Communication Installation Instructions KT4H/B TemperatureController

These instructions are for communication functions. For detailed operating
instructions, please refer to User’s Manual for the KT4H/B.

Serial communication and Toolport communication cannot be used together.
When performing Serial communication, remove the tool cable (AKT4H820) from
the USB port of the PC and tool connector of the KT4H/B.
When performing Tool port communication,it is not required to remove the Serial
communication cables. However,do not send a command from the master side.

PLC

FG

Shieldedwire

Connectonlyone sideoftheshieldedwire to the FG terminalsothatcurrentcannot
flowto the shielded wire.If both sidesofthe shielded wire are connected to the FG
terminal, the circuit will be closedbetween the shielded wire and the ground. As a
result, current will run through the shielded wire and this may cause noise.Be sure
togroundthe FG terminal.

Terminator(Terminal resistor)

Do not connect terminator with the communicationline because each KT4H/B has
built-inpull-upandpull-downresistorsinsteadof aterminator.
If there is a large distance between the PLC and the KT4H/B, connect the
terminator on the PLC side.(Connecta terminatorof120 ormoreresistance.)

4. Communication procedures

Communication starts with command transmission from the host computer
(Master) and ends with the response of the KT4H/B (Slave).

(Fig.4-1)

RS-485 communication timing

Master side (Notice on programming)

Set the program so that the master can disconnect the transmitter from the
communication line within a 1 character transmissionperiod after sending the
command in preparation for reception of the response from the slave.
To avoid the collision of transmissions between the master and the slave, send
thenextcommand aftercarefullychecking thatthemasterreceivedthe response.

Slave side

When the slave starts transmission through the communication line, the slave
is arranged so as to provide an idle status(mark status)transmission period of
5ms or more (communication response time from 5 to 99ms settable) before
sending the response to ensure the synchronization on the receiving side.
Theslaveis arrangedso as todisconnect the transmitterfrom thecommunication
line within a 1 character transmission period after sending the response.

• Response with data
When the master sends the reading command, the
slave responds with the corresponding set value or
current status.

• Acknowledgement
When the master sends the setting command, the
slave responds by sending the acknowledgement
after the processing is terminated.

• Negative acknowledgement
When the master sends non-existent command or
value out of the setting range, the slave returns the
negative acknowledgement.

• No response
Theslavewillnotrespondtothemasterinthefollowing cases.

• Global address “FF” (MEWTOCOL) is set.

• Broadcast address (Modbus protocol) is set.

• Communication error (framing error,parity error)

• LRC discrepancy (Modbus ASCII mode)

• CRC-16 discrepancy (Modbus RTU mode)

Методы тестирования

Заводская установка по умолчанию: выходное напряжение 330 в, выходной ток 30 мА. Вы можете протестировать подсветку телевизора с любым размером в этих настройках по умолчанию.1. Самостоятельное тестирование: Подключите, включите выключатель питания. Напряжение около 330 В, ток 0; Свяжитесь с зондами вместе, изменение напряжения на 0 и изменение тока на около 50 мА, затем можно начать тестирование.2. При тестировании:Напряжение = 0, короткое замыкание.Напряжение = ‘330V’, открытая цепь.3. Тестирование одного светодиодный бусин (Установите напряжение около 20 в и переключатель тока до 1 мА):А. С правильной полярностью: напряжение показывает на тестере нормальный светодиодный шарик составляет около 80% от номинального напряжения, например, рабочее напряжение светодиодный шарик 2,4 V в том случае, если его номинальное напряжение 3В;B. С неправильной полярностью: напряжение Отображает напряжение открытой цепи.4. Светодиодный тест-полоски: Установите напряжение около 200 в, измените ток, если требуется Регулировка яркости.
