction, without a start delimiter is executed, a user communication error occurs.

• Since RXD instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

• Once the input to the RXD instruction is turned on, the RXD is activated and ready for receiving incoming communication even after the input is

turned off. When the RXD completes data receiving, the RXD is deactivated if the input to the RXD is off. Or, if the input is on, the RXD is made ready for receiving another communication. Special internal relays are available to deactivate all RXD instructions waiting for incoming communication. For user communication receive instruction cancel flags, see "User Communication Receive Instruction Cancel Flag" on page 5-22.

Receive Format

Receive format, designated by source device S1, specifies data registers to store received data, data digits for storing data, data conversion type, and repeat cycles. A start delimiter and an end delimiter can be included in the receive format to discriminate valid incoming communication. When some characters in the received data are not needed, “skip” can be used to ignore a specified number of characters. BCC code can also be appended to the receive format to verify the received data. One RXD instruction can receive 200 bytes of data at the maximum.

Designating Data Register as S1

When a data register is designated as source device S1, receive digits and conversion type must also be assigned. The received data is divided into blocks of specified receive digits, converted in a specified conversion type, and stored to the designated data registers. Conversion types are available in ASCII to Binary, ASCII to BCD, and no conversion.

When repeat is designated, received data is divided, converted, and stored into as many data registers as the repeat cycles, starting with the designated data register. There can be up to 99 repeat cycles.

When a data register is designated as source device S1, a delimiter can be included in the data register designation to end receiving communication.

Receive Digits

The received data is divided into blocks of specified receive digits before conversion as described below:

Example: Received data of 6 bytes are divided in different receive digits. (Repeat is also designated.)

(1) Receive digits = 2 (2) Receive digits = 3

Conversion Type

The data block of the specified receive digits is then converted according to the designated conversion type as described below:

Example: Received data has been divided into a 2-digit block.

(1) ASCII to Binary conversion

(2) ASCII to BCD conversion

(3) No conversion

Repeat Cycles

When a data register is assigned to repeat, the received data is divided and converted in the same way as specified, and the converted data is stored to as many consecutive data registers as repeat cycles.

Example: Received data of 6 bytes is divided into 2-digit blocks, converted in ASCII to Binary, and stored to data registers starting at D20.

(1) Repeat cycles = 2

Delimiter

A delimiter for the data register in the receive format can be assigned. Using a delimiter, incoming data of variable length can be received and stored to data registers.

Delimiter How the incoming data is stored to data registers

No delimiter

Note: Delimiters for data registers can be used in the receive format of RXD instructions only.

The incoming data is stored to data registers until all the data specified with receive digits, conversion type, and repeat is processed or the specified delimiter is received.

The incoming data is stored to data registers until all the data specified with receive digits, conversion type, and repeat is processed.

Designating Constant as Start Delimiter

A start delimiter can be programmed at the first byte in the receive format of a RXD instruction; the FC6A Series MicroSmart will recognize the beginning of valid communication, although a RXD instruction without a start delimiter can also be executed.

When a constant value is designated at the first byte of source device S1, the one-byte data serves as a start delimiter to start the processing of the received data.

A maximum of five instructions each of RXD1 through RXD3 with different start delimiters can be executed at the same time. When the first byte of the incoming data matches the start delimiter of a RXD instruction, the received data is processed and stored according to the receive format specified in the RXD instruction. If the first byte of the incoming data does not match the start delimiter of any RXD instruction that is executed, the FC6A Series MicroSmart discards the incoming data and waits for the next communication.

When a RXD instruction without a start delimiter is executed, any incoming data is processed continuously according to the receive format. Only one instruction each of RXD1 through RXD3 without a start delimiter can be executed at a time. If start inputs to two or more RXD instructions without a start delimiter are turned on simultaneously, the one at the smallest address is executed and the corresponding completion output is turned on.

Example:

(1) When a RXD instruction without a start delimiter is executed

(2) When RXD instructions with start delimiters STX (02h) and ENQ (05h) are executed

Multi-byte Start Delimiter

A start delimiter can be programmed at the first bytes in the receive format of a RXD instruction; the FC6A Series MicroSmart will recognize the beginning of valid communication, although a RXD instruction without a start delimiter can also be executed. A maximum of 5 consecutive constants that are either character or hexadecimal from the first byte of the receive format are considered a multi-byte start delimiter.

If a RXD instruction with a start delimiter is executed and another RXD instruction with the same start delimiter is executed, user communication error code 5 is stored in the data register designated as the receive status of the second RXD instruction. When the error occurs, the second RXD instruction is canceled, and the first RXD instruction executed is kept.

If a multi-byte start delimiter is assigned, and the incoming data does not match the entire multi-byte start delimiter, the FC6A Series MicroSmart discards the incoming data and waits for the next communication.

When the first one byte is received, a timer is started to monitor the interval between incoming data even when a multi-byte start delimiter is assigned. If data is not received in the period specified for the receive timeout value after receiving one byte of data, a receive timeout error occurs, and user communication error code 11 is stored in the status data register.

Examples: Multi-byte Start Delimiter

Multi-byte start delimiter is determined in the structure of the Receive Format. The following examples show how multi-byte start delimiter is determined.

• Constants are followed by data register, skip, or BCC

Note: Constants following data register, skip, or BCC are not considered start delimiter even if these are in the first five bytes of the receive format.

• More than 5 constants are specified from the first byte

Note: Constants that are neither start delimiters or end delimiters are considered constants for verification. See "Constant for Verification" on page 5-17.

Example: Start Delimiter Duplication Error

When input I0 is turned on, the first RXD instruction is executed and status code 32 is stored in the receive status D200, indicating the RXD instruction is waiting for the incoming data. When input I1 is turned on, another RXD instruction is executed, but since two RXD instructions have the same start delimiter, the second RXD instruction is not executed, and user communication error code 5 is stored in the receive status D300.

SER COMMUNICATION INSTRUCTIONS

Note: If you execute two or more RXD instructions with multi-byte start delimiters simultaneously, the start delimiters of those RXD instructions

must be unique from the others. When the length of the multi-byte start delimiters of the RXD instructions is different, the length of the shortest one is applied to check the duplicated start delimiters. The start delimiter of any of two RXD instructions in the following RXD instructions are considered the same.

Example: Using Multi-byte Start Delimiter

The following example shows the advantages of using a multi-byte start delimiter rather than a single-byte start delimiter. A RXD instruction processes incoming data from the master station. The incoming data is sent to multiple slave stations 0 through 9, and the local slave station number is 1. Therefore, incoming data from the master station must be received only when the incoming data is sent for the slave station 1.

• Incoming data

Incoming data consists of start delimiter STX, a slave station number which can be 0 through 9, data 0000 through 9999, and end delimiter CR.

• Single-byte start delimiter

Only the first byte can be the start delimiter. The second byte of the incoming data, which is the slave station number, has to be stored to data register D0, and extra ladder programming is needed to see whether the slave station number of the incoming communication is 1 or not. Only when the slave station number is 1, received data stored in D1 is valid for the local PLC.

SER COMMUNICATION INSTRUCTIONS

• Multi-byte start delimiter

First two bytes can be configured as a multi-byte start delimiter. The incoming data is processed according to the receive format only when the first two bytes of the incoming data match the start delimiter. Therefore, only the incoming data sent to slave station 1 is processed. No extra ladder programming is needed to check the slave station number.

Designating Constant as End Delimiter

An end delimiter can be programmed at the end of the receive format of a RXD instruction; the FC6A Series MicroSmart will recognize the end of valid communication, although RXD instructions without an end delimiter can also be executed.

When a constant value is designated at the end of source device S1, the one-byte data serves as an end delimiter to end the processing of the received data. If data bits are set to 7 bits, the end delimiters will be between 00h and 7Fh. If data bits are set to 8 bits, the end delimiters will be between 00h and FFh. Constant values are entered in character or hexadecimal notation into the source data. When using the same RXD instruction repeatedly in a user program, assign different end delimiters for each RXD instruction.

If a character in incoming data matches the end delimiter, the RXD instruction ends receiving data at this point and starts subsequent receive processing as specified. Even if a character matches the end delimiter at a position earlier than expected, the RXD instruction ends receiving data there.

If a BCC code is included in the receive format of a RXD instruction, an end delimiter can be positioned immediately before or after the BCC code. If a data register or skip is designated between the BCC and end delimiter, correct receiving is not ensured.

When a RXD instruction without an end delimiter is executed, data receiving ends when the specified bytes of data in the receive format, such as data registers and skips, have been received. In addition, data receiving also ends when the interval between incoming data characters exceeds the receive timeout value specified in the Communication Parameters dialog box whether the RXD has an end delimiter or not. The character interval timer is started when the first character of incoming communication is received and restarted each time the next character is received. When a character is not received within a predetermined period of time, timeout occurs and the RXD ends data receive operation.

Example:

(1) When a RXD instruction without an end delimiter is executed

(2) When a RXD instruction with end delimiter ETX (03h) and without BCC is executed

Constant for Verification

Constants excluding start and end delimiters can be configured in the receive format to verify the incoming data with the constants, which are either characters or hexadecimal values. As many constants can be configured for the verification as required. The verification result is stored in the receive status of the RXD instruction.

Example: Programming Constant for Verification

The following example shows the advantage of using constant for verification. The incoming data contains a constant value “1” in the middle, and that constant value needs to be verified to see whether the incoming data is valid.

• Using Data Register

The incoming data including the constant value needs to be stored in data registers. When the RXD instruction completes receiving the incoming data, the receive status contains 64, meaning the RXD instruction has completed without errors, even if the constant value is not an expected value. Extra ladder programming is needed to see whether the constant value in the incoming data is correct or not.

• Using Constant for Verification

A constant to verify the constant value in the incoming data is designated in the receive format. If the constant value is not an expected value when the RXD instruction completes receiving the incoming data, the receive status contains 74, meaning the RXD instruction has completed but user communication error code 5 occurred. No extra ladder programming is needed to see whether the constant value in the received data is correct or not.

Note: When configuring constants, which are either characters or hexadecimal values, in the receive format, and the incoming data does not match the constants in the receive format, then a user communication error code is stored in the receive status. The error code contained in the receive status depends on whether the constants are used as a start delimiter or as constants for verification. If used as a start delimiter, user communication error code 7 is stored in the receive status, and the RXD instruction keeps waiting for valid incoming data. On the other hand, if used as constants for verification, the receive status contains 74, and the RXD instruction finishes the execution. To repeat receiving incoming communication, turn on the input for the RXD instruction.

BCC (Block Check Character)

The FC6A Series MicroSmart has an automatic BCC calculation function to detect a communication error in incoming data. If a BCC code is designated in the receive format of a RXD instruction, the FC6A Series MicroSmart calculates a BCC value for a specified starting position through the position immediately preceding the BBC. It then compares the calculation result with the BCC code in the received incoming data. The start position for the BCC calculation can be specified from the first byte through the 15th byte. The BCC can be 1 or 2 digits.

When an end delimiter is not used in the RXD instruction, the BCC code must be positioned at the end of the receive format designated in Source 1 device. When an end delimiter is used, the BCC code must be immediately before or after the end delimiter. The FC6A Series MicroSmart reads a specified number of BCC digits in the incoming data according to the receive format to calculate and compare the received BCC code with the BCC calculation results.

BCC Calculation Start Position

Example: Received data consists of 17 bytes plus 2 BCC digits.

(1) Calculation start position = 1

BCC calculation formula can be selected from XOR (exclusive OR), ADD (addition), ADD-2comp, Modbus ASCII, or Modbus RTU.

Example: Incoming data consists of 41h, 42h, 43h, and 44h.

(1) BCC calculation formula = XOR

Calculation result = 41h ⊕ 42h ⊕ 43h ⊕ 44h = 04h

(2) BCC calculation formula = ADD

Calculation result = 41h + 42h + 43h + 44h = 10Ah → 0Ah (Only the last 1 or 2 digits are used as BCC.)

(3) BCC calculation formula = ADD-2comp

Calculation result = FEh, F6h (2 digits without conversion)

(4) BCC calculation formula = Modbus ASCII

Calculation result = 88 (ASCII)

(5) BCC calculation formula = Modbus RTU

Calculation result = 85h 0Fh (binary)

Conversion Type

The BCC calculation result can be converted or not according to the assigned conversion type as described below:

Example: BCC calculation result is 0041h.

(1) Binary to ASCII conversion

Note: On WindLDR, Modbus ASCII defaults to binary to ASCII conversion.

(2) No conversion

Note: On WindLDR, Modbus RTU defaults to no conversion.

BCC Digits (Bytes)

The quantity of digits (bytes) of the BCC code can be selected from 1 or 2.

Example:

Note: On WindLDR, Modbus ASCII and Modbus RTU

default is set to 2 digits.

Comparing BCC Codes

The FC6A Series MicroSmart compares the BCC calculation result with the BCC code in the received incoming data to check for any error in the incoming communication due to external noises or other causes. If a disparity is found in the comparison, an error code is stored in the data register designated as receive status in the RXD instruction. For user communication error code, see "User Communication Error" on page 5-43.

Example 1: BCC is calculated for the first byte through the sixth byte using the XOR format, converted in binary to ASCII, and compared with the BCC code appended to the seventh and eighth bytes of the incoming data.

Example 2: BCC is calculated for the first byte through the sixth byte using the ADD format, converted in binary to ASCII, and compared with the BCC code appended to the seventh and eighth bytes of the incoming data.

SER COMMUNICATION INSTRUCTIONS

D1 (Destination 1)

Set an internal relay or an output for the receive completion output. When the start input for a RXD instruction is turned on, preparation for receiving data is initiated, followed by data conversion and storage. When the data receive operation sequence

is complete, the designated output or internal relay is turned on.

Conditions for Completion of Receiving Data

After starting to receive data, the RXD instruction can be completed in three ways depending on the designation of end delimiter and delimiter in the receive format.

End Delimiter Delimiter Conditions for Completion of Receiving Data

With With or Without

Without With

Without Without When a specified byte count of data (digits × repeat) has been received.

Note: Whenever a receive timeout has occurred, data receiving stops arbitrarily. Data receiving is complete when one of the above three conditions is met. To abort a RXD instruction, use the special internal relay for user communication receive instruction cancel flag. See "User Communication Receive Instruction Cancel Flag" on page 5-22.

Example:

A RXD instruction does not have an end delimiter and has a delimiter programmed in the receive format for data registers.

When a specified byte count of data (digits × repeat) has been received or when an end delimiter is received. When a BCC exists immediately after the end delimiter, the BCC is received before ending data receiving.

After the last constant (including delimiter) designated in the RXD instruction has been received, data receiving is completed when the subsequent byte count of data has been received.

D2 (Destination 2)

Set the data register in which to store the receive status and the receive data byte count. The receive status is stored in D2+0 and the receive data byte count is stored in D2+1. Data registers D0000 through D7998 and D10000 through D55998 can be set.

D2+0 (Receive Status)

The receive status is stored in the data register set with D2. The receive status includes the reception operation status and the error information.

Status Description

From turning on the start input for a RXD instruction to read the receive format, until the RXD instruction is enabled by an END processing

From enabling the RXD instruction by an END processing, until incoming data is received

From receiving incoming data, until the received data is converted and stored in data registers according to the receive format

RXD instructions are cancelled by special internal relay for user communication receive instruction cancel flag, such as M8022, M8023 or M8026

If the receive status code is other than shown above, a receive instruction error is suspected. See "User Communication Error" on page 5-43.

D2+1 (Receive Digits (Bytes))

The data register next to the device designated for receive status stores the byte count of data received by the RXD instruction. When a start delimiter, end delimiter, and BCC are included in the received data, the byte counts for these codes are also included in the receive data byte count.

Example: Data register D200 is designated as a device for receive status.

User Communication Receive Instruction Cancel Flag

If user communication receive instruction cancel is turned on when the receive pre-processing for the user communication receive instruction has already been completed and data is being received (status code 32), all receive instructions for the corresponding port will be canceled. This is effective for canceling receive instruction execution when waiting a long time to receive data. To activate a receive instruction that was canceled, turn off the user communication receive instruction cancel flag, and then turn on the receive instruction input conditions again. User communication receive instruction cancel flags are allocated as follows to each communication port as a special internal relay.

"R/W" is the abbreviation for read/write. When R/W, it can be read and written. When R, it can only be read. When W, it can only be written.

SER COMMUNICATION INSTRUCTIONS

ETXD (User Communication Transmit over Ethernet)

The ETXD instruction converts transmission data to the specified data type and sends it to the external device connected over Ethernet.

When the input is on, the transmission data designated by S1 is transmitted to the device connected with the specified connection.

When transmission is complete, the device designated by D1 is turned on. Transmit status (the transmission status and error code) is stored to the device designated by D2.

The byte count of transmitted data is stored to D2+1.

Apart from the connection settings, the settings of ETXD and TXD instructions are the same. For details on TXD instruction, see "TXD (Transmit)" on page 5-2.

The ETXD instruction cannot be used in an interrupt program.

If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the FC6A Series MicroSmart. For details about the user program execution errors, see Chapter 3 "User Program Execution Errors" in the "FC6A Series MicroSmart LAD Programming Manual".

Note: For details on the user communication client and user communication server specifications and for details on user communication over Ethernet, see "User Communication via Ethernet Communication" on page 5-35.

ERXD (User Communication Receive over Ethernet)

The ERXD instruction receives data from an external device connected over Ethernet, converts the received data in the specified format, and stores the converted data to data registers.

When the input is on, the received data designated by S1 is received from the device connected with the specified connection.

When all data has been received, the device designated by D1 is turned on. Receive status (the receive status and error code) is stored to the device designated by D2.

The byte count of received data is stored to D2+1.

When user communication receive instruction cancel flag (M8200 - M8207) is turned on while receiving incoming data, the execution of all active receive instructions for the corresponding connection is canceled.

Apart from the connection settings and the allocation of the user communication receive instruction cancel flags, the settings of ERXD and RXD instructions are the same. For details on RXD instruction, see "RXD (Receive)" on page 5-10.

The ERXD instruction cannot be used in an interrupt program.
